Laser Safety Information
This product may use Class 1 lasers to communicate over the fiber optic conduc-
tors. The U.S. Department of Health and Human Services (DHHS) does not
consider Class 1 lasers to be hazardous. The International Electrotechnical
Commission (IEC) requires labeling information that states that the lasers are
Class 1.
Labeling Requirements
There are no caution or danger labels required for use of the optical Gigabit Inter-
face Converter (GBIC) since it is a Class 1 laser component assembly. Within the
U.S., the only laser safety label required is the certification label that already
appears on the plastic retainer of the optical GBIC assembly. Outside of the U.S.,
the IEC 825 laser safety standard requires that the system level product have a
Class 1 information label permanently attached and clearly visible whenever
access to the optical ports is possible. This label is supplied with the equipment
and applied by the user during the installation procedure. Refer to Section 2 Instal-
lationl. An example of the IEC Class 1 information label and its dimensions,
suitable for use in most European countries, is shown below. The label consists of
black printing on a yellow background. The languages represented on this example
label are English, German, Finnish, and French and represent the minimum set for
acceptance of a Class 1 product in most European countries.

Section 1 General Description
Introduction
The SANbox™-16HA High Availability Fibre Channel (FC) Switch is the Fabric
component of a Fibre Channel compliant network. Figure 1-1 is an illustration of
the Switch. This manual describes the Switch as a full-featured fabric Switch
unless otherwise specified.

Major Fibre Channel Port Features
SANbox-16HA Fibre Channel Switch
1-2 General Description 59005-03 Rev. A Installer’s/User’s Manual
Major Fibre Channel Port Features
Major Fibre Channel port features include:
• Each Switch chassis has 16 Fibre Channel ports. Each port operates at
1062.5 megabaud.
• Any or all 16 ports may be:
Fabric Ports Fabric ports connect to fibre channel public devices and device
loops. A fabric port is self configuring as an F_Port for a public device
or as an FL_port for a loop of public devices. Refer to “Fabric Port
Overview” on page 1-3.
SL_Ports Segmented Loop Ports (SL_Ports) allow you to divide a Fibre
Channel Private Loop into multiple segments. Each segment of the loop
can pass frames around as an independent loop and can also connect
through the fabric to other segments of the same loop. Refer to
“Segmented Loop Port (SL_Port) Overview” on page 1-3.
TL_Ports. Each Translated Loop Port (TL_Port) connects to a private loop
and allows connectivity between the private loop devices on the loop
and “off-loop” devices (devices not connected to that particular
TL_Port) such as Public fabric devices and private devices on other
TL_Port loops. Refer to “Translated Loop Port (TL_Port) Overview”
on page 1-6.
T_Ports. Trunk Ports (T_Ports) allow the interconnection of multiple chassis
to form larger fabrics. Refer to Section 5 Multi-Chassis Fabrics.
• All ports support Class 2 and Class 3 Fibre Channel service. Refer to Appen-
dix A Reference Information for more information.
• The Switch supports the maximum Fibre Channel frame size (2148 bytes) for
Class 2 and 3 Fibre Channel service. Refer to Appendix A Reference Infor-
mation for more information.
• All ports are supported by GigaBit Interface Converters (GBICs). GBICs
contain the transmitters and receivers that connect to the interconnection
media. Each GBIC is “hot pluggable”.
• Each port has eight buffer credits. This feature allows a cable length up to 13
km at 1 Gbps without performance degradation. F_Port and T_Port credits
can be extended by chaining ports together. Refer to “Port Buffer Credits” on
page 2-10 for more information about extending port credits. Cable length is
also dependant on the type of GBIC used. Refer to Appendix A Reference
Information for more information.

Installer’s/User’s Manual 59005-03 Rev. A General Description 1-3
• You may populate 2 to 16 ports with GBICs. The choice of ports and GBICs
is yours.
The Switch has been validated with GBICs that support a variety of intercon-
nection media. Refer to “Fibre Channel Ports” on page 1-17 for more infor-
mation.
Fabric Port Overview
All ports on the SANbox-16HA chassis are “Loop-aware” FL_Ports. That is, they
are ports that are able to discover, through the Fibre Channel Fabric Login process,
whether they should function as an F_Port (communicating with an N_Port) or as a
Fabric Loop port (communicating with an Node Loop Port (NL_Port)). Fabric
ports connect to Public devices that conform to the Fibre Channel Standards.
Switch management allows you to force a fabric port to function as an F_Port.
Refer to the Switch Management manual for more information.
The attributes of F_Ports and FL_Ports are described in the Fibre Channel
Standards.
Segmented Loop Port (SL_Port) Overview
You may use Switch management to configure any or all ports on the SANbox-16
chassis as Segmented Loop ports (SL_Ports). SL_Ports connect to devices which
conform to the Fibre Channel-Private Loop SCSI Direct Attach (FC-PLDA)
standard. SL_Ports allow you to divide these Private Loops into multiple segments
which may communicate through the Switch as though they were all part of the
same Private Loop.
A Segmented Loop has greater performance than an un-segmented loop because a
Segmented Loop can have multiple concurrent frame transfers (one per loop
segment) while an un-segmented loop can have only one.

1-4 General Description 59005-03 Rev. A Installer’s/User’s Manual
Figure 1-2 shows a possible topology of a Segmented Loop. In this figure, there are
three distinct loop segments that have been linked (placed in the same segmented
loop zone) together by the Switch as a single Segmented Loop. This means that all
three loop segments share the same address space (same set of Arbitrated Loop
Physical Addresses (AL_PAs)). All devices on the Segmented Loop can see all
other devices as though they were attached to their local loop segment.
Figure 1-2 Segmented Loop Topology Example
Segmented Loop Features
• Switch management allows you to designate any or all ports on a SANbox-16
chassis as SL_Ports.
• SL_Ports connect to devices that conform to the Fibre Channel-Private Loop
SCSI Direct Attach (FC-PLDA) standard. If you place a Public Fibre
Channel device on an SL_Port it becomes a Private device and (like other
Private devices) cannot communicate off the loop.
• Each SL_Port can support up to 126 devices.
• Each SL_Port automatically discovers the devices connected to it.
• Switch management allows you to link up to 32 segments (SL_Ports)
together in the same segmented loop zone (even across multiple chassis in
the same fabric) to form a Segmented Private Loop. The aggregate total
number of devices in the linked SL_Ports must not exceed 126 devices and
all AL_PAs within the linked segments must be unique.

• Devices in the same segmented loop zone communicate with one another as
though they were on the same physical loop.
• Devices on SL_Ports cannot communicate with devices on F, FL or
TL_Ports. They also cannot communicate with devices on SL_Ports which
are not in the same segmented loop zone.
• Devices connected to SL_Ports are not registered with the Name Server.
• Each loop segment may have a Fibre Channel Frame in process.
• You may have as many loop segments as you have SL_Ports. That is, if none
of them are zoned together, each SL_Port would contain one set of AL_PA
and each AL_PA within that loop must be unique.
• The Switch supports all SCSI/FCP and TCP/IP frames.
• SL_Ports support Class 2 and 3 Fibre Channel Service.
SL_Port Management
Refer to the Switch Management manual for more information. The SANsurfer
Web-based Switch management application provides the following:
• The user may choose which ports (if any) are SL_Ports.
• The user may place up to 32 SL_Ports together in the same segmented loop
zone to form each Segmented Loop.
• The application provides a map of all AL_PAs on a Segmented Loop. This
viewable map includes information about which AL_PA address are being
used by the SL_Port.
• The application provides a way to flag error conditions to the user.
• All management configuration information is stored in non-volatile memory.
SL Private Loop Stage Type
Switch management allows you to define a chassis as an SL Private Loop stage
type. This stage type defines all ports on the chassis as SL_Ports and links them
into one segmented loop. If an SL Private Loop chassis is to be used in a cascade
topology, all chassis in that topology must also be SL Private Loop. Furthermore,
an SL Private Loop chassis in a multi-chassis fabric will force all other chassis in
that fabric to behave as SL Private Loop chassis. You may not mix SL Private Loop
chassis with other stage types in the same fabric.
You define an SL Private Loop chassis by selecting SL Private Loop as the stage
type in the Chassis Parameters portion of any Switch Faceplate Display in the
SANSurfer Switch Management application. Refer to the Switch Management
manual for more information.

Translated Loop Port (TL_Port) Overview
You may use Switch management to configure any or all ports on the SANbox-16
chassis as Translated Loop ports (TL_Ports). TL_Ports connect to devices which
conform to the Fibre Channel-Private Loop SCSI Direct Attach (FC-PLDA)
standard. Each TL_Port allows connectivity between the Private Loop devices on
the loop and “off-loop” devices (devices not connected to that particular TL_Port)
such as Public devices connected to F and FL_Ports and private devices on other
TL_Port loops. This connectivity is achieved by having a translation function at
each TL_Port which translates Private frames to Public frames and vice versa.
Figure 1-3 shows possible Fabric topologies with both public and Private SCSI
devices. In this figure, the TL_Ports are ports with Translation Mode functions.
The following three scenarios are supported by TL_Ports:
• Server 1 to ST1 (Public Initiator to/from Private Target)
• Server 2 to ST2 (Private Initiator to/from Public Target)
• Server 3 to ST3 (Private Initiator through fabric to/from Private Target on
different loop)

TCP/IP protocols are also supported. Figure 1-4 shows possible topologies for
TCP/IP:
• Server 1 to and from Server 2 (Public device to/from Private device)
• Server 3 to and from Server 4 (Private device through fabric to/from Private
device on different loop).
Figure 1-4 TCP/IP Example
Translated Loop Features
• Each TL_Port maintains up to 125 AL_PA addresses on the Private Loop.
When one of these AL_PA addresses communicates with an “off-loop”
device, the TL_Port acts as a proxy for the off-loop device on the Private
Loop. This means that the TL_Port handles all loop primitives on behalf of
the off-loop device.
• Each TL_Port may proxy up to 31 off-loop devices. These off-loop devices
must be Public devices (connected to F, or FL_Ports) or Private devices on
other TL_Ports.

