SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
THE FE-100F3 FAST ETHERNET INTERFACE MODULE, FPIM-05 AND
FPIM-07 FDDI PORT INTERFACE MODULES, AND APIM-29 ATM
PORT INTERFACE MODULE USE 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.

OVERVIEW

The 6H122-16 (Figure 1-1) is a Fast Ethernet interface module for the
Cabletron Systems 6C105 chassis. The module provides sixteen RJ45
switched ports for unshielded twisted pair (UTP) cabling connectivity.
The 6H122-16 is used to connect individual high-bandwidth user devices,
such as workstations, and provide a central switching point for multiple
10/100 Mbps Fast Ethernet segments.

1.3.1

Connectivity

The 6H122-16 connects to Ethernet/Fast Ethernet networks or
workstations through sixteen RJ45 ports on the front panel. These ports
are IEEE 802.3u 100BASE-TX compliant, and use Category 5 unshielded
twisted pair cables of lengths up to 100 meters with impedances between
85 and 111 ohms.

1.3.2

Management

Management of the 6H122-16 module and 6C105 chassis and any
optional equipment is accomplished using Local Management tools or
remote SNMP management stations. Local Management is accessible
through the front panel RS232 COM port using a local VT100 terminal,
or a remote VT100 terminal via a modem connection. Local Management
is also accessible in-band via a Telnet connection. In-band remote
management is possible through any SNMP compliant Network
Management Software.

1.3.3

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 6H122-16, can be used to manage the entire
chassis, and any other attached module through Local Management,
SNMP, or Telnet applications.

1.3.4

Switching Options

The 6H122-16 provides 802.1D switching, 802.1Q switching, or
SecureFast Switching Virtual Network Services between all of the front
panel interfaces.
SecureFast switching and 802.1Q switching allow for future migration to
Virtual Network technologies without requiring the replacement of
existing equipment.

1.3.5

Full Duplex Switched Ethernet

Ports 1 through 14 support Full Duplex Switched Ethernet (FDSE)
operation if the port is operating in Standard Ethernet mode (10 Mbps).
This provides up to 20 Mbps of bandwidth. Ports 15 and 16 also support
Full Duplex operation in Fast Ethernet mode (100 Mbps). This provides
up to 200 Mbps of bandwidth.

1.3.6

Remote Monitoring

The 6H122-16 supports all Ethernet Remote Monitoring (RMON)
groups, which include Statistics, Alarms, Events and History. These four
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.
An example of an Action would be to turn off a MIB-2 interface if a
broadcast threshold is crossed.

1.3.7

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.

1.3.8

Runtime IP Address Discovery

This feature enables the modules 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 modules are connected to the network and powered up,
Runtime IP Address Discovery (RAD) checks the modules for an IP
address. If one has not yet been assigned (module and 6C105 chassis IP
address set to 0.0.0.0), RAD checks to see if any of the module interfaces
have a link. If so, RAD sends out Reverse Address Resolution Protocol
(RARP) and BootP requests to obtain an IP address from a RARP or
BootP server on the network.
The RAD requests start out at an interval of one second. The interval then
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 RARP or BootP
server, or an IP address is entered using Local Management.

1.3.9

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).

1.3.10 Auto-Negotiation
Twisted pair ports on the 6H122-16 module 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 6H122-16 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 6H122-16 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 6H122-16 cannot auto-negotiate, the 6H122-16
interface operates according to the capabilities of the other device.

NOTE

All ports support standard Ethernet, standard full duplex
operation, and Fast Ethernet. Ports 1 through 14 do not
support Fast Ethernet in full duplex operation. However, ports

Telnet Connections

Once the module or chassis has a valid IP address, the user can establish a
Telnet session with Local Management from any TCP/IP based node on
the network. Telnet connections to the 6H122-16 require the community
name passwords assigned at the SNMP Community Names screen of
either the 6C105 chassis, or the module. For additional information about
community names, refer to Section 5.8. Refer to the instructions included
with the Telnet application for information about establishing a Telnet
session.

