SAFETY INFORMATION

CLASS 1 LASER TRANSCEIVERS

THE FE-100F3 FAST ETHERNET INTERFACE MODULE, FPIM-05 AND

FPIM-07 FDDI PORT INTERFACE MODULES, AND APIM-29 ATM

PORT INTERFACE MODULE USE CLASS 1 LASER TRANSCEIVERS.

READ THE FOLLOWING SAFETY INFORMATION BEFORE

INSTALLING OR OPERATING THESE MODULES.

The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This
control loop eliminates the need for maintenance checks or adjustments. The output is factory set, and
does not allow any user adjustment. Class 1 Laser transceivers comply with the following safety
standards:

• 21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).

• IEC Publication 825 (International Electrotechnical Commission).

• CENELEC EN 60825 (European Committee for Electrotechnical Standardization).
When operating within their performance limitations, laser transceiver output meets the Class 1

accessible emission limit of all three standards. Class 1 levels of laser radiation are not considered
hazardous.

SAFETY INFORMATION

CLASS 1 LASER TRANSCEIVERS

LASER RADIATION AND CONNECTORS

When the connector is in place, all laser radiation remains within the fiber. The maximum amount of
radiant power exiting the fiber (under normal conditions) is -12.6 dBm or 55 x 10-6 watts.

Removing the optical connector from the transceiver allows laser radiation to emit directly from the
optical port. The maximum radiance from the optical port (under worst case conditions) is

0.8 W cm-2 or 8 x 103 W m2 sr-1.

Do not use optical instruments to view the laser output. The use of optical instruments to view
laser output increases eye hazard. When viewing the output optical port, power must be
removed from the network adapter.

Overview

1.3 OVERVIEW

The 6H123-50 and 6H133-37, shown in Figure 1-1, are interface modules
for the Cabletron Systems 6C105 SmartSwitch 6000 chassis.

The 6H123-50 and 6H133-37 are high-speed network repeater/switch
devices. The 6H123-50 provides four Ethernet repeated segments and
four Fast Ethernet repeated segments (CONN 1 through CONN 4). The
6H133-37 provides three Ethernet repeated segments and three Fast
Ethernet repeated segments (CONN 1 through CONN 3). 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) segment. Each
Ethernet and Fast Ethernet segment supports 802.1D switching
(bridging), Cabletron Systems SecureFast Switching Virtual Network
technology and IEEE 802.1Q Port Based VLANs.

Slots 5 and 6 (interfaces 9 and 10) of the 6H123-50 support optional Fast
Ethernet Interface Modules providing uplinks to 100BASE-TX or
100BASE-FX Fast Ethernet networks. The 6H133-37 is capable of being
equipped with a High Speed Interface Module (HSIM) that provides for
additional connectivity to other high speed networking technologies such
as Asynchronous Transfer Mode (ATM), Fiber Distributed Data Interface
(FDDI) and Wide Area Network (WANs).

The 6H123-50 and 6H133-37 switch each Ethernet and Fast Ethernet
segment (CONN 1 through CONN 4 and CONN 1 through CONN 3) to
one another and to the optional Fast Ethernet Interface modules of the
6H123-50 or an HSIM installed in the 6H133-37.

1.3.1 Connectivity

The 6H123-50 and 6H133-37 connect to Ethernet/Fast Ethernet networks
or workstations through RJ21 ports on the front panel. Each port supports
a 25-pair cable at lengths up to 100 meters (each pair must be Category 5
compliant with an impedance of 85 to 111 ohms). The ports are IEEE

802.3 10BASE-T and IEEE 802.3u 100BASE-TX compliant.
The 6H123-50 has two front panel slots (connectors 5 and 6 or interfaces

9 and 10) for optional Fast Ethernet Interface Modules to support an
uplink to Fast Ethernet backbones or a high speed connection to a local
server.

The 6H133-37 has one front panel slot for an optional High Speed
Interface Module (Interface 7) to provide for additional connectivity to
other high speed networking technologies such as ATM, FDDI, and
WANs.

Cables available for 100BASE-TX operation include the following:

•

180° angle connector (straight-through RJ21-to-RJ21)

•

180° RJ21-to-RJ45 connector

•

120° angle connector with the same options

6H123-50 and 6H133-37 User’s Guide 1-5

Chapter 1:

Introduction

1.3.2 Full Duplex Switched Ethernet

The optional Fast Ethernet Interface Modules for the 6H123-50 can be
configured to operate in Full Duplex Switched Ethernet mode, which
provides up to 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 6H123-50 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.

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.

1.3.5 Management

Management of the 6H123-50 and 6H133-37 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 6H123-50 and
6H133-37 and any of the optional Fast Ethernet Interface Modules
installed in slots 5 and 6 of the 6H123-50, or an optional High Speed
Interface Module (HSIM) in a 6H133-37.

The associated HSIM user’s guide provides detailed information about
the HSIM Local Management.

1.3.6 Switching Options

The 6H123-50 and 6H133-37 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 6H123-50 or an HSIM installed in a 6H133-37.

IEEE 802.1Q switching and SecureFast switching allow for future
migration to Virtual Network technologies without requiring the
replacement of existing equipment.

1.3.7 Standards Compatibility

The 6H123-50 and 6H133-37 are fully compliant with the IEEE 802.3
standard and the IEEE 802.3u standard. The optional Fast Ethernet
Interface Modules are fully compliant with the IEEE 802.3u standard.
The 6H123-50 and 6H133-37 provide IEEE 802.1D Spanning Tree
Algorithm (STA) support to enhance the overall reliability of the network
and protect against “loop” conditions. The 6H123-50 and 6H133-37
support 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.