• The set of off-loop devices that a single TL_Port may proxy may overlap or
exclude the devices accessed by other TL_Ports in the same fabric.
• The set of off-loop devices proxied by a TL_Port is contained in its transla-
tion entries list.
The translation entries list for a TL_Port connected to Private targets will
contain the initiators (both Public and Private) that try to communicate with
those targets. An Auto Learning feature automatically adds these initiators to
the ports’ translation entries list. Use Zoning to limit the number of initiators
to 31 or less. You may disable Auto Learning for any TL_Port via Switch
management. The default for each TL_Port is Auto Learning enabled.
The translation entries list for a TL_Port connected to Private initiators will
contain the targets (both Public and Private) that you want the Private initia-
tor to communicate with. Auto Learning is not able to enter these targets into
the translation entry list. The translation entries list cannot exceed 31 entries.
Switch management allows you to manage the translation entries list for
these TL_Ports. Auto Learning should be disabled for these TL_Ports
connected to Private initiators.
• You may disable Auto Learning for any TL_Port via Switch management.
The default for each TL_Port is Auto Learning enabled.
• Devices on TL_Ports cannot communicate with devices on SL_Ports.
• TL_Ports support Broadcast.
• Multiple TL_Ports can coexist in a single fabric. They may be zoned to
control access.
• Devices connected to TL_Ports are registered with the Name Server.
• The user must identify Public Targets and Initiators for each TL_Port.
• TL_Ports support all SCSI/FCP frames.
• TL_Ports support TCP/IP.
NOTE:
Third Party SCSI commands (i.e. Third Party RESERVE, COPY, XOR) are
not supported. A Third Party SCSI command is any command that has a
target address embedded in the command (i.e. embedded in the Fibre
Channel frame payload).

Refer to the Switch Management manual for more information. SANsurfer Switch
management provides the following:
• The user may choose which ports (if any) are TL_Ports.
• The user may use Name Server Zoning or Hard Zoning to limit the number
of Public devices that have access to a particular TL_Port to 31 devices or
less.
• The user may disable the Auto Learning feature for any TL_Port. The default
for each TL_Port is Auto Learning enabled.
• The user may manage the translation entries list for any TL_Port connected
to Private initiators. That is, the user may identify all off-loop targets for the
initiators on the particular TL_Port. Auto learning should be disabled for
these TL_Ports.
• SANsurfer provides a map of all AL_PAs on a Translated Loop. This
viewable map includes information about which AL_PA addresses are being
used by the TL_Port.
• SANsurfer provides a way to flag error conditions to the user.
• All switch management configuration information is stored in non-volatile
memory.
• The user may clear the stored configuration information.
Major Switch Chassis Features
The following is an overview of the major features of the Switch chassis:
• A chassis can be defined as one of three stage types: Input/Output Transfer
(IO/T), Cross Connect (CC), or SL Private Loop. An IO/T chassis supports
all port types (F, FL, SL, TL, and T). A CC chassis supports only T_Ports as it
serves as a bridge between many IO/T chassis. An SL Private Loop chassis
supports SL_Ports and T_Ports. Refer to“Three Multi-Chassis Topologies”
on page 5-2 for more information about IO/T and CC stage types. Refer to
“SL Private Loop Stage Type” on page 1-5 for more information about the
SL Private Loop Stage Type.
• You have the option to add a second power supply for total power supply
redundancy. When there are two power supplies, they each become “hot
pluggable”. Refer to “Power Supply(s)” on page 1-24 and also to Section 4
Removal/Replacement Procedures.
Preliminary
Major Switch Chassis Features
SANbox-16HA Fibre Channel Switch
1-10 General Description 59005-03 Rev. A Installer’s/User’s Manual
• Each chassis has two separate AC power inputs, one for each power supply.
The left AC power input provides input power to the left power supply. The
right AC power input provides input power to the right power supply.
• The Switch performs Power-On-Self-Tests (POSTs) each time it is powered-
up. POST provides one pass through the battery of tests, but does not test the
GigaBit Interface Converters (GBICs). The POST uses the Heartbeat LED to
indicate pass or fail test conditions. Refer to “Heartbeat LED (Yellow)” on
page 1-20 and“Power-On-Self-Test (POST)” on page 3-6.
• LEDs indicate the status of the Switch and each port. Refer to“Front Panel
LEDs” on page 1-20.
• The Switch contains an RJ-45 Ethernet connector that provides a manage-
ment connection to the outside world. The user can use a management station
connected via this network to manage the Switch. Refer to “Major Switch
Management Features” and “Switch Management Connector” later in this
section, and the Switch Management manual for more information.
• The Switch chassis may be connected to other Switch chassis to expand the
number of user ports. Refer to Section 5 Multi-Chassis Fabrics for more
information.
• The Switch chassis is shipped from the factory physically configured with
rubber feet on its bottom that allow it to sit on a flat surface and stack.
Mounting brackets (in a separate packet shipped with the Switch) allow you
to mount it in a 19-inch rack. When mounted in a rack, the Switch must be
supported by rails or a shelf. Refer to Section 2 Installation for the install
procedure and to Appendix A Reference Information for the dimensions and
type of rack.
• SANbox switch fabrics support the use of MKII switches as IO/T chassis in
mesh and Multistage™ topologies. Refer to “Three Multi-Chassis Topolo-
gies” on page 5-2 for more information about MKII compatibility.

Hard Zones
Hard zones allow the division of the fabric (one or more Switch chassis) into
as many as 16 fabric-wide zones that define the ports that may communicate
with each other. A port may communicate with any other port that is in the
same hard zone as it is defined. If hard zones cross chassis boundaries in a
multi-stage topology, the interconnecting T_Port, or ports must be placed in
the same hard zone that they interconnect. Refer to Section 5 Multi-Chassis
Fabrics. A particular F, FL, TL, or T_Port may be placed in only one hard
zone (no overlapping hard zones). If hard zones are enabled, broadcast zones
and Name Server zones do not cross the defined hard zone boundaries.
Broadcast Zones
Broadcast zones allow the division of the fabric into as many as 16 zones that
define the ports that receive Broadcasts. A particular F, FL, or TL_Port may
be placed in one or more of these broadcast zones. A port will broadcast to all
ports in the same broadcast zone (or zones) in-which the port is defined. If
hard zones are enabled, broadcast zones do not cross the defined hard zone
boundaries. Broadcast zones may overlap each other. T_Ports are not affected
by broadcast zones.
Name Server Zoning by Port
Name server zoning by port allows the division of the fabric into as many as
256 zones that define the ports that receive Name Server information. A
particular F, FL, or TL_Port may be defined in one or more of Name Server
zones. A port will receive Name Server information for all zones of which it
is a member. If hard zones are enabled, Name Server zones do not cross the
defined hard zone boundaries. Name server zones may overlap each other.
T_Ports are not affected by Name Server zones.

Server zones of which it is a member. If hard zones are enabled, Name Server
zones do not cross the defined hard zone boundaries. Name server zones may
overlap each other. T_Ports are not affected by Name Server zones.
Segmented Loop Zones
Segmented loop zones allow the division of the fabric into as many as 256
zones that define the SL_Ports that may communicate with each other. Each
segmented loop zone can have a maximum of 32 SL_Ports, and each AL_PA
within a segmented loop zone must be unique. You can zone individual
SL_Ports together, or all SL_Ports on a chassis by defining the chassis as an
SL Private Loop stage type. Refer to “SL Private Loop Stage Type” on

SANbox-16HA Fibre Channel Switch
1-20 General Description 59005-03 Rev. A Installer’s/User’s Manual
Front Panel LEDs
Refer to Figure 1-5. LEDs visible through lenses in the front of the chassis indicate
chassis and port status. During a Reset operation (for about two seconds at the
beginning of power-up) all LEDs are forced ON. The following definitions are
valid following the Power-On-Self-Test (POST) when the POST finds no errors.
Refer to Section 3 Diagnostics/Troubleshooting, for information about how the
LEDs act if the POST finds an error or if the control code (located in Flash
memory) hangs up.
Heartbeat LED (Yellow)
The Heartbeat LED indicates the status of the internal Switch processor and the
results of Power-On-Self-Tests (POSTs) run at power-up.
Following a normal power-up the Heartbeat LED blinks about once per second to
indicate that the Switch passed the POSTs and the internal Switch processor is
running.
Refer to Section 3 Diagnostics/Troubleshooting, for more information about
Heartbeat LED error codes.
Switch Logic Power Good LED (Green)
This LED is ON when any Power Supply is delivering power within normal limits
to the Switch logic (the Power Button must also be depressed). If you have redun-
dant power supplies, the Power Good LED will stay ON even when one power
supply stops working and the other picks up the load. The LED will go OFF when
no supply is delivering the proper logic voltages.
Power Supply Fail LED (RED)
This LED is normally OFF. It comes ON only when one supply in a redundant
configuration fails, but the other supply has picked up the load. When this LED is
ON, it is a signal to look at the Power Supply LEDs on the back of each Power
Supply to determine which supply failed. Refer to Figure 1-5 for the location of the
power supplies and their LEDs. This LED is not meaningful in a system with only
one Power Supply.

Over Temperature LED (Red)
This LED is normally OFF. The over temperature LED illuminates to indicate that
the air temperature inside the switch has exceeded a certain limit. If this LED
illuminates, inspect the following:
• Ambient air temperature: maximum 40°C (104°F)
• Proper clearance: 163mm (6.5”) front, left side, and back
• Fan operation
• Power supply operation
If the over temperature LED remains illuminated, contact your authorized mainte-
nance provider (refer to Appendix B ).
Logged-In LED (Green)
Each port has its own Logged-In LED. The Logged-In LED indicates the logged-in
or initialization status of the connected device or loop of devices. A T_Port
Logged-In LED will blink to indicate that the switch has been disabled due to a
chassis number conflict.
Normal Operation
Initially (immediately after the Switch successfully completes the POST), the
Switch holds all Logged-In LEDs OFF (no light). They each remain OFF until the
port and its attached devices are able to successfully perform a loop initialization
(LIP) or port log-in. Following a successful LIP or log-in on a particular port, the
Switch turns the Logged-In LED ON (lit) for that port. This shows that the port is
properly connected and able to communicate with its attached device/s. The LED
for this port remains ON as long as the port is initialized or logged-in.
If the established/logged-in link is broken (a fiber opens or the connected port goes
out of service), the Logged-In LED is shut OFF. If the link is replaced or the
connected port comes back into service, the port and its attached device/s will try
to regain its initialized or logged-in status. If the initialization/log-in is once again
established, the Switch turns the Logged-In LED back ON and communication
continues.
It is best to have the Switch operating before the attached nodes are powered up.
Duplicate Chassis Number Warning
Upon T_Port Login, if the fabric senses two switches of the same stage type (cross-
connect or IO/T) with the same chassis number, the switch with the higher world
wide name will be disabled. In addition, the affected port Logged-In LEDs on both
switches will blink to indicate that a conflict exists. Refer to “Multistage
Topology” on page 5-12 for more information about stage types.

