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
3
2
0.8 W cm or 8 x 10 W m sr-1.
Do not use optical instruments to view the laser output. The use of optical instruments to view

The 2E43-51 also has two slots (5 and 6) for optional 10/100 Fast
Ethernet Interface Modules, and another slot for an optional High Speed
Interface Module (HSIM).
The device can switch each Ethernet network (ENET 1 through ENET 4)
to one another, to the optional interface modules in slots 5 and 6, and to
the HSIM slot. The optional Fast Ethernet Interface Modules provide
uplinks to 100BASE-TX or 100BASE-FX Fast Ethernet networks. The
HSIMs provide additional connectivity to various networking
technologies such as Asynchronous Transfer Mode (ATM), Fiber
Distributed Data Interface (FDDI), and Wide Area Network (WAN).
The 2E43-51 may be used as a tabletop unit or can be installed in a
standard 19-inch rack using the supplied rack mounting hardware.
The 2E43-51 device has one universal ac power supply with automatic
voltage sensing that allows operation using 100–125 or 200–240 Vac,
50/60 Hz.

Chapter 1: Introduction
The 2E43-51R has two power supplies. The power supplies load share
50% (+/-5%) of the power required by the device. If one power supply
fails, the remaining power supply assumes the entire load of the device
without interruption to network traffic. Each power supply module
supports its own ac input connection, which allows the user to connect
each power supply to a different ac power circuit.
1.3.1
Connectivity
The 2E43-51 connects to Ethernet networks or workstations through four
50-pin RJ21 connectors. Each connector serves as a 12-port Ethernet
10 Mbps MicroLAN.
Both of the devices have two front panel slots (ports 5 and 6) for optional
Fast Ethernet Interface Modules to support an uplink to 100 Mbps Fast
Ethernet backbones or a high speed connection to a local server. There is
also space for an optional HSIM to provide additional connectivity to
various networking technologies.
1.3.2
Full Duplex Switched Ethernet
The optional Fast Ethernet Interface Modules for the 2E43-51 can be
configured to operate in Full Duplex Switched Ethernet mode, which
provides 200 Mbps of bandwidth.
1.3.3
Auto-Negotiation
The repeater ports and Fast Ethernet Interface Modules can 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, an FE-100TX Fast
Ethernet Interface Module in a 2E43-51 can adjust to 100 Mbps when the
device on the other end of the connection can also adjust to 100 Mbps. If
the device on the other end of the connection can only operate at
10 Mbps, then the FE-100TX simply adjusts to 10 Mbps operation.
1-4

2E43-51 Overview
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 FE-100TX cannot auto-negotiate, the FE-100TX
Fast Ethernet Interface Module operates according to the capabilities of
the other device.
1.3.4
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.
1.3.5
Runtime IP Address Discovery
This feature enables the 2E43-51 to automatically accept an IP address
from a Boot Strap Protocol (BootP) server on the network into NVRAM
without requiring a user to enter an IP address through Local
Management.
When the 2E43-51 is connected to the network and powered up, Runtime
IP Address Discovery (RAD) checks the 2E43-51 for an IP address. If one
has not yet been assigned (2E43-51 IP address set to 0.0.0.0), RAD
checks to see if any of the 2E43-51 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 server on the network.
2E43-51/2E43-51R User’s Guide
1-5
Download from Www.Somanuals.com. All Manuals Search And Download.
Chapter 1: Introduction
The RAD requests start out at an interval of 1 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 BootP server, or
an IP address is entered using Local Management.
1.3.6
Management
Management of the 2E43-51 is accomplished using SNMP compliant
management tools for in-band Local Management. Out-of-band Local
Management is provided through the RJ45 COM port on the front panel
using a VT100 terminal or a VT100 terminal emulator. In-band remote
management is possible through any SNMP compliant Network
Management Software.
Local Management provides the ability to manage the 2E43-51 and any of
the optional Fast Ethernet Interface Modules installed in ports 5 and 6,
and the optional High Speed Interface Module (HSIM).
The associated HSIM user’s guide provides detailed information about
the HSIM Local Management.
1.3.7
Switching Options
The 2E43-51 provides 802.1D switching, 802.1Q switching or SecureFast
Switching Virtual Network Services between all of the front panel
interfaces including Fast Ethernet Interface Modules and High Speed
Interface Module (HSIM).
IEEE 802.1Q switching and SecureFast switching allow for future
migration to Virtual Network technologies without requiring the
replacement of existing equipment.
1.3.8
Standards Compatibility
The 2E43-51 provides IEEE 802.1D Spanning Tree Algorithm (STA)
support to enhance the overall reliability of the network and protect
against “loop” conditions. The 2E43-51 also supports 100BASE-TX and
100BASE-FX Fast Ethernet standards and 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.

Connecting a Fiber Optic Segment to the
FE-100FX and FE-100F3
The FE-100FX and FE-100F3 have SC style network ports. See
Figure 3-11. Cabletron Systems offers optional fiber optic cables that use
SC style connectors. The ST connectors are keyed to ensure proper
crossover of the transmit and receive fibers.
An odd number of crossovers (preferably one) must be
maintained between devices so that the transmit port of one
NOTES
device is connected to the receive port of the other device and
vice versa.
If the fiber optic cable being used has SC style connectors that
do not resemble MIC style connectors, or has SC connectors
on one end and a different type on the other, such as ST
connectors, ensure that the proper crossing over occurs.
Fiber Optic Network Connection
1. Remove the protective plastic covers from the fiber optic ports on the
applicable port on the module and from the ends of the connectors.
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.
!
CAUTION
Do not touch the ends of the fiber optic strands, and do not let
the ends come in contact with dust, dirt, or other contaminants.
Contamination of the ends causes problems in data
transmissions. If the ends become contaminated, blow the
surfaces with a canned duster. A fiber port cleaning swap
saturated with optical-grade isopropyl alcohol may also be used
to clean the fiber optic ends.
!
CAUTION
2. Insert one end of the SC connector into the FE-100FX or FE-100F3
installed in the 2E43-51. See Figure 3-11.

