SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
THE FE-100F3 FAST ETHERNET INTERFACE MODULE USES CLASS
1 LASER TRANSCEIVERS. READ THE FOLLOWING SAFETY
INFORMATION BEFORE
INSTALLING OR OPERATING THESE MODULES.
The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This
control loop eliminates the need for maintenance checks or adjustments. The output is factory set, and
does not allow any user adjustment. Class 1 Laser transceivers comply with the following safety
standards:
• 21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).
• IEC Publication 825 (International Electrotechnical Commission).
• CENELEC EN 60825 (European Committee for Electrotechnical Standardization).
When operating within their performance limitations, laser transceiver output meets the Class 1
accessible emission limit of all three standards. Class 1 levels of laser radiation are not considered
hazardous.

SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
LASER RADIATION AND CONNECTORS
When the connector is in place, all laser radiation remains within the fiber. The maximum amount of
radiant power exiting the fiber (under normal conditions) is -12.6 dBm or 55 x 10-6 watts.
Removing the optical connector from the transceiver allows laser radiation to emit directly from the
optical port. The maximum radiance from the optical port (under worst case conditions) is
0.8 W cm-2 or 8 x 103 W m2 sr-1.
Do not use optical instruments to view the laser output. The use of optical instruments to view
laser output increases eye hazard. When viewing the output optical port, power must be
removed from the network adapter.

6H12X-08 Overview

1.3

6H12X-08 OVERVIEW

The 6H12X-08 (the 6H128-08 is shown in Figure 1-1) is a Fast Ethernet
interface module for the Cabletron Systems 6C105 chassis. The module
has six switched fiber optic ports and two optional ports for Fast Ethernet
Interface Modules.
The 6H128-08 has six multimode fiber optic 100BASE-FX switched
ports using SC connectors, while the 6H129-08 has six single mode fiber
optic 100BASE-FX switched ports also using SC connectors.
The 6H12X-08 supports IEEE 802.1D switching (bridging), Port Based
VLANs (IEEE 802.1Q), and Cabletron Systems SecureFast Switching
Virtual Network technology. The 6H12X-08 is used to connect individual
high-bandwidth user devices, such as workstations, and to provide a
central switching point for multiple 10/100 Mbps Fast Ethernet segments.

1.3.1

Connectivity

The 6H12X-08 connects to Ethernet networks or workstations through six
fiber optic ports with SC connections on the front panel. The 6H128-08
supports multimode fiber SC ports, and the 6H129-08 supports single
mode fiber SC ports. The multimode ports are IEEE 802.3u 100BASE-FX
compliant.
The 6H12X-08 has two front panel slots (ports 7 and 8) for optional Fast
Ethernet Interface Modules (FE-100TX, FE-100FX, and FE-100F3) to
support an uplink to 100 Mbps Fast Ethernet backbones or a high speed
connection to a local server using twisted pair, multimode or single mode
fiber optic cabling.

1.3.2

Full Duplex Switched Ethernet (FDSE)

Each switched Fast Ethernet port on the 6H12X-08 supports 100 Mbps
operation and can be configured to operate in Full Duplex Switched
Ethernet (FDSE) mode. FDSE allows each Fast Ethernet port to provide
up to 200 Mbps of throughput.

1.3.3

Runtime IP Address Discovery

This feature enables the 6H12X-08 to automatically accept an IP address
from a BootP server on the network into NVRAM without requiring a
user to enter an IP address through Local Management.
When the 6H12X-08 is connected to the network and powered up,
Runtime IP Address Discovery (RAD) checks the 6H12X-08 for an IP
address. If one has not been assigned (6H12X-08 IP address set to
0.0.0.0), RAD checks to see if any of the 6H12X-08 interfaces have a
link. If so, RAD sends out Reverse Address Resolution Protocol (RARP)
and BootP requests to obtain an IP address from a BootP or RARP server
on the network.
The RAD requests start out at an interval of 1 second and doubles after
every transmission until an interval of 300 seconds is reached. At this
point, the interval remains at 300 seconds. The RAD requests continue
until an IP address is received from a BootP or RARP server, or an IP
address is entered using Local Management.