one frame. This LED will not light for frames following an arbitrated loop in
bypass mode.
AC Input Power Connectors and Fuses
Refer to Figure 1-5. The chassis contains two Input Power Assemblies, one for
each power supply. The left assembly serves the left Power Supply. The right
assembly serves the right Power Supply. Each assembly contains a connector for a
standard 3-wire computer-type AC power cable (supplied with the Switch). The
power cable connects between an AC Input Power Connector and an AC outlet. For
purposes of redundancy, the AC outlets should be on separate circuits. Refer to
Appendix A Reference Information for the AC Power Requirements. See also
Section 2 Installation for installation procedures.
An Input Fuse Holder is incorporated into each AC Input Power Connector
assembly. they each hold two input fuses. Refer to Section 3 Diagnostics/Trouble-
shooting and to Section 4 Removal/Replacement Procedures. Refer also to
Appendix A Reference Information for fuse size.
Switch Management Connector
Refer to Figure 1-5. The Switch Management Connector is a 10/100BASE-T

Power Supply(s)
The chassis has bays for two power supplies. When there is only one supply, it can
operate from either bay and the unused bay is covered with a plate.
The fan on a Power Supply also furnishes cooling for the Switch chassis. A Power
Supply fan draws air from the front of the chassis and expels it from the back of the
chassis. One Power Supply with its cooling fan is sufficient to operate the Switch.
When there are two Power Supplies, they each become “hot pluggable”. That is,
either supply may be removed while the Switch is operating. As long as one good
supply remains in operation, the Switch will operate properly. Refer to Section 3
Diagnostics/Troubleshooting and Section 4 Removal/Replacement Procedures.
The Power Supply(s) operate independently of the Power Button on the front of the
chassis. The supply(s) fan(s) starts to turn and the supply(s) start to produce logic
voltages as soon as the chassis is connected to AC power. These logic voltages may,
or may not, be enabled out of the power supply into the Switch logic. That depends
on the position of the Power Button on the front of the chassis.
Each Power Supply has two lights that indicate its status. Refer to Figure 1-8 for
their location.

within their proper voltage ranges and the Power Button is On. The light is Off
when its supply is not producing proper logic voltages or the Power Button is out
(OFF). The Power Button on the front of the chassis must be in the ON position in
order to enable the logic voltages into the Switch logic.
Over Temperature Light (Red)
The Over Temperature Light is normally OFF. When the power supply senses an
overheat condition (airflow blocked or fan stopped) it turns the Over Temperature
Light On and disables its logic voltages. This will turn its own Power Supply Good
Light OFF and, if it was the only power supply in the Switch, it would power down
the Switch. If there was another power supply installed in the Switch, the Power
Supply Fail LED on the Switch’s front panel would turn ON and the Switch would
continue to operate with the other power supply.
When the overheated power supply cools down, the power supply will attempt to
place itself back in service. If the cause for the overheating condition is still
present, the power supply will eventually overheat again and the shutdown process
will repeat. During the periods where both power supplies are operating, the Power
Supply Fail LED on the front of the chassis will turn OFF. The Power Supply Fail
LED will only be ON when one of the two power supplies is actually failing.

Section 2 Installation
Introduction
There are nine basic steps required to install the Switch.
1. Unpack
2. Place or Mount the Equipment
3. Apply the IEC Laser Safety Label (If the installation contains fiber optic
GBICs and is in Europe)
4. Install the GBICs
5. Connect the Switch to AC power
6. Check the Power-On-Self-Test (POST) results
7. Cable Fibre Channel Devices to the Switch
8. Configure the chassis
9. Configure the ports
Unpack
1. Unpack the Switch from the carton. There are no packing materials or
shipping fixtures located inside the chassis.
2. Ensure that the power cable has a plug that is suitable for your location.
QLogic supplies the Switch with a standard 3-wire computer-type power
cable. One end has an IEC 320 plug that mates with the power connector on
the front of the chassis. The other end must have a plug that is suitable for
your location. If the power cable has the wrong connection for your location,
you must supply your own. Refer to the specifications on page 2-5.
3. GBICs (if you have ordered them from QLogic) are packaged separately.
QLogic supplies one Loopback Plug for each type of GBIC you ordered. A
Loopback plug is a plug that, when fully inserted into a GBIC port, intercon-
nects transmit and receive for that port. In case of a suspected GBIC failure,
you may use these Loopback Plugs, in conjunction with a test, to verify the
operation of a GBIC. Refer to “Fibre Channel Port Loop-back Test Failure (8
Blinks)” on page 3-10 for more information.

Place or Mount the Equipment
SANbox-16HA Fibre Channel Switch
2-2 Installation 59005-03 Rev. A Installer’s/User’s Manual
Place or Mount the Equipment
The Switch may be placed on a flat surface and stacked, or mounted in a 19” EIA
rack. The Switch comes with rubber feet on the bottom for placing it on a flat
surface.
Air flow is front-to-back. The top of each chassis has dimples for the rubber feet of
a chassis stacked on top. Allow 163mm (6.5”) front, left side, and back.
Shelf Mount
If you are not going to rack-mount the Switch, simply place it on a flat surface
being careful not to obstruct the air flow through the chassis.
Rack Mount
If you mount the Switch in a rack, you must install the rack-mounting brackets
supplied with the Switch. You may also need to remove the Switch’s rubber feet.
They are easily removable in case they are not compatible with your rack. Without
the rubber feet, the Switch occupies 2U of space in an EIA rack.
NOTE:
If this chassis is part of a Multistage Switch please read Section 5 Multi-Chassis
Fabrics. It may affect the way you place or mount this chassis.
NOTE: Rack Mounting Considerations
• The chassis must be installed on rails or on a shelf. The rack mounting brack-
ets cannot support the weight of the chassis.
• If the chassis is mounted in a closed or multi-unit rack assembly, the tempera-
ture of the chassis operating environment may be greater than the ambient
temperature of the room. Make sure that the operating temperature inside the
rack enclosure does not exceed the maximum rated ambient temperature as
defined in Appendix A Reference Information.
• Do not restrict the chassis airflow. Refer to Figure A-1 and Figure A-2 for
clearance information.
• Multiple rack-mounted units connected to the AC supply circuit may overload
that circuit or overload the AC supply wiring. Refer to the nameplate ratings
or Power Source loading in Appendix A Reference Information for clearance
information.
• Reliable grounding (earthing) in the rack must be maintained from the Switch
chassis to the AC power source. Please refer to the Danger notices on
page 2-5.
Preliminary
Place or Mount the Equipment
SANbox-16HA Fibre Channel Switch
Installer’s/User’s Manual 59005-03 Rev. A Installation 2-3
The following steps describe how to mount the chassis in a rack:
1. Mount the Brackets. The chassis must sit on rails or a shelf in the rack or
cabinet. Refer to Figure 2-1. The Switch is shipped with a package
containing cabinet mounting brackets. The screws are already in the chassis
so you must remove them and reuse them to mount the brackets. Mount these
brackets on either the front or back corners of the chassis.
2. Place the Switch in a 19” EIA rack and secure it with eight (8) 10-32
machine screws (not supplied). If the vertical space is sufficient, you may
leave the rubber feet on the Switch chassis. If the vertical space is not suffi-
cient, you may remove the rubber feet by turning them counterclockwise by
hand (or with a flat-blade screwdriver).