Displays the subnet mask for the 2E43-51. 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. For details about how to change the subnet mask from its default
value, refer to Section 5.7.2.
Default Gateway (Modifiable)

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 Local Management
Password screen. To enter a new lockout time, refer to Section 5.7.8.
Device Uptime (Read-Only)
Displays the total time that the device has been operating.
Operational Mode (Selectable)
Allows the user to set the 2E43-51 so it operates as a an 802.1D switch
(802.1D SWITCHING), an IEEE 802.1Q switch (802.1Q SWITCHING),
or a Cabletron Systems SecureFast switch (SECURE FAST VLAN).
In 802.1D SWITCHING mode, the 12 connections on each RJ21 port
(ENET1 – ENET4) act as repeaters, and may be switched to each other
and to any Fast Ethernet Interface Module and HSIM port(s) in the

The following describes each field of the Switch Configuration screen:
Switch Address (Read-Only)
Displays the MAC address of the switch.
Number of Ports (Read-Only)
Displays the total number of switched ports on the 2E43-51.
Ethernet networks 1 through 4 (ENET 1 through ENET 4) are
considered as single switched ports.
NOTE
Type of STA (Toggle)
Allows the user to set the method that switches use to decide which
switch is the controlling (Root) switch when two or more switches exist in
parallel (Spanning Tree Algorithm). Valid selection is IEEE, DEC, and
None. To set the STA, refer to Section 5.10.1.
Age Time (Modifiable)
Allows the user to set the amount of time (in seconds) that the 2E43-51
keeps an address in its switch table before discarding it. An address is
automatically discarded when a valid Bridge Protocol Data Unit (BPDU)
is not received from that address within the time specified in the Age Time
field. To change the Age Time field from the default value of 300 seconds,
refer to Section 5.10.2.
Port # (Read-Only)

Chapter 5: Local Management
In normal operation, the port with an FE-100TX installed
NOTE
automatically establishes 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.
If an FE-100TX is installed, the field steps to Auto-Negotiation,
10Base-T, 10Base-TFD (full duplex), 100Base-TX, and 100Base-TXFD
(full duplex). In normal operation, the port with an FE-100TX installed is
capable of auto-negotiating the operational mode and no further user
setup is required. Section 5.14.2 describes how to manually configure an
FE-100TX.
In Auto Negotiation, the FE-100TX negotiates to the highest common
denominator of the two interfaces. The order of priority of negotiation is
100Base-TXFD, 100Base-TX, 10Base-TFD, and 10Base-T.
Advertised Ability (Selectable)
During auto-negotiation, the FE-100TX “tells” the device at the other end
of the segment about its capabilities. The capabilities of a port (5 or 6)
with an FE-100TX installed are 10Base-T, 10Base-TFD (full duplex
mode), 100Base-TX and 100Base-TXFD (full duplex mode). In normal
operation, with all capabilities enabled, the FE-100TX “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 might be enabled so that only devices that operate at
how to enable or disable advertised modes.
5.14.1 Configuring an FE-100FX or FE-100F3
When an FE-100FX or FE-100F3 is installed in port 5 or 6, it must be
manually set to operate in the same technology as the device at the other
end of the connected segment. Section 5.14.1.1 provides instructions for
manually configuring the port with an FE-100FX or FE-100F3 interface.

5.16 PORT REDIRECT FUNCTION SCREEN
The Port Redirect Function screen can only be used if the
operational mode of the device has been set to 802.1D
NOTE
SWITCHING. Refer to Section 5.7.9, Setting the Operational
Mode, for instructions on configuring the device to operate in
this mode.
The Port Redirect Function screen, Figure 5-23, allows the user to set
each network port (ENET 1 through 4, port 5, and port 6) as a source or
destination port. (ENETs 1 through 4 are shown as 1 through 4 on the
screen.) 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.

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. Do NOT attempt a Forced BootP unless a
BootP server has been configured for the 2E43-51. The BootP server
references the location of a station acting as a Trivial File Transfer
Protocol (TFTP) server containing the 2E43-51 image file. When the
position of Switch 6 is changed and the power is cycled to the
2E43-51, the device requests the image file location from the BootP
server and uses TFTP to download the image from the TFTP server. If
one of these requirements is not met, the 2E43-51 will continue to
request either the BootP server or the TFTP server until the RESET
button on the 2E43-51 is pressed. Once the RESET button is pressed,
the 2E43-51 will reset after one minute and load the image stored in
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
the IP address, device names, etc., are reset to the factory default
settings. Once the 2E43-51 resets, you can either use the factory
default settings or reenter your own parameters.
•
Switch 8 – Reset Password/Community Strings. Changing the
position of this switch clears user-entered passwords stored in
NVRAM, and restores the factory default passwords on the next
power-up. Once the 2E43-51 resets, you can either use the factory
default settings or reenter your own passwords.
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.

NOTE
To install a Fast Ethernet Interface Module in port slot 5 or 6, proceed as
follows:
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.
!
CAUTION
The Fast Ethernet Interface Module and the 2E43-51 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 2E43-51.