1.3.4

Management

Management of the 6H12X-08 is accomplished using Local Management
tools or remote Simple Network Management Protocol (SNMP)
management stations. In-band remote management is possible using any
SNMP compliant Network Management Software. Out-of-band Local
Management is provided through the RJ45 COM port on the front panel
using a VT100 terminal, or a remote VT100 terminal emulator via a
modem connection, and in-band via a Telnet connection.
Local Management provides the ability to manage the 6H12X-08 and any
of the optional Fast Ethernet Interface Modules installed in ports 7 and 8
of the 6H12X-08.

1.3.5

Remote Monitoring (RMON)

The 6H12X-08 supports all Ethernet RMON groups, which include
Statistics, Alarms, Events and History. These groups are enabled on all
ports by default.
Cabletron Systems RMON Actions is a vendor specific extension of
RMON and provides the ability to set an “Action” on any SNMP MIB
variable. The Action can be triggered by any RMON Event and/or Alarm.
The Action can be, for example, to turn a MIB-2 interface off if a
broadcast threshold is crossed.

1.3.6

Switching Options

The 6H12X-08 provides IEEE 802.1D switching, IEEE 802.1Q, or
SecureFast Switching Virtual Network Services between all of the front
panel interfaces including Fast Ethernet Interface Modules. SecureFast
Switching and IEEE 802.1Q allow for migration to Virtual Network
technologies without requiring the replacement of existing equipment.

1.3.7

Standards Compatibility

The 6H12X-08 meets 802.3u specifications, and provides IEEE 802.1D
and DEC Spanning Tree Algorithm (STA) support to enhance the overall
reliability of the network and protect against “loop” conditions. The
6H12X-08 supports a wide variety of industry standard MIBs including
RFC 1213 (MIB II), RFC 1757 (RMON), RFC 1371 (RS232 MIB),
RFC 1493 (Bridge MIB) and RFC 1354 (FIB MIB). A full suite of
Cabletron Systems Enterprise MIBs provide a wide array of statistical
information to enhance troubleshooting.

1.3.8

Year 2000 Compliant

The 6H12X-08 has an internal clock that can maintain the time and date
beyond the year 1999.

Local Management Features

1.3.9

LANVIEW Diagnostic LEDs

The various conditions of the LANVIEW diagnostic LEDs serve as
important troubleshooting aids. They provide an easy way to observe the
transmit and receive status of individual ports and overall network
operations such as system status, switching configuration, and Fast
Ethernet channel usage. Chapter 4 provides details about the 6H12X-08
LANVIEW LEDs.

1.4

LOCAL MANAGEMENT FEATURES

Local Management provides the tools that allow management of the
6H12X-08, any installed Fast Ethernet Interface Modules, and the 6C105
chassis, using SNMP compliant management tools.

1.4.1

Broadcast Suppression

Broadcast Suppression allows a user to set a desired limit of receive
broadcast frames per port/per second to be forwarded out the other ports
on the module up to the set limit. Any broadcast frames above this
specified limit are dropped. In the event that broadcast frames are being
suppressed, multicast and unicast frames continue to be switched.

1.4.2

Port Redirect Function

The port redirect function, also referred to as “Port Mirroring,” is a
troubleshooting tool used to map traffic from a single source port or
multiple source ports to a destination port(s) within the chassis. This
feature functions at the bit level, which allows all packets, including those
with errors, to be copied and sent to an analyzer or RMON probe. The
analyzer or RMON probe will see the data as if it is directly connected to
the LAN segment of the source port(s).

1.4.3

Distributed Chassis Management

From a management perspective, the 6C105 SmartSwitch 6000 chassis
can be viewed as a single entity with a single IP address. Its management
functions are distributed to all modules. This means a single module in
the chassis, such as the 6H12X-08, can be used to manage the entire
chassis, and any other attached module through Local Management,
SNMP, or Telnet applications.

1.4.4

SmartTrunk

SmartTrunk, also referred to as SmartTrunking, is Cabletron Systems’
terminology for load balancing or load sharing. SmartTrunk technology
provides an easy-to-implement mechanism to group, or aggregate,
multiple physical links together to scale the backbone bandwidth beyond
the limitations of a single link. All links are user-configurable so
administrators can scale the backbone bandwidth by adding SmartTrunk
links. The SmartTrunk benefits are as follows:
•

All purchased bandwidth is used.

•

Distributed, resilient links increase reliability and performance.

•

Multiple technologies are supported within a single trunk for
maximum flexibility.

For more information about SmartTrunk, refer to the Cabletron Systems
SmartTrunk User’s Guide.