Refer to Appendix A Reference Information for Switch power requirements.
1. Connect the power cable to the front of the chassis.
2. Connect the other end of the power cable to a 3 wire, grounded, AC outlet
that delivers power in accordance with the power requirements specified in
Appendix A Reference Information. Press the Power Switch to the ON
position. Refer to Figure 1-5 for its location.
The 3-wire grounded power circuit and the 3-wire power cable provide adequate
grounding for the Switch.
Switch Logic Power Good LED
The Switch Logic Power Good LED on the front of the chassis will light when at
least one of the two Power Switches has been in the ON position for two or more
seconds, and the power supply is supplying DC power within its normal operating
limits. Refer to Figure 1-5 for the location of the LED.
If the Power Good LED fails to light about two seconds after the Power Switch is
pressed to the ON position, ensure that both ends of the appropriate power cord are
properly plugged in, the AC power source is turned ON, and that the input fuses for
that power input are good.
If you have checked these things and the Power Good LED still is not lit, contact
QLogic Customer Support or your authorized maintenance provider. Do not
proceed to the next step unless the Power Good LED is lit.
Check the Power-On-Self-Test (POST) Results
When the Power Supply applies DC power to the Switch logic, the logic runs a
Power-On-Self-Test (POST) diagnostic. POST tests the condition of firmware,
memories, data-paths, and Switch logic and uses the Heartbeat LED to indicate
pass or fail conditions. Refer to Section 3 Diagnostics/Troubleshooting for a
description of POST.
About three seconds after the Power Good LED comes on, POST will be complete.
At this point the Heartbeat LED will start to indicate whether or not there is a
POST error. Check the Heartbeat LED. Figure 1-5 shows the location of the Heart-
beat LED.
If the Heartbeat LED is blinking about once every second, the POST passed and
you may go to the next step.
If the Heartbeat LED is not blinking once every second, the POST failed. Note
what the Heartbeat LED is indicating (by the flash pattern) and contact QLogic
Customer Support or your authorized maintenance provider. Do not proceed to the
next step unless the POST passed.
Preliminary
Cable Fibre Channel Devices to the Switch
SANbox-16HA Fibre Channel Switch
2-8 Installation 59005-03 Rev. A Installer’s/User’s Manual
Cable Fibre Channel Devices to the Switch
There are two types of Fibre Channel devices, Public and Private.
Public Devices
Public devices have full Fibre Channel addressing capability and therefore can
communicate with any other Public device on the fabric. They may be connected
directly to the Switch (one device per port) or arranged in an Arbitrated Loop with
up to 126 devices in the loop and the loop connected to the Switch.
Public devices connect to FL_Ports. Each FL_Port is able to discover, through the
Fibre Channel Login process, whether it is to function as a Fabric Port (F_Port) or
as a Fabric Loop (FL_Port). Most Fibre Channel Adapters in Public devices
support both loop and non-loop operation.
Switch management allows you to force any FL_Port to operate in F_Port mode
when you connect it to a device that can act in either mode.
For example, one of these devices is a server that can be placed on a loop (port
operating in loop mode) or connected directly to the Switch (port operating non
loop mode). You may decide to connect it directly to the Switch and force the port
to operate in F_Port (non loop mode). It would not be efficient for the Switch port
to function as though it was connected to a device on a loop. So, use Switch
Management to force the Switch port to function as an F_Port.
Another example is connecting a RAID to the Switch. The RAID is also a device
that is capable of operating on a loop or connected directly to the Switch. If this
device is connected directly to the Switch it may be more efficient to force the
Switch port to function as an F_Port.
If the attached devices really are arranged in a loop (a Hub or JBOD for example)
with no controller, allow the Switch port to function as an FL_Port.
Private Devices
Private devices do not have full Fibre Channel addressing capability. They only
have the Arbitrated Loop Physical Address (AL_PA) portion of the Fibre Channel
Physical Address. These devices only exist on loops and unless the Switch offers
extra support, these devices cannot communicate outside their own loop.
NOTE:
• If this chassis is part of a Multistage Switch, please read Section 5 Multi-
Chassis Fabrics and follow the cabling instructions in that section before
cabling the Fibre Channel Devices to the Switch.
• If this chassis is an SL Private Loop chassis, refer to “SL Private Loop Stage
Type” on page 1-5.
Preliminary
Cable Fibre Channel Devices to the Switch
SANbox-16HA Fibre Channel Switch
Installer’s/User’s Manual 59005-03 Rev. A Installation 2-9
Private devices connect to Segmented Loop Ports (SL_Ports) or Translated Loop
Ports (TL_Ports). Use Switch Management to configure SL or TL_Ports. Refer to
Section 1 General Description for a description of SL and TL_Ports. Refer to
“Configure the Ports” on page 2-18.
Mixing Public and Private Devices on the Same Loop.
You may place a Private device on a Public loop but the Private device will not be
able to communicate outside the loop.
You may place a Public device on a Private loop but the Public device functions as
a Private device.
Switch Ports
Any Fibre Channel port on the Switch may be an FL_Port, SL_Port, TL_Port, or a
T_Port. Refer to Section 5 Multi-Chassis Fabrics for a description of T_Ports. The
type of media used (fiber optic cable or copper) depends on the type of Fibre
Channel adapter in the attached device and the type of GBICs used in the Switch.
You may populate the Switch with any assortment of approved GBICs appropriate
for your interconnection media type.
Tuning
You can optimize the system performance by connecting devices which have the
greatest amount of traffic to ports on the Switch which are most efficiently inter-
connected.The most efficient performance is within a group of four ports on the
same Application-Specific-Integrated-Circuit (ASIC). These groups are:
• Ports 1-4
• Ports 5-8
• Ports 9-12
• Ports 13-16
When a frame source-port and destination-port are within the same port group, you
will realize:
• The lowest Class 2/Class 3 frame latency
• The highest Class 2/Class 3 point-to-point bandwidth
• The highest Class 2/Class 3 aggregate bandwidth
When a frame source-port and destination-port are not within the same port group
the interconnection is slightly less efficient.
Preliminary
Cable Fibre Channel Devices to the Switch
SANbox-16HA Fibre Channel Switch
2-10 Installation 59005-03 Rev. A Installer’s/User’s Manual
Distance
The maximum distance between each adapter and the Switch depends on the type
of GBICs and the type of cable installed. Refer to Appendix A Reference Informa-
tion for this information. Also, the speed and Fibre Channel Revision Level of each
adapter must be compatible with the Switch and the type of I/O media of each
adapter must be compatible with the particular GBIC on the Switch.
Port Buffer Credits
Each port has eight buffer credits. This allows a cable length up to 13 km at 1 Gbps
without performance degradation. Buffer credits can be extended for F_Ports and
T_Ports to maintain performance over longer cable lengths. Credits are extended
by chaining ports together. You can chain 1, 2, or 3 donor ports to the recipient
F_Port or T_Port adding 8 credits for each chained port. For example, chaining one
donor ports yields 16 credits, two donor ports yields 24 credits, and three donor
ports yields 32 credits.
To extend buffer credits, the switch must be cabled and configured properly. The
recipient F_Port or T_Port must be configured for extended credits using switch
management. The following rules apply when chaining ports:
• Credits can be extended only for F_Ports and T_Ports. The recipient F_Port
or T_Port must occupy the lowest numbered port in an ASIC group. For
example, port 1 or port 5 can be credit recipients, but not port 2. Refer to
“Tuning” on page 2-9 for information about ASIC groups.
• Define recipient ports by port mode using switch management. Port modes
for recipient F_Ports are: F_Ext16, F_Ext24, or F_Ext32. For example, to
extend credits for port 1 to 32 credits as an F_Port, define the port mode as
F_Ext32. Ports 2, 3, and 4 automatically become credit donors ports, and any
external connections to the donor ports are disabled. To chain T_Ports, define
recipient and donor ports as you would for an F_Port. When you cable the
T_Port, it will self-configure with extended credits.
• The recipient port and all donor ports must be members of the same ASIC
group. For example, you can chain ports 1 through 4, and 5 through 8, but not
3 through 6. Refer to “Tuning” on page 2-9 for information about ASIC
groups.
• Chained ports must be sequential. For example, if port 5 is the recipient port,
you can chain ports 5 and 6, but not 5 and 7.

All GBICs and cables are “hot-pluggable”. That is, you may have the Switch
powered-up while you plug or unplug GBICs or cables of any interconnection

Fiber Optic Connections
Keys on “Duplex” cable assemblies (a connector-pair containing both transmit and
receive fastened together in one unit), prevent you from connecting them incor-
rectly.
On the Switch end of the connection, on the top row of ports, the transmit
connector is the right-hand connector of each pair. On the bottom row of ports, the
transmit connector is the left-hand connector of each pair.
On the device end, you will have to consult the appropriate adapter or device
manual to determine the connector orientation.
In some cases you may need to connect a loop of devices to the Switch without the
use of a Hub. Note in Figure 2-5 that these devices are connected in a loop from the
transmit side of a loop port on the Switch, through each device in the loop, then
back to the receive side of the original loop port on the Switch. Connect the
transmit connector on a loop port to the receive connector on the first device in the
loop. Continue to connect each device in the loop, transmit to receive. Then
connect the transmit connector on the last device in the loop to the receive
connector of the same loop port on the Switch that you connected to the first
device in the loop.
Copper Connections
HSSDC and DB-9 connectors are duplex cable assemblies. That is, both the
transmit and receive contacts are part of the same keyed plug assembly. You can’t
plug them in wrong. Connect one end of the cable to the Loop device and the other
end to a port on the Switch.
Examples
Figures 2-4 through 2-7 are examples of device connections to a single chassis
switch. The same concepts apply to fabrics containing multiple chassis.

SANbox-16HA Fibre Channel Switch
Installer’s/User’s Manual 59005-03 Rev. A Installation 2-17
Configure the Chassis
If this chassis is part of a Multi-Chassis fabric, follow the instructions in
“Chassis Configuration” on page 5-18.
If this is a single chassis switch, the only configuration necessary is the
Ethernet port. To configure the chassis, do the following:
1. Physically connect a management station to the ethernet port of the chassis
through which the fabric will be managed.
Follow the ethernet cabling instructions in the Switch Management manual
to install the Switch temporarily on an isolated Ethernet network with the
subnet address 10.x.x.x (By default, the Switch’s IP address is 10.0.0.1.). Use
a crossover cable to connect the management station to the switch chassis.
This network does not need to contain anything more than the switch and a
single management host to configure the switch. You may then use the
SANsurfer Switch management application to configure the switch chassis’
ethernet port.
2. Configure the ethernet port of the switch chassis. Refer to the Switch
Management manual for information about configuring the ethernet port.
You must reset the switch chassis to cause it to use its new IP address. Reset
the switch chassis by cycling its power or using the SANsurfer Switch
management application.
3. Following the reset operation, you may move the ethernet connection to the
switch chassis from its temporary isolated network to its normal ethernet
network.
If you are configuring a single chassis switch, the chassis configuration is
complete.
Preliminary
Configure the Ports
SANbox-16HA Fibre Channel Switch
2-18 Installation 59005-03 Rev. A Installer’s/User’s Manual
Configure the Ports
Use Switch Management for all port configuration.
Fabric Ports
The default mode of each Switch port is FL. That is, each port can automatically
discover that it must operate as an F_Port if it is connected to an N_Port device
adapter or operate as an FL_Port if it is connected to an NL_Port device adapter.
Some device adapters are N_Port only, other device adapters are NL_Port only, and
the F_Port has no problem discovering its proper mode.
You must help the configuration process when you connect a device adapter that
can operate in either N_Port (non-loop) or NL_Port (loop) mode. Switch manage-
ment allows you to force any FL_Port to operate in F_Port mode when you connect
it to a device that can act in either mode.
For example, one of these devices is a server that can be placed on a loop (port
operating in loop mode) or connected directly to the Switch (port operating non
loop mode). You may decide to connect it directly to the Switch and force the port
to operate in F_Port (non loop mode). It would not be efficient for the Switch port
to function as though it was connected to a device on a loop. So, use Switch
Management to force the Switch port to function as an F_Port.
Another example is connecting a RAID to the Switch. The RAID is also a device
that is capable of operating on a loop or connected directly to the Switch. If this
device is connected directly to the Switch it may be more efficient to force the
Switch port to function as an F_Port.
If the attached devices really are arranged in a loop (a Hub or JBOD for example)
with no controller, allow the Switch port to function as an FL_Port.
SL_Ports
Use SANsurfer Zoning to place up to 33 segments (SL_Ports) together in the same
segmented loop zone (even across multiple chassis in the same fabric) to form a
Segmented Private Loop. The aggregate total number of devices on the SL_Ports
in the same segmented loop zone must not exceed 126 devices and all AL_PAs
within the linked segments must be unique.
All SL_Ports in the same segmented loop zone must also be in the same Hard
Zone. Name Server Zones and Broadcast Zones do not apply to SL_Ports.

TL_Ports
The set of off-loop devices proxied by a TL_Port is contained in its translation
entries list.
The translation entries list for a TL_Port connected to Private initiators will
contain the targets (both Public and Private) that you want the Private initiator to
communicate with. Auto Learning is not able to enter these targets into the transla-
tion entry list. Switch management allows you to manage the translation entries list
for these TL_Ports. You may disable Auto Learning for these TL_Ports connected
to initiators or targets. Use the Port Display/TL Configuration window in
SANsurfer to manage the translation entries list for each TL_Port.
The translation entries list for a TL_Port connected to Private targets will contain
the initiators (both Public and Private) that try to communicate with those targets.
An Auto Learning feature automatically adds these initiators to the ports’ transla-
tion entries list. Use Zoning to limit the number of initiators to 31 or less. You may
disable Auto Learning for any TL_Port via Switch management. The default for
each TL_Port is Auto Learning enabled. Refer to the Switch Management manual
for information about managing the translation entries list for each TL_Port.
T_Ports
T_Ports interconnect chassis in a multi-chassis topology. Any port connected to
another Switch chassis automatically becomes a T_Port (no configuration is neces-
sary). Refer to Section 5 Multi-Chassis Fabrics for more information.

