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.

2H23-50R/2H33-37R User’s Guide
Overview
The 2H23-50R is a high speed network repeater/switch device that
provides four Ethernet networks and four Fast Ethernet networks (RJ21
MicroLANs, CONN 1 through CONN 4) and two slots (5 and 6) for
optional Fast Ethernet Interface Modules. The RJ21 connectors each
consist of 12 repeater ports that are able to reside on the Ethernet
(10 Mbps) or the Fast Ethernet (100 Mbps) network. Each Ethernet and
Fast Ethernet network supports 802.1D switching (bridging), Cabletron
Systems SecureFast Switching Virtual Network technology and IEEE
802.1Q Port Based Virtual Local Area Networks (VLANs). Slots 5 and 6
support Fast Ethernet Interface Modules to provide uplinks to
100BASE-TX or 100BASE-FX Fast Ethernet Networks.
The 2H33-37R is a high speed network repeater/switch device that
provides three Ethernet networks and three Fast Ethernet networks (RJ21
MicroLANs, CONN 1 through CONN 3) and one slot for an optional
High Speed Interface Module (HSIM). The RJ21 connectors each consist
of 12 repeater ports that are able to reside on the Ethernet (10 Mbps) or
the Fast Ethernet (100 Mbps) network. Each Ethernet and Fast Ethernet
network supports 802.1D switching (bridging), Cabletron Systems
SecureFast Switching Virtual Network technology and IEEE 802.1Q Port
Based Virtual Local Area Networks (VLANs). The 2H33-37R can be
equipped with an optional HSIM to provide additional connectivity to
other high speed networking technologies such as Asynchronous Transfer
Mode (ATM), Fiber Distributed Data Interface (FDDI), and Wide Area
Network (WAN).
The device may be used as a tabletop unit or can be installed in a standard
19-inch rack using the supplied rack mounting hardware.
The 2H23-50R and 2H33-37R have two power supplies with automatic
voltage sensing that allows operation using 100–125 or 200–240 Vac,
50/60 Hz. 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.

Full Duplex Switched Ethernet
The optional Fast Ethernet Interface Modules for the 2H23-50R 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 2H23-50R 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
2H23-50R/2H33-37R User’s Guide
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
SmartTrunking
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 2H23-50R or 2H33-37R (device) to
automatically accept an IP address from a Boot Strap Protocol (BootP) or
Reverse Address Resolution Protocol (RARP) server on the network into
NVRAM without requiring a user to enter an IP address through Local
Management.
When the device is connected to the network and powered up, Runtime IP
Address Discovery (RAD) checks the device for an IP address. If one has
not yet been assigned (2H23-50R IP address set to 0.0.0.0), RAD checks
to see if any of the device’s interfaces have a link. If so, RAD sends out
RARP and BootP requests to obtain an IP address from a server on the
network.
2H23-50R/2H33-37R User’s Guide
1-5
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 server, or an IP
address is entered using Local Management.
1.3.6
Management
Management of the 2H23-50R or 2H33-37R 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 2H23-50R and
2H33-37R and any of the optional Fast Ethernet Interface Modules
installed in slots 5 and 6 of the 2H23-50R, or an optional High Speed
Interface Module (HSIM) in a 2H33-37R.
The associated HSIM user’s guide provides detailed information about
the HSIM Local Management.
1.3.7
Switching Options
The 2H23-50R and 2H33-37R provide 802.1D switching, 802.1Q
switching or SecureFast Switching Virtual Network Services between all
of the front panel interfaces including Fast Ethernet Interface Modules
installed in a 2H23-50R or an HSIM installed in a 2H33-37R.
IEEE 802.1Q switching and SecureFast switching allow for future
migration to Virtual Network technologies without requiring the
replacement of existing equipment.