1.5

OPTIONAL FEATURES

Options for the 6H12X-08 include Fast Ethernet Interface Modules to add
additional interface capability.
Cabletron Systems provides Fast Ethernet Interface Modules to support
uplinks to 100 Mbps Ethernet backbones or high speed connections to
servers. The Fast Ethernet Interface Modules are listed in Table 1-1.

(APC) Uninterruptible Power Supply (UPS) device for protection against
the loss of power, a connection from the 6H12X-08 COM port to the UPS
can be made to monitor the power status of the UPS. To use the COM port
for this purpose, it must be reconfigured to support the UPS connection
using the procedure described in Section 5.15.11. Refer to the UPS
documentation for details on how to access the status information.
The Console Cable Kit provided with the 6H12X-08 is used to attach the
UPS to the 6H12X-08 COM port as shown in Figure 5-2.
To connect the UPS device to the COM port of the 6H12X-08, proceed as
follows:
1. Connect the RJ45 connector at one end of the cable to the COM port
on the module.
2. Plug the RJ45 connector at the other end of the cable into the
RJ45-to-DB9 male (UPS) adapter, Cabletron Systems Part No.
9372066.
3. Connect the RJ45-to-DB9 male (UPS) adapter to the female DB9 port
on the rear of the UPS device (see the particular UPS device’s user
instructions for more specific information about the monitoring
connection).

MAC Address (Read-Only)

Displays the physical address of the chassis.
IP Address (Modifiable)

This field allows the IP address to be set for the 6C105 chassis. If an IP
address is assigned to the 6C105 chassis all the interface modules
installed in the chassis can be managed via this IP address, eliminating the
need to assign an IP address to each interface module. To set the IP
address, refer to Section 5.7.1.

Subnet Mask (Read-Only)

NOTE

When a valid IP address is assigned, the Subnet Mask field
automatically enters the default mask that corresponds with the
class of IP entered in the IP Address field. Some firmware
revisions do support changing the chassis subnet mask from
the default value. Refer to the Release Notes to ensure that the
Subnet Mask is a modifiable field.

Displays the subnet mask for the chassis. A subnet mask “masks out” the
network bits of the IP address by setting the bits in the mask to 1 when the
network treats the corresponding bits in the IP address as part of the
network or subnetwork address, or to 0 if the corresponding bit identifies
the host. The 6C105 chassis automatically uses the default subnet mask
that corresponds to the IP class that was entered in the IP address field.
For details about how to change the Subnet Mask from its default value,
refer to Section 5.7.2.
Chassis Date (Modifiable)

Contains a value that the chassis recognizes as the current date. When the
chassis date is modified and saved all interface modules installed in the
chassis are set to this date. To set a new chassis date, refer to
Section 5.7.3.
Chassis Time (Modifiable)

Contains a value that the chassis recognizes as the current time. When the
chassis time is modified and saved, all interface modules installed in the
chassis are set to this time. To enter a new time, refer to Section 5.7.4.
Screen Refresh Time (Modifiable)

Contains the rate at which the screens are updated. This setting
determines how frequently (in seconds) information is updated on the
screen. To enter a new update time, refer to Section 5.7.5.

Chassis Configuration Screen
Screen Lockout Time (Modifiable)

Contains the maximum number of minutes that the Local Management
application displays a module’s screen while awaiting input or action
from a user. For example, if the number 5 is entered in this field, the user
has up to five minutes to respond to each of the specified module’s Local
Management screens. In this example, after five minutes of “idleness” (no
input or action), the terminal “beeps” five times, the Local Management
application terminates the session, and the display returns to the Password
screen. To enter a new lockout time, refer to Section 5.7.6.
Chassis Uptime (Read-Only)

Displays the total time the chassis has been operating. The chassis uptime
is based on which interface module installed in the chassis has been
operating for the longest period of time.
Operational Mode (Toggle)

This field allows the user to set all the modules in the chassis to operate as
traditional switches (802.1D SWITCHING option), or as IEEE 802.1Q
switches (802.1Q SWITCHING option).
In 802.1D SWITCHING mode, the six ports located on the front panel
and each optional Fast Ethernet Interface Module are bridged to each
other.
When the operational mode is set to 802.1Q SWITCHING, the
6H12X-08 acts as an IEEE 802.1Q switch. The modules are able to
increase their switching functionality by creating and maintaining port
based Virtual LANs (VLANs).
This field will display the existing status of the chassis the first time the
screen displays. If modules in the chassis are set to different operational
modes, then the first time this field displays, it will display “MIXED
MODE”. Once the user has entered the field using the arrow keys, it will
then display only the operational mode choices available.

modes support the Port Redirect Function. Refer to
Section 5.7.7 for instructions on configuring the operational
modes of all the modules installed in the chassis.