Tuning Ports for Multi-Frame Sequences
In most circumstances, tuning of an individual port is not desirable, and the default
setting (Normal) should be left unchanged. However, certain Host-Bus-Adapters
(HBA) perform better with tuning. To support optimum performance with these
HBAs, the Switch allows individual ports to be tuned based on the characteristics
of a particular HBA. Tuning modes supported are:
Non-I - Non-Interleaved This option prevents sequences from different sources and
bound for a single destination from being interleaved. Once a sequence has
begun, the Switch will not transmit frames from any source other than the
one which began the sequence. This mode is recommended only for Tachyon-
based adapters being used for IP traffic. It is not recommended in any other
circumstance. If the fabric consists of multiple Switches, Non-I must also be
selected on any Cross Connect port that will be used as a route to the
Tachyon.
Min-I - Minimize-Interleave This option, while not preventing interleaved sequences,
minimizes their extent. Once a sequence has begun, the Switch will continue
to transmit from the same source as long as frames are available for transmis-
sion or end of sequence occurs. If no frames are available for transmission,
then a new source will be started and held until it has no frames to transmit or
end of sequence occurs. This mode is recommended for Qlogic 2xxx HBAs.
Frame-L - Frame Limit This option limits the number of frames that can be transmit-
ted during a single loop tenancy to 32. This option is recommended for JNI
HBAs based on the Adaptec ASIC, and Adaptec HBAs.
Normal No tuning applied. Recommended for all situations not mentioned above.
Use the Port Tuning faceplate in SANsurfer if it is necessary to tune a port for
multi-frame sequences.
Preliminary
Zoning
SANbox-16HA Fibre Channel Switch
Installer’s/User’s Manual 59005-03 Rev. A Installation 2-21
Zoning
SANbox switches use the following types of zoning to restrict or extend access to
devices in the fabric:
• Hard zones
• Name Server zones
• Segmented loop zones
• Broadcast zones
Refer to Section 5 Multi-Chassis Fabrics for information about zoning and multi-
chassis fabrics.Refer to the Switch Management manual for information about
creating zones.
Hard Zones
Hard zones provide security by allowing access only among hard zone member
devices. Access to member devices from devices outside the hard zone are
excluded. Hard zones do not overlap and take precedence over all other zone type
boundaries. Hard zones are defined by port.
Name Server Zones
Name Server zones extend access among public devices connected to fabric ports
and among private devices connected to translated loop ports. Overlapping of
Name Server zones allows the flexibility of extend the access to a specific shared
device or shared group of devices.
Within a fabric, you must choose whether to define Name Server zones by port or
by device world wide name (WWN). Name Server zoning by WWN makes it
possible for the fabric to recognize a device as a member of a Name Server zone
independent of where it is physically connected to the fabric. This can be useful
when the need arises to balance port traffic. For example, suppose there are two
public loops with one loop much busier than the other. Devices that are members
of a Name Server zone (define by WWN) can be moved from the busy loop to the
less active loop and yet be automatically recognized by the fabric.
When defining Name Server zones by WWN, it is helpful to move the chosen
devices to a switch management shelf where they can be assigned distinguishing
names. Refer to the Switch Management manual for information about naming
devices.
Segmented Loop Zones
Segmented loop zones extend access to private devices in the fabric by grouping
SL_Ports together as though they were on the same segmented loop. Segmented
loop zones are defined by port. SL_Port zones are defined by port and do not
overlap.

Rack and Shelf Administration
SANbox-16HA Fibre Channel Switch
2-22 Installation 59005-03 Rev. A Installer’s/User’s Manual
Broadcast Zones
Broadcast zones focus the distribution of broadcast messages to only those devices
that need to receive them. This reduces traffic on the fabric and eliminates unneces-
sary message processing. Broadcast zones can overlap and are also assigned by
port.
Rack and Shelf Administration
Switch management uses racks and shelves to organize the fabric topology display
for easier monitoring. A rack consists of one or more shelves. Shelves contain
switch chassis and one or more devices. The default fabric topology display shows
each switch chassis in its own rack. Any device can be moved for display purposes
to any other rack or shelf in the display. By grouping devices and naming racks,
shelves, and devices, you can create a fabric topology display that reflects how
your network functions. Refer to the Switch Management manual for more infor-
mation about rack and shelf administration.
Operating the Switch
The Power Switch and the Test Mode switch on the front of the Switch chassis are
the only operational controls. The Test Mode switch must be set to the position
shown in Figure 1-5.
The Switch becomes operational when:
• The Test Mode switch pointer is pointing straight up
• The Switch is connected to an operational power source
• The Power Switch is in the ON (1) position
• And two or more ports are cabled to their respective operational Fibre
Channel devices.

SANbox-16HA Fibre Channel Switch
3-6 Diagnostics/Troubleshooting 59005-03 Rev. A Installer’s/User’s Manual
Power-On-Self-Test (POST)
Overview
The Switch checks the state of the Test Mode switch as part of its power-up proce-
dure. Refer to Figure 3-3 for the location of the Test Mode switch.
Figure 3-1 Test Mode Switch
The normal setting of this switch (note the location of the dot on the switch relative
to the dot on the faceplate) instructs the Switch to run the diagnostics one time at
startup. If no fatal errors are encountered, the Switch places itself in normal
operating mode. The diagnostics run at startup are the Power-On-Self-Test (POST)
diagnostics.
These POST diagnostics check for proper Switch operation except for the GBICs.
During the POST, the Switch logs any errors encountered. Some POST errors are
fatal, others are non-fatal. A fatal error disables the switch so that it will not
operate. A non-fatal error allows the switch to operate, but with some decrease in
performance until the problem can be corrected.
For example:
• A PROM checksum failure is an example of a fatal error. This indicates that
the PROM firmware is corrupt and the Switch will not operate.
• A failure associated with a Fibre Channel port is an example of a non-fatal
error. The Switch can isolate the bad port, while the other ports continue to
operate.

Power-On-Self-Test (POST)
SANbox-16HA Fibre Channel Switch
Installer’s/User’s Manual 59005-03 Rev. A Diagnostics/Troubleshooting 3-7
When POST is complete and errors are encountered, the Switch uses the Heartbeat
LED to blink an error code which describes the first fatal error encountered. These
error codes are described next in this section. The Switch then reads its error log
and if it has encountered non-fatal errors that affect one or more ports (but the
remaining ports are operable) it will disable the bad ports and blink the Logged-in
LED of the affected port or ports to indicate which ports are down. If the error is
non-fatal but does not affect a single port or group of ports, only the Heartbeat
LED blinks an error code. In all cases, the Switch displays the POST error indica-
tions until you power it down.
For example:
• If the POST encounters a PROM Checksum error, the entire Switch is
inoperable. The Heartbeat LED will blink the error code for the fatal PROM
Checksum error. The entire Switch is down and no port Logged-in LEDs are
lit because the problem does not affect an individual port or ports.
• If the POST encounters a Bus error, the Switch may operate in a degraded
mode because it has multiple Buses. It can operate with one or more of them
in operation but some normal processing functions such as in-order delivery
may be adversely affected. The Heartbeat will blink the error code for the
non-fatal Bus error. The Switch may operate (a little slower) and no port
Logged-in LEDs are lit because the problem does not affect the ports.
• If the POST encounters a Port error, the Switch may operate with the remain-
ing Ports. The Heartbeat blinks an error code for the non-fatal Port error. The
Switch disables the failing port or ports and blinks their Logged-in LEDs.
The POST diagnostic program performs the following basic tests:
• checksum tests on the Boot firmware located in a PROM and the main
Switch firmware located in FLASH memory
• functional hardware tests on internal Switch memory
• various read/write register and loopback data-path tests on the Switch logic
• Frame Bus and Auto Route logic tests
NOTE:
In the following POST error descriptions you will note that some errors result in a
Switch that is operable, but in a degraded way (non-fatal errors), other errors result
in a Switch that is not operable (fatal errors).Whether the problem is fatal or non-
fatal, please contact QLogic Customer Support or your authorized maintenance
provider. If the problem is non-fatal, you should be able to run in a degraded mode
until the problem is fixed.

Heartbeat LED Blink Patterns
Normal (all pass)
If all POST diagnostics pass, the Switch will go to normal operation and the Heart-
beat LED will blink at a steady rate of one (1) blink per second.
Failure Blink Patterns
The Heartbeat LED indicates the error by blinking a series of blinks, pausing for
three seconds, then repeating the blinks. The number of blinks between the three-
second pauses indicates the error. The blinks are at about twice the speed of the
normal Heartbeat.
Test/Failure Descriptions
If any POST errors occur, notify QLogic Customer Support or your autho-
rized maintenance provider.
The following paragraphs describe the tests and their failure indication. Refer to
Appendix B QLogic Customer Support for information about how to contact
QLogic Customer Support.
PROM Checksum Failure (1 Blink)
The Switch is not operable. This is a checksum test of the PROM designed to verify
the integrity of the PROM data. A failure indicates the PROM data is corrupted
and blinks the Heartbeat LED once between three-second pauses. No port Logged-
in LEDs blink.
RAM Failure (2 Blinks)
The Switch is not operable. This is a test designed to verify the data and address
busses to the SRAM as well as the SRAM integrity. A failure indicates that either
the data bus, address bus, or SRAM is failing and blinks the Heartbeat LED twice
between three-second pauses. No port Logged-in LEDs blink.

Flash Checksum Failure/Switch Management Port (Ethernet) Tests Good (3 Blinks)
The Switch is not operable The Flash checksum test verifies the integrity of the Flash
data. If the Flash data is corrupt, the POST next checks the Switch Management
port to find out if it is functional. It does this because the Switch Management port
is the load path for loading new Flash data. If the Switch Management port tests
good, the Switch blinks the Heartbeat LED three times between three-second
pauses. No port Logged-in LEDs blink. This means that you may load new Flash
control code via the Switch Management port. Refer to the Switch Management
manual for a description of how to load new Flash code.
Flash Checksum Failure/ Switch Management port (Ethernet) Failure (4 Blinks)
The Switch is not operable. The Flash checksum test verifies the integrity of the Flash
data. If the Flash data is corrupt the POST next checks the Switch Management
port to find out if it is functional. It does this because the Switch Management port
is the load path for loading new Flash data. If the Switch Management port tests
bad, the Switch blinks the Heartbeat LED four times between three-second pauses.
No port Logged-in LEDs blink. This means that the Flash control code is corrupt
and the Switch Management port may not operate well enough to load new Flash
code.
Force PROM Mode in Effect (5 Blinks)
This is an alarm This indicates that the processor is reading the default configura-
tion from PROM instead of from Flash memory. This is due to the Test Mode
Switch being in the Force PROM position. You should never see this error in the
field if the Test mode switch is in the proper position. The Heartbeat LED will
blink five times between three-second pauses.
Switch ASIC Test Failure (6 Blinks)
The Switch is not operable. The Switch ASIC Test verifies the base functionality of
each Switch ASIC. This includes the control port interface and all functions that
can be performed within the confines of an individual ASIC. A failure indicates a
faulty Switch ASIC and blinks the Heartbeat LED six times between three-second
pauses. The Switch disables the ports associated with the bad ASIC and blinks
their Logged-in LEDs. An ASIC that fails this test could affect the operation of the
remaining ports.
GBIC Bypass Port Loopback Test Failure (7 Blinks)
The Switch is operable. The GBIC Bypass Port Loop-Back Test verifies (on a port-
by-port basis) the ability of each Switch ASIC to loop data out through the Serdes
chip on a port and back to the ASIC control port (bypassing the GBIC). A failure
indicates either a faulty Switch ASIC or an ASIC to Serdes interface problem and
blinks the Heartbeat LED seven times between three-second pauses. The Switch
disables the failing port or ports and blinks their Logged-in LEDs. The ports whose
Logged-in LEDs are not blinking have passed the test and are all usable.

