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  
-6  
radiant power exiting the fiber (under normal conditions) is -12.6 dBm or 55 x 10 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  
-2

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.

Chapter 1: Introduction  
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.

Overview  
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.

Chapter 1: Introduction  
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.  
All ports support standard Ethernet, standard full duplex  
operation, and Fast Ethernet. Ports 1 through 14 do not  
NOTE  
support Fast Ethernet in full duplex operation. However, ports  
15 and 16 do support full duplex Fast Ethernet.  
1.3.11 Broadcast Suppression  
Broadcast Suppression allows a limit to be set on the number of receive  
broadcast frames per port/per second to be forwarded out the other ports  
on the module. Any broadcast frames above the specified limit are  
dropped. In the event that broadcast frames are being suppressed,  
multicast and unicast frames continue to be switched.

Overview  
1.3.12 Standards Compatibility  
The 6H122-16 is fully compliant with the IEEE 802.3u standard. The  
6H122-16 provides IEEE 802.1D Spanning Tree Algorithm (STA)  
support to enhance the overall reliability of the network and protect  
against “loop” conditions. The 6H122-16 supports a wide variety of  
industry standard MIBs including RFC 1213 (MIB II), RFC 1757  
(RMON), 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.  
1.3.13 LANVIEW Diagnostic LEDs  
LANVIEW diagnostic LEDs serve as an important troubleshooting aid by  
providing an easy way to observe the status of individual ports and overall  
network operations. Chapter 4 provides details about the 6H122-16  
LANVIEW LEDs.  
1.3.14 Year 2000 Compliant  
The 6H122-16 module and 6C105 chassis have an internal clock that can  
maintain the time and date beyond the year 1999.

OVERVIEW  
Local Management for the 6H122-16 consists of a series of management  
screens that allows management of the module, the attached segments,  
and the 6C105 chassis. The management screens allow the following  
tasks to be performed:  
Manage any interface module in the chassis via a connection to a  
single interface module.  
Assign IP addresses and subnet masks to the 6H122-16 module, and  
the 6C105 chassis.  
Control access to the 6H122-16 module and the 6C105 chassis by  
establishing community names.  
Download a new image of operating software.  
Designate which Network Management workstations receive SNMP  
traps from the 6H122-16 module and the 6C105 chassis.  
Monitor the environmental status of the 6C105 chassis.  
View switch, interface, and RMON statistics.  
Assign ports to operate in standard or full duplex mode.  
Enable trunking of ports to perform load sharing.  
There are three ways to access Local Management:  
Locally using a VT type terminal connected to the COM port of the  
6H122-16.  
Remotely using a VT type terminal connected through a modem.  
In-band through a Telnet connection.

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  
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,

Navigating Local Management Screens  
The 6H122-16 Local Management application consists of a series of  
menu screens. Navigate through Local Management by selecting items  
from the menu screens.  
The 6H122-16 supports three modes of switch operation. The switching  
modes are as follows:  
802.1D SWITCHING (IEEE 802.1D switching)  
802.1Q SWITCHING (802.1Q port based VLANs)  
SECURE FAST VLAN (Cabletron Systems SecureFast Switching)  
which screens are supported in each of the three available  
switching modes.  
NOTE  
The switch operational mode may be set in either the Chassis  
Configuration screen (Section 5.7), or the General Configuration screen  
of the module (Section 5.15). Depending on the Operational Mode set for  
the module, the hierarchy of Local Management screens differs as shown

Chassis Configuration Screen  
Subnet Mask (Modifiable)  
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.  
NOTE  
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)  
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.

automatically enters the default mask that corresponds with  
NOTE  
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.  
To change the subnet mask from its default, perform the following steps:  
1. Use the arrow keys to highlight the Subnet Mask field.  
2. Enter the subnet mask into this field using Decimal Dotted Notation  
(DDN) format.  
For example: 255.255.255.0  
3. Press ENTER. If the subnet mask is valid, the cursor returns to the  
beginning of the Subnet Mask field. If the entry is not valid, the Event  
Message Line displays “INVALID SUBNET MASK OR FORMAT  
ENTERED”. Local Management does not alter the current value, but  
it does refresh the Subnet Mask field with the previous value.  
4. Use the arrow keys to highlight the SAVE command, then press  
ENTER. The changes are saved to memory.