5.3.4

Connecting an Uninterruptible Power Supply

If the 6C105 chassis is connected to an American Power Conversion
(APC) Uninterruptible Power Supply (UPS) for protection from a loss of
power, a connection from the COM port of a module to the UPS can be
made to monitor the status of the UPS. To use the COM port for this
purpose, it must be reconfigured to support the UPS application. This
procedure is performed from the General Configuration screen of the
interface module. Section 5.15.11, Configuring the COM Port, provides
detailed instructions on configuring the COM port for UPS applications.
Refer to the UPS documentation for details on how to access the status
information.
Use the Console Cable Kit provided with the 6C105 chassis to attach the
UPS to the module COM port as shown in Figure 5-2.
Connect the UPS device to the COM port of the 6H122-16 as follows:
1. Connect the RJ45 connector at one end of the cable to the COM port
on the 6H122-16.
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 (refer to the particular UPS device’s user
instructions for more specific information about the monitoring
connection).

ACCESSING LOCAL MANAGEMENT

Access to Local Management is controlled through the Password screen,
Figure 5-3. Whenever a connection is made to the 6H122-16 the
Password screen displays. Before continuing, the user must enter a
password which is compared to the previously stored passwords. The
level of access allowed the user depends on the password. To set or
change passwords refer to Section 5.8. The following steps describe the
procedure to access Local Management.
1. Turn on the terminal. Press ENTER (this may take up to four times,
because the COM port of the 6H122-16 auto-senses the baud rate of
the terminal) until the 6C105 Local Management Password screen,

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.
5-16

6H122-16 User’s Guide

Chassis Configuration Screen
Subnet Mask (Modifiable)

NOTE

When a valid IP address is assigned, the Subnet Mask field
automatically enters the default mask that corresponds with
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 your 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.
Section 5.7.2 describes how to change the subnet mask from the default
value.
Chassis Date (Modifiable)

Contains a value that the chassis recognizes as the current date. When the
chassis date is modified, 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.
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.

Chapter 5: Local Management
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 16 ports located on the front panel are
bridged to each other.
When the operational mode is set to 802.1Q SWITCHING, the 6H122-16
acts as an IEEE 802.1Q switch. The module can be configured to increase
its switching functionality by creating and maintaining port based Virtual
LANs (VLANs).
For details on how to select the Operational Mode, refer to Section 5.7.7.

5.7.1

NOTE

Operating a chassis without a fan tray installed may cause the

a chassis without a fully functioning fan tray unit.

PORT REDIRECT FUNCTION SCREEN
The Port Redirect Function screen may not be available
depending on the operational mode that has been set for the
chassis. Refer to your Release Notes to see what operational
modes support the Port Redirect Function. Refer to
Section 5.7.7, Setting the Operational Mode, for instructions
on configuring the operational mode 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 installed, 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.
NOTES

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

Ethernet Interface Configuration Screen for the 6H122-16

All ports are capable of 10 or 100 Mbps operation, however
only ports 15 and 16 support Full Duplex Switched Ethernet
(FDSE) for 100 Mbps.
Ports 15 and 16 auto-negotiate to 100BASE-TXFD by default
and can also be manually set to 100BASE-TXFD, but ports 1
through 14 cannot be set to nor auto-negotiate to
100BASE-TXFD.
All ports can be set and auto-negotiate to 10BASE-TXFD.

Ethernet Interface Configuration

The following section briefly explains each field of the Ethernet Interface
Configuration screen:
Port Num (Read-Only)

Displays the number of the front panel interface.
Port Type (Read-Only)

Displays the name of the interface installed in ports 1 through 16. All
ports are identified as FE-100TX.
Link Status (Read-Only)

Indicates whether or not there is a physical connection from a particular
port to another 10BASE-T, 100BASE-TX, or 100BASE-TXFD device.
One of the following values is displayed:
•

Link – There is a link signal present and a valid physical connection to
another 10BASE-T, 100BASE-TX, or 100BASE-TXFD device.

•

No Link – There is no link signal present and there is no valid physical
connection to another device.

Current Oper. Mode (Read-only)

This field displays the current operating mode of a port. Depending on the
connection negotiated, this field displays the following:
100Base-TX interface – Auto-Neg, Unknown (if there is no Link),
10Base-T, 10Base-TFD (full duplex), 100Base-TX, or
100Base-TXFD (full duplex, ports 15 and 16 only).
Desired Oper. Mode (Selectable)

This field allows the user to select the desired operational mode for an
interface.
FE-100TX Interface – The field steps between Auto-Neg, 10Base-T,
10Base-TFD (full duplex), 100Base-TX, and 100Base-TXFD (full
duplex, ports 15 and 16 only). In normal operation, the port with an
FE-100TX interface is capable of auto-negotiating the operational mode
and no further user setup is required. For details on how to set the
Operational Mode, refer to Section 5.19.2.
NOTE

In normal operation, ports 1 through 16 automatically establish
a link with the device at the other end of the segment without
requiring user setup. However, Local Management provides the
user with the option of manually configuring that port.