Fibre Channel Port Loop-back Test Failure (8 Blinks)
This test runs in Continuous Test only. Continuous Test is controlled by the
Test Mode switch. Use this test only under the direction of QLogic Customer
Support or your authorized maintenance provider. They will tell you how to
activate this test.
The Switch is not operable while in Continuous Test. In Continuous Test mode, the
Switch Fibre Channel Port Loop-Back Test verifies the ability of each Switch ASIC
to loop data out through each Fibre Channel port, through a loopback plug, and
back to the ASIC control port. In order to accomplish this test, you must attach a
loop-back plug to each GBIC as you test it. QLogic supplies one loopback plug of
each GBIC type that you ordered. Therefore you will be able to test the GBICs one
at a time.
To test:
1. Place the chassis into Continuous Test.
2. Remove all GBICS from the chassis except the one you want to test.
The GBIC under test may be in any port. The Continuous Test will skip
all empty ports.
3. Insert a loopback plug into the GBIC.
4. Cycle the chassis power to cause a reset.
5. After a few seconds of testing, if the Heartbeat LED is blinking the
normal “heartbeat” (about once per second), the GBIC passes the test.
If the Heartbeat LED blinks the 8-blink error code, the GBIC failed.
Repeat steps 2 through 5 to test all GBICs one at a time.
6. When all tests are complete, place the Test Mode Switch back in the
“Normal Run” position (small dot on the end of the shaft pointing
straight up).
7. Cycle the chassis power to cause a reset.
Switch Bus Test Failure (9 Blinks)
The Switch may be operable. The Switch Bus Test verifies the ability of the Switch
ASICs to communicate to each other via the busses that interconnect the ASICs. A
failure indicates an inability of an ASIC pair to communicate over one or more
busses. The Switch is operable as long as at least one Frame Bus is operable.
However, some normal processing functions such as in-order delivery may be
adversely affected. A failure blinks the Heartbeat LED nine times between three-
second pauses. No port Logged-in LEDs blink.

Arbitrated Loop Test Failure (13 Blinks)
The Switch is operable. The Arbitrated Loop test verifies the ability of the Arbitrated
Loop ports to initialize properly. A failure indicates the inability to successfully
initialize an Arbitrated Loop (FL) port and blinks the heartbeat LED 13 times
between three-second pauses. The Switch disables the failing ports and blinks their
Logged-in LEDs.
The ports whose Logged-in LEDs are not blinking have passed the test and are all
usable.
Switch Management Port Failure (14 Blinks)
The Switch is operable. The Switch Management Port test verifies the integrity of the
Ethernet data bus functionality. A failure indicates that communication over the
Ethernet port will most likely be adversely affected when this failure is indicated.
The Heartbeat LED will blink fourteen times between three-second pauses. No
port Logged-in LEDs blink.
The remainder of the Switch and all ports have passed the tests and are operable.
NVRAM Test Failure (15 Blinks)
The Switch is not operable. The Non-Volatile Memory (NVRAM) test verifies the
status of the NVRAM battery (not low), performs a checksum on any existing data,
and performs a data write/read test on the unused areas of the NVRAM. A test
failure in any of the above three tests will blink the Heartbeat LED 15 times
between three-second pauses.
Hung Flash Control Code
The Switch is not operable. If the Power Good LED is lit and the Heartbeat LED and
the remaining front-panel LEDs all blink in unison, the Flash control code running

2. Slide the GBIC into the port opening (the spring-loaded door will open as
you push the GBIC in). If you can only slide the GBIC in about an inch (2.5
cm) before it stops, you have the Keyway in the wrong position; flip the
GBIC over and try it again.
3. Push the GBIC in until the GBIC Latches snap into place. If you have a
GBIC that has bail-operated latches, make sure that the bail is rotated to the
latched position. This allows the latches to latch (refer to Figure 4-4).
4. Cable the port. Refer to Section 2 Installation for cabling instructions.

Removal
If the Switch contains two Power Supplies, either supply is “Hot-Pluggable”. That
is, one supply can be removed while the Switch is powered-up and operating as
long as the other supply is operating properly.
1. Refer to Figure 4-6. Use a large flat-blade screwdriver to turn each of the two
Locking-Screws 1/4 turn counterclockwise.
2. Pull the Power Supply straight out of the back of the Switch Chassis. If the
Switch contained two power supplies and will now be operating with only
one until the second supply is replaced, install the Cover Plate over the bay. A
Cover Plate came with the Switch.

Section 5 Multi-Chassis Fabrics
Introduction
You may use SANbox Switch chassis as building blocks to build a multiple-chassis
fabric that will expand the number of user ports beyond the number in any one
chassis. Also, the cables used for interconnecting chassis in this multiple-chassis
fabric allow you to distribute the network in a campus environment, placing the
user ports near to where you need them. The actual cable length is given in
Appendix A Reference Information.
.
There are three major steps in building a multi-chassis fabric:
• Choose a topology.
• Cable the chassis into the selected topology.
• Configure the chassis and their associated user ports. Configuring the chassis
includes assigning stage types and chassis numbers. These topics are
described in this section. Configuring the user ports is the same as for a
single Switch chassis except you do it on a fabric-wide basis. These topics
are covered in the Switch Management manual.
The following paragraphs will lead you through the process of selecting a
topology, cabling the chassis, and configuring the chassis into a fabric.
NOTE:
This description assumes that all chassis are not SL Private Loop stage types. The
SL Private Loop stage type allows a reduced version of Cascade topology only.
Refer to “SL Private Loop Stage Type” on page 1-5 for more information.

Three Multi-Chassis Topologies
There are three basic multi-chassis topologies for SANbox Switches: Cascade,
Mesh, and Multistage™.
The term “cascade” indicates that chassis are connected in a row “one-to-the-
next”. You may optionally have chassis interconnections from the last chassis back
to the first chassis. Any port on a SANbox chassis that is placed in a cascade
topology can be either a user port (a port connected to users) or a T_Port
(connected to other Switch chassis). Connect any SANbox port to another Switch
and the port configures itself as a T_Port. All chassis in a cascade topology have a
Stage Type of Input-Output/Transfer (IO/T) or SL Private Loop.
The default is IO/T.
The term “mesh” indicates that each chassis has at least one T_Port directly
connected to each other chassis (each chassis connected to each other chassis).
Any port on a SANbox chassis that is placed in mesh topology can be either a user
port (connected to users) or a T_Port (connected to other Switch chassis). Connect
any SANbox port to another Switch and the port configures itself as a T_Port. All
chassis in a mesh topology have a Stage Type of Input-Output/Transfer (IO/T). The
default is IO/T.
A Multistage Switch consists of chassis configured in two different stage types, an
Input-Output/Transfer (IO/T) stage type, and a Cross-Connect (CC) stage type.
Two or more chassis with the IO/T stage type supply user ports to connect to the
users, and T_Ports that connect to one or more chassis with the CC stage type. The
chassis with the CC stage type supply interconnections for the T_Ports. Any
SANbox chassis can function as an IO/T stage type or as a CC stage type. Switch
management allows you to designate the stage type of any chassis as IO/T or CC.
The default stage type for any chassis is IO/T. Connect any port on a chassis with
an IO/T stage type to another chassis and the port configures itself as a T_Port. All
ports on a CC stage type are T_Ports
NOTE:
Use your SANbox Switch chassis in any of these topologies, but do not mix the
topologies in the same fabric. That is, use your chassis in a Cascade, or Mesh,
or Multistage but do not use a combination of topologies in the same fabric.

Introduction
SANbox-16HA Fibre Channel Switch
Installer’s/User’s Manual 59005-03 Rev. A Multi-Chassis Fabrics 5-3
Choosing a Topology
The topology you choose depends on the following major fabric requirements:
• The size of the fabric (number of user ports required),
• The amount of latency the users can tolerate (number of chassis hops and
interconnection media delay between the source port and the destination
port),
• The bandwidth between chassis (the number of T_Port paths between inter-
connected chassis),
• The physical distances required between users in a “campus” distributed
fabric verses a centrally located fabric.
• MKII compatibility. SANbox switch fabrics support MKII switches as IO/T
chassis in mesh and Multistage topologies.
These topics are discussed for each topology later in this section.
NOTE:
In order to set up a multi-chassis fabric you are required to select a topology, cable
the chassis together, and configure each chassis.
Configuration consists of assigning a stage type to a chassis which tells it which
function it is to perform (IO/T or CC). In the case of a Cascade or Mesh topology,
all chassis are the default stage type (IO/T). A Multistage switch consists of IO/T
and CC chassis. For addressing purposes, you must also assign a Chassis Number
to each chassis.
Refer to“Cascade Topology” on page 5-5, “Mesh Topology” on page 5-9, and
“Multistage Topology” on page 5-12 for information about choosing a fabric
topology. After choosing the fabric topology, refer to “Cabling” on page 5-17 and
“Chassis Configuration” on page 5-18 for the remaining instructions.