1.3.8 LANVIEW Diagnostic LEDs

LANVIEW diagnostic LEDs serve as an important troubleshooting aid by
providing an easy way to observe the status of indi vidual ports and ov erall
network operations. Chapter 4 provides details about the 6H123-50 and
6H133-37 LANVIEW LEDs.

1.3.9 Year 2000 Compliant

These products have an internal clock that can maintain the current time
and date beyond the year 1999.

1.3.10 Runtime IP Address Discovery

This feature enables the 6H123-50 and 6H133-37 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 6H123-50 and the 6H133-37 are connected to the network and
powered up, Runtime IP Address Discovery (RAD) checks the 6H123-50
and the 6H133-37 for an IP address. If one has not yet been assigned
(6H123-50 and 6H133-37 IP address set to 0.0.0.0), RAD checks to see if
any of the 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.

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.

3.5.3 Connecting a Fiber Optic Segment to the
FE-100FX and FE-100F3

The FE-100FX and FE-100F3 have an SC style network port (see

Figure 3-4). Cabletron Systems supplies fiber optic cable that uses SC

style connectors that are keyed to ensure proper crossing over of the
transmit and receive fibers.

An odd number of crossovers (preferably one) must be

!

CAUTION

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.

The FE-100F3 uses Class 1 lasers. Do not use optical

CAUTION

instruments to view the laser output. The use of optical
instruments to view laser output increases eye hazard. When
viewing the output optical port, remove power from the netw ork
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 isoprop yl alcohol may also be used
to clean the fiber optic ends.

2. Insert one end of the SC connector into the FE-100FX or FE-100F3

installed in the 6H123-50. See Figure 3-4.

3. At the other end of the fiber optic cable, attach the SC connector to the

other device.

5.3.4 Monitoring 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

The following briefly defines each Chassis Configuration screen field:

MAC Address (Read-Only)

Displays the physical address of the chassis.

Chassis IP Address (Modifiable)

This field enables the IP address to be set for the 6C105 chassis. If an IP
address is assigned to the 6C105 chassis all the interface modules
installed in the chassis can be managed via this IP address, eliminating the
need to assign an IP address to each interface module. To set the IP
address, refer to Section 5.7.2.

5-18 6H123-50 and 6H133-37 User’s Guide

Chassis Configuration Screen

Subnet Mask (Modifiable)

When a valid IP address is assigned, the Subnet Mask field

NOTE

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 to the
default value. Refer to your Release Notes to ensure that the
Subnet Mask is a modifiable field.

Displays the subnet mask for the chassis. A subnet mask “masks out” the
network bits of the IP address by setting the bits in the mask to 1 when the
network treats the corresponding bits in the IP address as part of the
network or subnetwork address, or to 0 if the corresponding bit identifies
the host. The 6C105 chassis automatically uses the default subnet mask
that corresponds to the IP class that was entered in the IP address field.

Chassis Date (Modifiable)

Contains a value that the chassis recognizes as the current date. When the
chassis date is modified and saved 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 LM 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.

6H123-50 and 6H133-37 User’s Guide 5-19

Chapter 5: Local Management

Screen Lockout Time (Modifiable)

Contains the maximum number of minutes that the Local Management
application displays a module’s screen while awaiting input or action
from a user. For example, if the number 5 is entered in this field, the user
has up to five minutes to respond to each of the specified module’s Local
Management screens. In this example, after five minutes of “idleness” (no
input or action), the terminal “beeps” five times, the Local Management
application terminates the session, and the display returns to the Password
screen. To enter a new lockout time, refer to Section 5.7.6.

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 (Selectable)

This field enables the user to set the 6H123-50 and 6H133-37 to operate
as an 802.1D switch (Switching option), as a Cabletron Systems
SecureFast switch (SFPS VLAN option) or as an 802.1Q switch.

The 12 ports located in each RJ21 interface (CONN 1 through 4 and
CONN 1 through 3) are repeater ports, and each Ethernet network, Fast
Ethernet network, Fast Ethernet Interface Module, and HSIM port(s) may
be bridged to each other.

When the operational mode is set to SFPS VLAN, the 6H123-50 and
6H133-37 act as SecureFast switches. When the Operational Mode is set
to 802.1Q switch the 6H123-50 and 6H133-37 are able to increase their
switching functionality by creating and maintaining 802.1Q V irtual LANs
(VLANs).

5.11 PORT REDIRECT FUNCTION SCREEN

The Port Redirect Function screen, Figure 5-14, enables the user to set
each one of the modules in the chassis (1 through 5), and the interfaces
(bridge ports) of the corresponding module installed, as a source or
destination interface. An interface can be set to have one or more
destination interface and chassis module slot numbers.

For example, interface (port) 1 in module (slot) 1 can be set as a source
interface with three destinations, interfaces 2, 3, and 4 in module (slot) 3.
Traffic from interface 1 in module 1 is then automatically redirected to
interfaces 2, 3, and 4 in module 3. Interface 1 in module 1 can also serve
as a destination interface for other interfaces and modules. The port
redirect function is extremely useful for troubleshooting purposes, as it
allows traffic to be sent to a particular interface(s) where, with the use of
an analyzer or RMON probe, all current traffic from the source
interface(s) can be examined.

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

NOTES

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

Although traffic from the source interface (including, if desired,
errored frames) is sent to the destination interface, normal
switching is still performed for all frames on the source
interface.

Access the Port Redirect Function screen from the Chassis Menu screen
by using the arrow keys to highlight the PORT REDIRECT
FUNCTION menu item and pressing ENTER. The Port Redirect
Function screen, Figure 5-14, displays.