SNMP COMMUNITY NAMES SCREEN  
The SNMP Community Names menu item allows the user to set Local  
Management community names. Community names act as passwords to  
Local/Remote Management and provide security access to the 6C105.  
Access to the 6C105 is controlled by enacting any of three different levels  
of security authorization (read-only, read-write, and super-user).  
Super-User access gives the user full management privileges,  
allows existing passwords to be changed, and all modifiable

SNMP Community Names Screen  
The following explains each SNMP Community Names screen field:  
Community Name (Modifiable)  
Displays the user-defined name through which a user accesses 6C105  
management. Any community name assigned here acts as a password to  
Local/Remote Management.  
Access Policy (Read-Only)  
Indicates the access accorded each community name. Possible selections  
are as follows:  
read-only  
read-write  
super-user  
This community name allows read-only access  
to the 6C105 MIB objects, and excludes access  
to security-protected fields of read-write or  
super-user authorization.  
This community name allows read and write  
access to the 6C105 MIB objects, excluding  
security protected fields for super-user access  
only.  
This community name permits read-write  
access to the 6C105 MIB objects and allows the  
user to change all modifiable parameters  
including community names, IP addresses,  
traps, and SNMP objects.  
5.8.1  
Establishing Community Names  
The password used to access Local Management at the Password screen  
must have Super-User access in order to view and edit the SNMP  
Community Names screen. Using a password with read-only or  
read-write access does not allow the user to view or edit the SNMP  
Community Names screen.  
Any community name assigned in the SNMP Community  
Names screen is a password to its corresponding level of  
NOTE  
access to Local Management. The community name assigned  
Super-User access is the only one that gives the user complete  
access to Local Management.

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

Operational Mode (Selectable)  
This field sets the 6H122-16 to operate as an IEEE 802.1D switch  
(802.1D SWITCHING option), an IEEE 802.1Q switch (802.1Q  
SWITCHING option), or as a Cabletron Systems SecureFast switch  
(SECURE FAST VLAN option).  
In 802.1D SWITCHING mode, the 16 ports located on the front panel are  
bridged to each other.  
In 802.1Q SWITCHING mode, the 6H122-16 is able to increase its  
switching functionality by creating and maintaining IEEE port based  
VLANs.  
When the operational mode is set to SECURE FAST VLAN, the  
6H122-16 acts as a SecureFast switch. With the Cabletron Systems  
VLAN Manager software, the module is able to increase its switching  
functionality by creating and maintaining Virtual LANs (VLANs).  
For details on how to select the Operational Mode, refer to Section 5.15.9.  
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.

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.

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  
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  
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  
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.

This field steps through TFTP, RUNTIME and BOOTP. If set for BOOTP,  
the module sends out a BootP request to determine the IP address of the  
TFTP server and the filename of the image to be downloaded. If set for  
TFTP or RUNTIME, the 6H122-16 attempts a TFTP download based on  
the IP address and filename entered in the fields at the bottom of the Flash  
Download screen. Section 5.22.1 describes how to download using TFTP.

Port Redirect Function Screen  
5.23 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.  
NOTE  
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.  
Although all traffic from the source port (including, if desired,  
errored frames) is sent to the destination port, normal switching  
NOTE  
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  
Redirect Function screen displays.

Data Source (Read-only)  
This field displays the source of the statistics data that is currently being  
displayed on the screen. Figure 5-37 shows that the data source for this  
RMON index is Interface XX by displaying the name IfIndex.XX. If the  
screen was displaying RMON statistics for Interface 1 (port 1), the name  
displayed would be IfIndex.1.  
Owner (Read-only)

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.  
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 disablesAutobaud 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.  
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.

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.  
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.