The Port Redirect Function screen, Figure 5-14, allows the user to set
each one of the modules in the chassis (1 through 5), and the ports of the
corresponding module, as a source or destination port. A port can be set to
have one or more destination ports and chassis module slot numbers. For
example, port 1 in module (slot) 1 can be set as a source port with three
destinations, ports 2, 3, and 4 in module (slot) 3. Traffic from port 1 in
module 1 is then automatically redirected to ports 2, 3, and 4 in module 3.
Port 1 in module 1 can also serve as a destination port for other ports and
modules. The port redirect function is extremely useful for
troubleshooting purposes, as it allows traffic to be sent to a particular
port(s) where, with the use of an analyzer or RMON probe, all current
traffic from the source port(s) can be examined.
NOTE

The module number corresponds to the slot number in which
the module resides in the 6C105 chassis (1 through 5).

NOTE

Although traffic from the source port (including, if desired,
errored frames) is sent to the destination port, normal switching
is still performed for all frames on the source port.

Management Mode (Toggle)

This field toggles between DISTRIBUTED and STAND ALONE.
In DISTRIBUTED mode, Local Management is entered via the 6C105
password screen, and all chassis configuration screens are available to the
user. All other modules installed in the chassis that are set for distributed
management may also be accessed via a connection to a single COM port
on one of the modules. The user can then manage all modules within the
chassis and the chassis itself.
NOTE

If the user is establishing a remote connection, such as a Telnet
or SNMP connection, using the IP address of the module, the
chassis LM screens will not be available. To access the chassis
LM screens, the IP address of the chassis must be used to
establish the connection.

In STAND ALONE mode, the module is isolated from the chassis
configuration screens, and the module may not be accessed from a

NOTE

PORT REDIRECT FUNCTION SCREEN
The Port Redirect Function screen may not be available
depending on the operational mode that has been set for the
module. Refer to the Release Notes to see what operational
modes support the Port Redirect Function. Refer to
Section 5.15.9 for instructions on configuring the operational
mode of the module.

The Port Redirect Function screen, Figure 5-29 allows the user to set each
one of the ports on the 6H12X-08 as a source or destination port. A port
can be set to have one or more destination ports. For example, port 1 can
be set as a source port with three destinations, ports 2, 3, and 4. Traffic
from port 1 is then automatically redirected to ports 2, 3, and 4. Port 1 can
also serve as a destination port for other ports. The port redirect function
is extremely useful for troubleshooting purposes, as it allows traffic to be
sent to a particular port(s) where, with the use of an analyzer or RMON
probe, all current traffic from the source port(s) can be examined.
NOTE

Although all traffic from the source port (including, if desired,
errored frames) is sent to the destination port, normal switching
is still performed for all frames on the source port.

To access the Port Redirect Function screen from the Module Specific
Configuration screen, use the arrow keys to highlight the PORT
REDIRECT FUNCTION menu item and press ENTER. The Port

interface. This field will display “Valid” or “Invalid”.
Drop Events (Read-only)

This field displays the total number of times that the RMON agent was
forced to discard frames due to the lack of available switch resources.

NOTE

The Drop Events field does not display the number of frames
dropped, it only displays the number of times that the RMON
agent was forced to discard frames.

Collisions (Read-only)

This field displays the total number of collisions that have occurred on
this interface.
Broadcast Pkts (Read-only)

The Broadcast Pkts field displays the total number of good frames that
were directed to the broadcast address. The value of this field does not
include multicast frames.

B.1.1

Auto-Negotiation

When using the optional FE-100TX Fast Ethernet Interface Modules,
these twisted pair ports have the ability to auto-negotiate the type of
connection required to provide a link to another device. During
Auto-Negotiation, two devices automatically exchange information
“telling” each other what their operating capabilities are. The
Auto-Negotiation feature targets the maximum capabilities that can be
reached between the two devices. For example, the Interface Module port
adjusts to 100 Mbps when the device on the other end of the connection
can also adjust between 10 Mbps or 100 Mbps. If the device on the other
end of the connection can only operate at 10 Mbps, then the port simply
adjusts to 10 Mbps operation.
When Auto-Negotiation is supported at both ends of a link, the two
devices dynamically adjust to full or half duplex operation based on the
maximum capability that can be reached between the two devices. If the
device connected to the 6H12X-08 cannot auto-negotiate, the 6H12X-08
interface operates according to the capabilities of the other device.