Introduction
SANbox-16HA Fibre Channel Switch
5-4 Multi-Chassis Fabrics 59005-03 Rev. A Installer’s/User’s Manual
Bandwidth Between Chassis
Each T_Port link between directly connected chassis contributes 100 megabytes of
bandwidth between those chassis. Devoting half of the chassis ports to T_Ports
may provide as much bandwidth between directly connected chassis as there is to
user ports on the chassis (no bottleneck between chassis). One T_Port interconnec-
tion between chassis is the minimum.
Fabric topology also affects bandwidth between chassis. In Mesh and Cascade
topologies, T_Ports are either distributed between adjacent chassis (Cascade
topology) or distributed among all chassis (Mesh Topology). Thus, in these topolo-
gies, the bandwidth is also distributed (divided among chassis).
In Multistage topology, all bandwidth is fully maintained between IO/T chassis. It
is therefore possible, in Multistage topology, to provide as much as 400 MBytes
per second bandwidth between any two 8-port IO/T chassis.
Cable Length
The maximum cable length between chassis depends on the type of interconnect
media (GBICs).
In Order Delivery
SANbox Switch chassis guarantee in order delivery with any number of T_Port
links between chassis.
Zoning in a Multi-Chassis Switch
SANbox Switch chassis support fabric-wide zones for all zone types. Broadcast,
and Name Server zones require no special consideration in a multi-chassis fabric.
T_Ports are not zoned.
Hard Zones, however, require zoned T_Port interconnections between chassis
which contain ports in the same Hard Zone. That is, if a particular Hard Zone is
distributed across chassis boundaries, each piece of that Hard Zone and its inter-
connecting T_Ports must be assigned to the same Hard Zone number. This makes
interconnections between pieces of the same Hard Zone much like the interconnec-
tion of chassis.
NOTE:
• Mixing of topologies is not allowed. If the topology of the chassis is Multi-
stage, then the interconnection of the Hard Zones must also be accomplished
in Multistage topology.
• Hard zoning and Name Server zoning by world wide name (WWN) are not
supported for SANbox/MKII fabrics.

Cascade Topology
The term “cascade” indicates that chassis are connected in a line “one-to-the-
next”. You may optionally have chassis interconnections from the last chassis back
to the first chassis (Loop). The loop provides better latency because any chassis can
route traffic in the shortest direction to any another chassis in the loop. The loop
also provides failover when only one chassis interconnection is used. Figure 5-1
shows an example of Cascade-with-a-loop interconnection.
Figure 5-1 Cascade Example
In fabrics containing two or three chassis, Cascade-with-a-loop topology and Mesh
topology are exactly the same. Note in Figure 5-1 that if the fabric contained only
three chassis and the loop back to the first chassis came from chassis 3, that each
chassis would be directly connected to each other chassis which is the definition of
Mesh topology.

Cascade Fabric Size
SANbox-16 chassis connected in Cascade topology expand from two chassis to a
maximum of eight chassis. If you use Cascade-with-a-loop topology and cable
eight T_Ports on each chassis for chassis interconnection (four to each adjacent
chassis), this results in a maximum of 64 user ports. If you cable two T_Ports on
each chassis for chassis interconnection (one to each adjacent chassis), this results
in a maximum of 112 user ports.
If your fabric port requirements dictate the use of eight or more Switch chassis,
Multistage topology can result in more user ports than Cascade-with-a-loop
topology. Multistage topology is described later in this manual.
Cascade Latency
Each Chassis will route traffic in the direction of the least number of chassis hops.
A chassis will route traffic in the other direction if all links in the closest direction
fail.
Latency to any port on the same chassis is one chassis hop.
Latency to any port on adjacent chassis is two chassis hops (counting the source
chassis). This is the same latency as Mesh and better than Multistage. Multistage
has three hops to any other IO/T chassis.
Latency to any port on the second chassis away in either direction is three chassis
hops. This is worse than Mesh (for latency purposes, all chassis in Mesh are
adjacent chassis) and the same as Multistage.
Latency to any port on the third chassis away in either direction is four chassis
hops. This is worse than Mesh (for latency purposes, all chassis in Mesh are
adjacent chassis). At this point, a Multistage switch has less latency (three hops to
any chassis).
As you can see from the above, latency becomes more costly than other topologies
beyond five cascaded chassis. At five chassis, no destination is more than three
chassis hops away in the shortest direction (counting the source chassis).

Cascade Topology
SANbox-16HA Fibre Channel Switch
Installer’s/User’s Manual 59005-03 Rev. A Multi-Chassis Fabrics 5-7
Cascade Bandwidth
A chassis in a Cascaded topology divides its chassis interconnection bandwidth
between adjacent chassis. That is, half of the T_Ports connect one direction around
the loop and the other half connect the other direction around the loop. Even if you
cable half of the chassis ports to T_Ports, you will only have one quarter of the
chassis bandwidth connected in the direction of the least number of chassis hops to
the destination chassis. Each Chassis will route traffic in the direction of the least
number of chassis hops to the destination chassis. A chassis will route traffic in the
other direction only if all links in the closest direction fail.
Also, traffic destined for any port NOT on the same chassis as the source port will
be sharing the interconnection bandwidth with any other ports on other chassis that
need to communicate over those same chassis links.
In fabrics of two or three chassis, Mesh and Cascade-with-a loop topologies are the
same for purposes of bandwidth. For fabrics of four or more chassis, Mesh
topology must use only one T_Port connected to each other chassis in the fabric
because if you used two or more from each chassis you would use up too many
ports to interconnect the chassis. Thus, cascaded connections may result in better
bandwidth than Mesh.
Multistage topology has the best bandwidth. All T_Ports from each IO/T chassis
connect (through the CC chassis) to all other IO/T chassis in the same number of
chassis hops (three) no matter how large the fabric is. Thus the useful interconnec-
tion bandwidth from each IO/T chassis increases by 100MBs per T_Port. It is
possible in Multistage topology to devote half of the chassis bandwidth to T_Ports
thus providing as much as 800 MBytes per second bandwidth between any two
IO/T chassis.
Cascade Physical Distance between Chassis
Cascade topology can cover the largest campus area relative to other topologies. A
cascaded topology can be laid out in a loop with the distance between adjacent
chassis equal to or less than the maximum cable length of the installed GBICs.

Cascade Zoning
Sanbox Switch chassis support fabric-wide zones for all zone types. Broadcast
Zones and Name Server Zones require no special consideration in a cascade fabric.
That is, you may assign these zones on a user-port-by-user-port basis and T_Ports
are not zoned.
Hard Zones, however, require zoned T_Port interconnections between chassis
which contain ports in the same Hard Zone. That is, if a particular Hard Zone is
distributed across chassis boundaries, each piece of that Hard Zone and its inter-
connecting T_Ports must be assigned to the same Hard Zone number. This makes
interconnections between pieces of the same Hard Zone much like the interconnec-
tion of chassis.
MKII Compatibility
SANbox fabrics do not support MKII chassis in cascade topologies.
NOTE:
Also, remember that mixing of topologies is not allowed. If the topology of the
chassis is Cascade, then the interconnection of the Hard Zones must also be
accomplished in Cascade topology.

Mesh Topology
The term “mesh” indicates that each chassis has at least one T_Port directly
connected to each other chassis.
In fabrics containing two or three chassis, Cascade-with-a-loop topology and Mesh
topology are exactly the same. Note in Figure 5-2 that you could take any three
chassis and their interconnections and draw them in a row with a loop back from
the last chassis to the first chassis (the same as Cascade-with-a-loop).
Figure 5-2 Mesh Example
Mesh Fabric Size
SANbox-16 chassis connected in Mesh topology expand from two chassis to a
maximum of nine chassis. With each chassis using eight T_Ports for chassis inter-
connection, then each chassis will have 8 user ports remaining. Figure 5-2 shows
an example of mesh interconnections.
Using four to eight chassis, Cascade-with-a-loop topology can result in more user
ports than Mesh topology.
Using six or more chassis, Multistage topology can result in more user ports than
Mesh topology. Multistage topology is described later in this manual.
Mesh Latency
Each Chassis will route traffic through the path of the least number of chassis hops
to the destination chassis. A chassis will route traffic through other paths only if all
links in the closest direction fail.
Latency to any port on the same chassis is one chassis hop.
Latency to any port on any other chassis is two chassis hops (counting the source
chassis). This is the same latency as two or three chassis connected in Cascade -
with-a-loop. It is better than Multistage. Multistage has three hops to any IO/T
chassis.
Preliminary
Mesh Topology

5-10 Multi-Chassis Fabrics 59005-03 Rev. A Installer’s/User’s Manual
Mesh Bandwidth
A chassis in a Mesh topology divides its chassis interconnection bandwidth among
the other chassis in the fabric. That is, each chassis has at least one T_Port connec-
tion to each other chassis in the fabric. In small fabrics of two or three chassis, you
could have two or more connections to each other chassis. In fabrics of four or five
chassis you should connect only one T_Port to each other chassis. Otherwise you
will use more than half of your ports as T_Ports. Each Chassis will route traffic
through the path of the least number of chassis hops to the destination chassis. A
chassis will route traffic through another path if all links in the closest path fail.
In fabrics of two or three chassis, Mesh and Cascade-with-a loop may be the same
for purposes of bandwidth.
Multistage topology has the best bandwidth. All T_Ports from each IO/T chassis
connect to all other IO/T chassis in the same number of chassis hops (three) no
matter how large the fabric is. Thus the useful interconnection bandwidth from
each IO/T chassis increases by 100MBs per T_Port. It is therefore possible, in
Multistage topology, to provide as much as 800 MBytes per second bandwidth
between chassis.
Mesh Physical Distance Between Chassis
Mesh topology can be laid out in an area where the distance between any two
chassis is equal to or less than the maximum cable length of the installed GBICs.
Both Cascade-with-a-loop and Multistage topologies can produce larger areas.