Connecting a UTP Segment to the FE-100TX
To ensure proper operation, use only Category 5 Unshielded
Twisted Pair (UTP) cabling that has an impedance between 85
and 111 ohms.
An FE-100TX installed in slot 5 and/or 6 of a 2H23-50R has an internal
crossover switch. When connecting a workstation, use a straight-through
cable and set the Fast Ethernet Interface Module crossover switch shown
in Figure 3-7 to the crossed over position marked with X. When
connecting networking devices, such as another bridge, repeater, or
router, use a straight-through cable and set the Fast Ethernet Interface
Module crossover switch shown in Figure 3-7 to the straight-through
position (not crossed over), marked with =.

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 3-10. 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.
NOTES
An odd number of crossovers (preferably one) must be
maintained between devices so that the transmit port of one
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.
!
CAUTION
!
CAUTION
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.
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 clean with a canned duster. A fiber port cleaning swab
saturated with optical-grade isopropyl alcohol may also be used
to clean the fiber optic ends.
2. Insert the SC connector at one end of the fiber optic cable into the
FE-100FX or FE-100F3 installed in the 2H23-50R. See Figure 3-10.

ACCESSING LOCAL MANAGEMENT
Access to Local Management is controlled through the Local
Management Password screen shown in Figure 5-3. Whenever a
connection is made to the 2H23-50R or 2H33-37R the Local
Management Password screen displays. Before continuing, the user must
enter a password (community name) 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 auto-senses the baud rate of the terminal) until
the 2H23-50R or 2H33-37R Local Management Password screen
displays. It is the automatic line speed seeking feature of the port that
makes it necessary at times to press ENTER several times.

SWITCHING), or as a Cabletron Systems SecureFast switch (SECURE
FAST VLAN).
In all three modes of operation, the 12 connections on each RJ21 port
(CONN1 – CONN4 on 2H23-50R or CONN1 – CONN3 on 2H33-37R)
may be assigned individually to operate at 10 Mbps or 100 Mbps. The
connections that share either 10 Mbps or 100 Mbps operation reside on
one network (two networks per RJ21 port).
In the 802.1D SWITCHING mode, each of the networks are
automatically bridged to each other and to any Fast Ethernet Interface
Module in the 2H23-50R or HSIM port(s) in the 2H33-37R.
In the 802.1Q SWITCHING mode, the switching functionality of the
device can be increased by creating and maintaining IEEE 802.1Q port
based Virtual LANs (VLANs).
In the SECURE FAST VLAN mode, the device acts as a SecureFast
switch. With the Cabletron Systems VLAN Manager software, the device
is able to increase its switching functionality by creating and maintaining
VLANs.

Listening: The switch is not adding information to the Transparent
Database. The switch is monitoring the Bridge Protocol Data Unit
(BPDU) traffic while preparing to move from the learning to the
forwarding state.
Learning: The switch is learning the addresses on this interface. The
switch enters the learning state when the Transparent Database is created
(during start-up or after being deleted), or when the Spanning Tree
Algorithm detects a network topology change.
Forwarding: The switch is operating and this interface is forwarding
traffic.
Standby: This interface will not forward any traffic through the switch
because a loop condition has been detected by the STA.

High Speed Interface Configuration Screen (2H23-50R Only)
Current Oper. Mode (Read-only)
This field displays the current operating mode of slots 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 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 slot is empty.
Desired Oper. Mode (Selectable)
This field allows the user to select the desired operational mode for an
interface in slot 5 or 6. The field toggles between 100Base-FX and
100Base-FXFD (full duplex) when an FE-100FX or FE-100F3 is
installed. Section 5.13.1 describes how to configure a port with an
FE-100FX or FE-100F3.
NOTE
In normal operation, the port with an FE-100TX installed
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 5.13.2 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.