OPTIONAL INSTALLATIONS AND
MODE SWITCH BANK SETTINGS

!

Only qualified service personnel should attempt the following
procedures.

CAUTION

This appendix covers the following items:
•

Required tools (Section C.1)

•

Locations, functions, and settings for the mode switches (Section C.2)

•

Installing optional Fast Ethernet Interface Modules (Section C.3)

C.1

REQUIRED TOOLS

You need the following tools to perform the procedures in this appendix:
•

An antistatic wrist strap (provided with 6C105 chassis).

•

A Phillips screwdriver is required when installing optional Fast
Ethernet Interface Modules for ports 7 and 8 into the 6H12X-08.

C.2

SETTING THE MODE SWITCH

These switches are set at the factory and do not need to be changed unless
you intend to perform the following:
•

Force download a new image file from a BootP server.

•

Clear NVRAM and restore all user-entered parameters such as the IP
address and subnet masks to the 6H12X-08 “default” configuration
settings.

•

Clear user-entered passwords stored in NVRAM and restore the
default passwords.

Figure C-1

6H12X-08 Mode Switch Location/Component Layout

Switch definitions and positions are as follows:
•

Switches 1 through 4 – For Cabletron Systems use only.

•

Switch 5 – COM Port Autobaud. The default (OFF) position enables
Autobaud sensing on the COM port for Local Management sessions.
Changing the switch to the ON position disables Autobaud sensing and
sets the COM port to 9600 baud for Local Management sessions.

•

Switch 6 – Forced BootP. Changing the position of this switch (i.e.,
moving the switch from one position to the other) clears download
information from NVRAM and forces the 6H12X-08 to download a
new image file from a BootP server after power to the chassis is
restored.
After changing the position of switch 6 and restarting the module, the
6H12X-08 requests a new image download until it either receives a
new image or the RESET button on the front panel is pressed. When
the RESET button is pressed, the 6H12X-08 continues trying to
contact a BootP server, but will time out in approximately one minute.
If the module times out, the image is downloaded from its FLASH
memory.

Setting the Mode Switch

NOTE

After changing the position of switch 6, DO NOT reapply power
to the chassis until there is a station acting as a BootP server,
which contains the image file.

•

Switch 7 – Clear NVRAM. Changing the position of this switch resets
NVRAM on either the next power up or the next operation of the front
panel RESET switch. ALL user entered parameters, such as IP
addresses, subnet masks, SNMP traps, and switching functions are
restored to their factory default settings.

•

Switch 8 – Reset Password/Community Strings. Changing the position
of this switch clears only the user-entered passwords stored in
NVRAM, and restores the default passwords. Once the 6H12X-08
resets, the passwords can either be reentered or the default passwords
(Public and ENTER) may be used.

NOTE

Do not change the position of switch 8 unless it is necessary to
reset the module super-user configured passwords to their
factory default settings.

Installing Optional Fast Ethernet Interface Modules

To install a Fast Ethernet Interface Module in port slot 7 or 8 of the
6H12X-08, proceed as follows:

!

CAUTION

!

CAUTION

The Fast Ethernet Interface Module and the 6H12X-08 are
sensitive to static discharges. Use an antistatic wrist strap and
observe all static precautions during this procedure. Failure to
do so could damage the module or the 6H12X-08.
The FE-100F3 uses Class 1 lasers. Do not use optical
instruments to view the laser output. The use of optical
instruments to view laser output increases eye hazard. When
viewing the output optical port, power must be removed from
the network adapter.

1. Remove the coverplate from the port slot where the Fast Ethernet
Interface Module will be installed.

TIP

When installing Fast Ethernet Interface Modules in both port
slots 7 and 8, remove the coverplates from both slot openings.
In the following instructions, the optional module is shown
being installed in port slot 8.

To remove a coverplate, refer to Figure C-3 and proceed as follows:
a. Remove the two screws fastening the coverplate to the standoffs.
Save the screws.
b. Lift and remove the coverplate from the top of the front standoffs.
