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

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.

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.

Accessing Local Management  
The User’s password is one of the community names specified  
in the SNMP Community Names screen. Access to certain  
Local Management capabilities depends on the degree of  
access accorded that community name. Refer to Section 5.8.  
NOTE  
If an invalid password is entered, the terminal beeps and the  
cursor returns to the beginning of the password entry field.  
Entering a valid password causes the associated access level  
to display at the bottom of the screen and the Device Menu  
screen to appear.  
If no activity occurs for several minutes, the Local Management  
Password screen redisplays and the password has to be  
reentered.  
5.4.1  
Navigating Local Management Screens  
The 2E4X-27 Local Management application consists of a series of menu  
screens. Navigate through Local Management by selecting items from the  
menu screens.  
The 2E43-51 supports three modes of switch operation. The switching  
modes are as follows:  
802.1Q Switching (port based VLAN switching)  
SecureFast VLAN (Cabletron Systems SecureFast switching)  
Depending on the Operational Mode set for the device, the hierarchy of  
the Local Management screens differs as shown in Figure 5-4, Figure 5-5  
and Figure 5-6. Refer to the appropriate figure that relates to the  
Operational Mode set for the device to see the applicable Local  
Management screen hierarchy.

No Link – There is no link signal present and no valid physical  
connection to another device.  
Current Oper. Mode (Read-only)  
This field displays the current operating mode of ports 5 and 6.  
Depending on whether a 100BASE-FX or 100BASE-TX Fast Ethernet  
Interface Module is installed, this field displays the following:  
With a 100BASE-FX interface: 100Base-FX, 100Base-FXFD (full  
duplex), or N/A when the port slot is empty.  
With a 100BASE-TX interface: Unknown, 10Base-T, 10Base-TFD  
(full duplex), 100Base-TX, 100Base-TXFD (full duplex) or N/A when  
the port slot is empty.  
Desired Oper. Mode (Selectable)  
This field allows the user to select the desired operational mode for an  
interface in port 5 or 6. The field toggles between 100Base-FX and  
100Base-FXFD (full duplex) when an FE-100FX or FE-100F3 is  
installed. Section 5.14.1 describes how to configure a port with an  
FE-100FX or FE-100F3.

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  
100 Mbps can communicate with that port. Section 5.14.2.2 describes  
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.

State (Selectable)  
Used to select the state of security for frames received by any port on the  
connector. The states are as follows:  
Secure – Allows the ports on the connector to receive only those  
frames with the address as determined by the selection in the  
Lock/Learn field.  
NonSecure – Allows the ports on the connector to receive all frames.  
The source address of received frames is not examined and the frames  
are processed in a non secure state.  
Lock/Learn (Selectable)  
Used to select the type of security for frames received by any port on the  
connector. The security types are as follows:  
LockOnNext – The next frame received by each port is examined to  
learn its source address. As the source address of a frame is learned on  
a port, only those frames received with that same source address are  
processed on that port. Any other address detected is considered as an  
intruder and the device executes the actions selected in the Action On  
Intruder field.

This field displays the source of the statistics data that is currently being  
displayed on the screen. Figure 5-31 shows that the data source for this  
RMON index is Interface 1 (ENET 1) by displaying the name IfIndex.1.  
If the screen was displaying RMON statistics for Interface 4 (ENET 4),  
the name displayed would be IfIndex.4.  
Owner (Read-only)  
This field displays the name of the entity that configured this entry.  
Status (Read-only)  
The Status field displays the current operating status of the displayed  
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 packets due to the lack of available switch resources.  
The Drop Events field does not display the number of packets  
dropped, it only displays the number of times that the RMON  
NOTE  
agent was forced to discard packets.  
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 packets that  
were directed to the broadcast address. The value of this field does not  
include multicast packets.

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.

The installation instructions for the High Speed Interface  
Modules are in the associated user’s guide.  
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.  
!
CAUTION  
When installing Fast Ethernet Interface Modules in both port  
slots 5 and 6, remove the coverplates from both slot openings.  
In the following instructions, the optional module is shown  
being installed in port slot 6.  
TIP  
1. Remove the coverplate from the port slot where the Fast Ethernet  
Interface Module will be installed. Refer to Figure C-4 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.