Mesh Zoning
Sanbox Switch chassis support fabric-wide zones for all zone types. Broadcast
Zones and Name Server Zones require no special consideration in a mesh fabric.
That is, you may assign these zones by port or by device. T_Ports are not zoned.
Hard Zones, however, require zoned T_Port interconnections between chassis
which contain ports in the same Hard Zone. That is, if a particular Hard Zone is
distributed across chassis boundaries, each piece of that Hard Zone and its inter-
connecting T_Ports must be assigned to the same Hard Zone number. This makes
interconnections between pieces of the same Hard Zone much like the interconnec-
tion of chassis.
MKII Compatibility
SANbox switch fabrics support MKII chassis in mesh topologies of up to five
chassis. All chassis in a SANbox/MKII mesh fabric support only one active T_Port
between any two chassis, though more may be connected. Hard zoning and Name
Server zoning by WWN are not supported in SANbox/MKII fabrics.
NOTE:
Also, remember that mixing of topologies is not allowed. If the fabric topology
is Mesh, then the interconnection of the Hard Zones must also be accom-
plished in Mesh topology.
Preliminary
Multistage Topology
SANbox-16HA Fibre Channel Switch
5-12 Multi-Chassis Fabrics 59005-03 Rev. A Installer’s/User’s Manual
Multistage Topology
A Multistage Switch consists of chassis configured in two different Stage Types, an
Input-Output/Transfer (IO/T) stage type, and a Cross-Connect (CC) Stage Type.
Two or more chassis with the IO/T Stage Type supply user ports to connect to the
users, and T_Ports that connect to one or more chassis with the CC Stage Type. The
chassis with the CC Stage Type supply interconnections for the T_Ports. Any
SANbox chassis can function as an IO/T Stage Type or as a CC Stage Type. Switch
management allows you to designate the Stage Type of any chassis as IO/T or CC.
The default Stage Type for any chassis is IO/T.
T_Port Rules for SANbox IO/T Chassis
Any port on a SANbox-8 or 16 IO/T chassis may be a T_Port. T_Ports are used to
interconnect chassis and are not user ports. QLogic suggests that you not use more
than half of the ports on a chassis as T_Ports. Chassis numbers must be unique
among all IO/T chassis in a fabric. If there is a chassis number conflict, the switch
with the higher world wide name will be disabled. In addition, a Logged-In LED
on the switch with the lower world wide name will blink to indicate which port is
connected to the conflicting switch.
You must connect at least one T_Port on each IO/T chassis to each CC chassis.
T_Port Rules for SANbox Cross-Connect (CC) Chassis
All ports on a SANbox CC chassis are T_Ports. As T_Ports they are used to inter-
connect chassis and are not user ports. Chassis numbers must be unique among all
CC chassis in a fabric. If there is a chassis number conflict, the switch with the
higher world wide name will be disabled. In addition, a Logged-In LED on the
switch with the lower world wide name will blink to indicate which port is
connected to the conflicting switch. Each CC chassis must have at least one T_Port
connection from each IO/T chassis.
Multistage Fabric Size
SANbox-16 chassis connected in Multistage topology (All SANbox-16 chassis)
expand from three chassis to a maximum of 17 to 24 chassis (16 IO/T chassis and
one to eight CC chassis). This results in 128 to 240 user ports depending on the
number of T_Ports used to interconnect the chassis.
Multistage Latency
Latency between any two user ports on different chassis is three chassis hops
(counting the source and destination chassis).

Multistage Bandwidth
Multistage topology has the best bandwidth. All T_Ports from each IO/T chassis
connect to all other IO/T chassis in the same number of chassis hops (three) no
matter how large the fabric is. Thus the useful interconnection bandwidth from
each IO/T chassis to any other IO/T chassis increases by 100MBs per T_Port. It is
possible in Multistage topology to devote half of the chassis bandwidth to T_Ports
thus providing as much as 800 MBytes per second bandwidth between any two IO/
T chassis.
Multistage Physical Distance Between Chassis
You may locate the CC chassis in the center of a circle with a radius of the
maximum cable length allowed by the selected GBICs and interconnection media.
Multistage Zoning
Sanbox Switch chassis support fabric-wide zones for all zone types. Broadcast
Zones and Name Server Zones require no special consideration in a Multistage
fabric. That is, you may assign these zones by port or by device. T_Ports are not
zoned.
Hard Zones, however, require zoned T_Port interconnections between chassis
which contain ports in the same Hard Zone. That is, if a particular Hard Zone is
distributed across chassis boundaries, each piece of that Hard Zone and its inter-
connecting T_Ports must be assigned to the same Hard Zone number. This makes
interconnections between pieces of the same Hard Zone much like the interconnec-
tion of chassis.
MKII Compatibility
SANbox switch fabrics support MKII chassis in Multistage topologies. The MKII
switches should be used only as IO/T chassis, while the SANbox switches can be
IO/T or cross-connect chassis. All chassis in a SANbox/MKII Multistage fabric
support only one active T_Port between any two chassis, though more may be
connected. Hard zoning and Name Server zoning by WWN are not supported in
SANbox/MKII fabrics.
NOTE:
Also, remember that mixing of topologies is not allowed. If the topology of the
chassis is Multistage, then the interconnection of the Hard Zones must also be
accomplished in Multistage topology.

T_Port/CC that is good.
Note that any IO/T chassis can communicate with any other IO/T chassis with just

Cabling
Any port on an IO/T chassis may be a T_Port. If you are using 2, 3, or 4 T_Ports on
each chassis, it is best to distribute these T_Ports as evenly as possible between the
ASIC port groups on each IO/T chassis. That is, don’t bunch the T_Ports up in one
ASIC port group. See “Tuning” on page 2-9 for more information about ASIC port
groups. Using a port as a T_Port does not affect any other port on the chassis.
Fiber Optic T_Port Connections
If you have individual connectors (one for each fiber), connect the transmit side of
the T_Port on one chassis to the receive side of the T_Port on the other chassis.
Connect the receive side of the T_Port on one chassis to the transmit side of the
T_Port on the other chassis. On the top row of ports on a chassis, the transmit
connector is the right-hand connector of each pair. On the bottom row of ports on a
chassis, the transmit connector is the left-hand connector of each pair. Refer to
Section 1 General Description for a drawing showing the transmit and receive
connectors in a port serviced by a fiber optic GBIC.
Keys on “Duplex” cable assemblies (a connector-pair containing both transmit and
receive together in one unit), prevent you from connecting them incorrectly.
Copper T_Port Connections
HSSDC and DB-9 connectors are duplex cable assemblies. That is, both the
transmit and receive contacts are part of the same keyed plug assembly. You can’t
plug them in wrong.
T_Port Cable Length
The maximum cable length between chassis depends on the type of interconnec-
tion media and its associated GBICs. Refer to Appendix A Reference Information
for the various types of interconnection media and GBICs.
Device Connections
Cable the user ports to their respective node devices. User ports are all those ports
on an IO/T chassis that are not used as T_Ports. User ports may be F, FL, SL, or
TL_Ports. Try to localize the traffic to each chassis as much as possible to
minimize the amount of traffic across the T_Port links between chassis.
Preliminary
Chassis Configuration
SANbox-16HA Fibre Channel Switch
5-18 Multi-Chassis Fabrics 59005-03 Rev. A Installer’s/User’s Manual
Chassis Configuration
There are two parameters that control the role that each chassis plays in a multi-
chassis fabric: Stage Type and Chassis Number.
Assign the Stage Type and Chassis Number for the selected chassis using the
SANsurfer Switch management application. Refer to“Chassis Configuration
Process” on page 5-19 for an explanation of this process.
SANsurfer can manage multiple chassis within a fabric through a single Ethernet
connection to any one chassis in the fabric. First however, before the fabric can be
managed using the Ethernet port, several management parameters must be set
correctly on the chassis with the Ethernet connection. At a minimum, the IP
network address, the IP subnetwork mask, and the IP gateway address must all be
set. In addition, the SNMP read, write, and trap community names may be set, as
well as the SNMP name, contact, and location. This setup is required only for the
chassis that is directly connected to the Ethernet network.
The major steps in this process are:
1. Physically connect a management station directly to the Ethernet port of
chassis through which the fabric will be managed.
2. Configure the Ethernet Port of the Switch chassis through which the fabric
will be managed.
3. Configure the Stage Type and Chassis Number of each Chassis in the Fabric.
The instructions in this section assume that you are starting with SANbox chassis
that have never had their Ethernet ports connected to a management station. In
other words, this section starts from the beginning.
You may have chassis that have been managed via the SANsurfer Switch manage-
ment application. In this case you may not need to start at the beginning.
NOTE:
This process assumes that chassis are cabled together in a cascade, mesh, or Multi-
stage topology.
Preliminary
Chassis Configuration Process
SANbox-16HA Fibre Channel Switch
Installer’s/User’s Manual 59005-03 Rev. A Multi-Chassis Fabrics 5-19
Chassis Configuration Process
1. Physically Connect a Management Station directly to the Ethernet port of the
chassis through which the fabric will be managed.
Follow the Ethernet Cabling instructions in the Switch Management manual
to install the Switch (any Switch chassis in the fabric) temporarily on an
isolated Ethernet network with the subnet address 10.x.x.x (By default, the
Switch’s IP address is 10.0.0.1.). This network does not need to contain
anything more than the Switch (the Switch, in turn, could be cabled to the
rest of the chassis via its T_Ports) and a single management host to configure
the Switch. You may then use the SANsurfer Switch management application
to configure the Switch chassis’ Ethernet port.
2. Configure the Ethernet Port of the Switch chassis through which the fabric
will be managed.
Refer to Switch Management manual for information about how to start
SANsurfer, how to select the chassis whose Ethernet port you want to config-
ure, and how to configure the Ethernet Port. You need to configure the Ether-
net port of only one chassis in the fabric. You could configure another chassis
for backup.
You must reset the Switch chassis to cause it to use its new IP Address. Reset
the Switch chassis by cycling its power or using Switch Management.
Following the reset operation you may move the Ethernet connection to the
Switch chassis from its temporary isolated network to its normal Ethernet
network.
3. Configure the Stage Type and Chassis Number of each Chassis in the Fabric.
If you have moved to a new management station at this point you must follow
the Getting Started paragraphs in SANsurfer section of the Switch Manage-
ment manual to open the application and get back to the Fabric window.
If you are still using the same management station as you used to configure
the Ethernet IP Address, get back to the Fabric window.
a. The Fabric window will show the fabric you created in order to
configure the Ethernet connection. You may create a new fabric with a
new Fabric Name and the new IP Address or you may modify the old
fabric by changing its fabric name and IP Address.
b. Double-click the Fabric Icon in the Status Field. The application will
connect to the fabric with its new IP Address and jump to the Topology
window.
Preliminary
Chassis Configuration Process
SANbox-16HA Fibre Channel Switch
5-20 Multi-Chassis Fabrics 59005-03 Rev. A Installer’s/User’s Manual
c. The Fabric Topology window will display all the Switch chassis in the
fabric and show the T_Port interconnections. Initially, all chassis will
be IO/T chassis. Double click a chassis that you want to configure. The
application will jump to the Switch Faceplate display for the selected
Switch chassis.
d. Just below the faceplate is the Chassis Parameters/Switch Statistics
area. Change the Stage Type to FLS-Cross-Connect (if it is a CC
chassis), assign the chassis a Chassis Number (unique within each
Stage Type), and press Apply. Chassis Numbers are in the range of 0 to
63 and must be unique within each Stage Type. The Default is zero.
e. Press the Back button to return to the Fabric Topology window. The
application will poll the fabric for its new configuration (it takes about
15 seconds to poll the fabric). The Topology window will use the switch
color to show that the chassis you changed is now a CC.
f. Repeat steps c, d, and e for each chassis in the fabric.
NOTE:
• If two switches of the same stage type have the same chassis number,
the switch with the higher world wide name will be disabled. In
addition, the affected Logged-In LEDs on both chassis will blink to
indicate that a conflict exists.
• When adding a switch to an active fabric, be sure that the new switch
has a unique chassis number. A chassis number conflict could disable a
single IO/T chassis or, in the case of a CC chassis, an entire fabric.
NOTE:
The fabric is now a multi-chassis fabric and you may proceed to configuring
the user ports if necessary. Configure user ports and zones with the Switch
management application.