Chapter 5: Local Management
Advertised Ability (Selectable)
During auto-negotiation, the FE-100TX informs 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 5.13.2.2 describes
how to enable or disable advertised modes.
5.13.1 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 5.13.1.1 provides instructions for
manually configuring the slot with an FE-100FX or FE-100F3 interface.
5.13.1.1 Setting the FE-100FX or FE-100F3
Operational Mode
Use the Desired Oper. Mode field to set the active technology. This field
toggles between 100Base-FX and 100Base-FXFD (full duplex). To 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 100Base-FX or 100Base-FXFD (full
duplex).

NOTE
The Port Redirect Function screen can only be used if the
operational mode of the device has been set to 802.1D
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 5-22, enables the user to set
each Network, Fast Ethernet, or HSIM port 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. Table 5-6 shows
the port organization.

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.

Port Redirect operates at a switch interface level and not at a repeater port
level. If traffic is redirected to interfaces that include active repeater ports,
then the redirected traffic is transmitted out all of the repeater ports
connected to the interface.

RMON Index (Read-only)
This field displays the current Ethernet interface for which statistics are
being shown. The 2H23-50R or 2H33-37R has an embedded RMON
agent that gathers statistics for each of its interfaces.
Data Source (Read-only)
This field displays the source of the statistics data that is currently being
displayed on the screen. Figure 5-32 shows that the data source for this
RMON index is Interface 1 (Network Port 1, 10 Mbps of CONN 1) by
displaying the name IfIndex.1. If the screen was displaying RMON
statistics for Interface 4 (Network Port 4, 100 Mbps of CONN 2), the
name displayed would be IfIndex.4. Table 5-14 shows the association
between the CONN and Network Ports for the 2H23-50R and 2H33-37R.

Drop Events (Read-only)
This field displays the total number of times that the RMON agent was
forced to discard frames due to the lack of available switch resources.
NOTE
The Drop Events field does not display the number of frames
dropped, it only displays the number of times that the RMON
agent was forced to discard frames. Drop events are a normal
occurrence during switch initialization.
Collisions (Read-only)
This field displays the total number of collisions that have occurred on
this interface.
Broadcast Pkts (Read-only)
The Broadcast Pkts field displays the total number of good frames that
were directed to the broadcast address. The value of this field does not
include multicast frames.
Multicasts (Read-only)
The Multicast field displays the total number of good frames received that
were directed to a multicast address. The value of this field does not
include frames directed to the broadcast address.
CRC Align Errors (Read-only)
This field displays the number of frames with bad Cyclic Redundancy
Checks (CRC) received from the network. The CRC is a 4-byte field in
the data frame that ensures that the data received is the same as the data
that was originally sent.
Undersized Pkts (Read-only)
The Undersized Pkts field displays the number of frames received whose
size was less than the minimum Ethernet frame size of 64 bytes, not
including preamble, but have a valid CRC.

arp:
Syntax:
arp <options>
Description:
The arp command provides access to the ARP
(Address Resolution Protocol) cache, enabling
you to view cache data, delete entries, or add a
static route. Super-user access is required to
delete an entry or add a static route.
Each ARP cache entry lists the network
interface that the device is connected to, the
device’s network address or IP address, the
device’s physical address or MAC address, and
the media type of connection to the device.
Media types display as numbers, which stand
for the following states:
1 - Other
2 - Invalid entry (cannot ping device, timed out,
etc.)
3 - Dynamic route entry
4 - Static route entry (not subject to change)
You can specify the arp command without options, or with one of the
following options:
Options:

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. Do NOT attempt a Forced BootP unless a
BootP server has been configured for the 2H23-50R or 2H33-37R. The
BootP server references the location of a station acting as a Trivial File
Transfer Protocol (TFTP) server containing the image file. When the
position of Switch 6 is changed and the power is cycled to the device,
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 device continues to request either
the BootP server or the TFTP server until the RESET button on the
device is pressed. Once the RESET button is pressed, the device resets
after one minute and loads 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 device resets, you can either use the factory default
settings or reenter your own parameters.
•
Switch 8 – Reset Password/Community names. 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
device resets, you can either use the factory default settings or reenter
your own passwords.
NOTE