6H122-16 User’s Guide

5-67

Chapter 5: Local Management
Advertised Ability (Selectable)

During auto-negotiation, the port “tells” the device at the other end of the
segment what its capabilities are. The capabilities of a port are
10BASE-T, 10BASE-TFD (full duplex mode), 100BASE-TX and
100BASE-TXFD (full duplex mode, ports 15 and 16 only). In normal
operation, with all capabilities enabled, the port “advertises” that it has
the ability to operate in any mode. The Network Manager may choose to
set up the port so that only a portion of the available capabilities are
advertised and the others are disabled. For example, only 100BASE-TX
and 100BASE-TXFD (ports 15 and 16 only) might be enabled so that
only devices that operate at 100 Mbps can communicate with that port.
Section 5.19.3 describes how to enable or disable advertised modes.
Flow Control Admin Status (Selectable)

Enabling this setting controls whether or not the switch will block traffic
on all ports when there is excessive traffic for the switch to process. This
will clear the ports and allow the switch to process the current frame
information. Section 5.19.4 explains how to enable or disable this option.

5.19.1 Configuring the Ports
In normal operation, a 6H122-16 interface automatically establishes a
link with the device at the other end of the segment and no user setup is
required. Section 5.19.2 and Section 5.19.3 provide instructions for
manually configuring the interface.

5.19.2 Setting the Operational Mode
Use this field to set the active technology. This field steps between
Auto-Negotiation, 10BASE-T, 10BASE-TFD (full duplex),
100BASE-TX, and 100BASE-TXFD (full duplex, ports 15 and 16 only).
If Auto-Negotiation is selected, the port automatically sets the active
technology. To manually set the active technology through Local
Management, proceed as follows:
1. Use the arrow keys to highlight the Desired Oper. Mode field.
2. Use the SPACE bar to select the desired mode. Press ENTER. If any
mode other than auto-negotiation is selected, the port only operates in
the chosen mode and auto-negotiation is disabled.

3. Use the arrow keys to highlight the SAVE command. Press ENTER.
The message “SAVED OK” displays and Local Management saves
the changes to memory. The selected mode is displayed in both the
Desired Operational Mode field and the Current Operational Mode
field.

5.19.3 Setting the Advertised Ability
During normal operation, ports 1 through 16 auto-negotiate to the highest
speed possible. Under some circumstances, the Network Administrator
may want the port to advertise only some of the available modes and not
operate in other modes. This field steps between 10BASE-T,
10BASE-TFD (full duplex), 100BASE-TX, and 100BASE-TXFD (ports
15 and 16 only).
To set the advertised ability, proceed as follows:
1. Use the arrow keys to highlight the Advertised Ability field.
2. Use the SPACE bar to select the desired mode.
3. Use the RIGHT-ARROW key to move across to the
Enabled/Disabled field to the right of the selection.

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 your 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 5-32, allows the user to set
each one of the ports on the 6H122-16 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.

APPENDIX B
MODE SWITCH BANK SETTINGS
This appendix covers the following items:
•

Required tools (Section B.1)

•

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

B.1

REQUIRED TOOLS

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

Antistatic wrist strap (provided with 6C105 chassis)

B.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 6H122-16 “Default” configuration
settings.

•

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

!

CAUTION

The 6H122-16 is sensitive to static discharges. Use an
antistatic wrist strap and observe all static precautions during
this procedure. Failure to do so could damage the 6H122-16.

Figure B-1

6H122-16 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 6H122-16 to download a
new image file from a BootP server after power to the chassis is
restored.

NOTE

B-2

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.

6H122-16 User’s Guide

Setting the Mode Switch

•

After changing the position of switch 6 and restarting the module, the
6H122-16 requests a new image download until they either receive a
new image or the RESET button on the front panel is pressed. When
the RESET button is pressed, the 6H122-16 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.

•

Switch 7 – Clear NVRAM. Changing the position of this switch resets
NVRAM on the next power up. 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 6H122-16
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.
