Introduction
The Centillion 100 EtherSpeed 10BASE-T/100BASE-FX Switch Module from Bay Networks
®
inserts
into one slot of a Centillion 100
™
chassis. The module provides eight 10BASE-T switched ports that
operate at 10 megabits per second (Mb/s) and two 100BASE-FX switched ports that operate at
100 Mb/s.
This guide contains information specific to the 8/2-port EtherSpeed 10BASE-T/100BASE-FX Switch
Module and includes the following topics:
• Status LED descriptions
• Default configuration
• 100BASE-FX cable requirements
• 10BASE-T port pin assignments
• Technical specifications
• Declaration of Conformity
For information about installing and troubleshooting Centillion 100 EtherSpeed
™
modules, refer to
Using the Centillion 100 EtherSpeed Switch Modules
(Bay Networks part number 893-890-B). Refer
to
Using SpeedView 2.1 for Windows
(Bay Networks part number 893-891-B) for information about
how to use SpeedView
™
to configure features on an EtherSpeed module and a Centillion 100 switch.

Status LEDs
Two banks of status LEDs on the EtherSpeed module correspond to the port numbers on the module
(see Figure 2). Each fiber port has a correspondingly numbered LED.
Figure 2. EtherSpeed 10BASE-T/100BASE-FX Switch Module LEDs
Each numbered LED turns on, turns off, or blinks to indicate link status and/or data activity as
described in Table 1.
Table 1. EtherSpeed LED definitions
LED State Meaning
Turns on Port is enabled from network management, and a cable is attached.
Blinks Data is being transmitted or received.
On (steady, not blinking) Port detects link pulses from the other end, but there is no data.

Fiber Port Requirements
Two SC fiber optic connectors (see Figure 3) on the
EtherSpeed module provide 100BASE-FX
100 Mb/s ports. The 100BASE-FX ports have the
following options and requirements:
• Cable Options
— 62.5-micron multimode fiber optic
— 50/125-micron multimode fiber optic
• Maximum fiber cable length
— 380 meters (1246.4 feet) when operating in
half-duplex mode
— 128 meters (419.84 feet) if one of the FX
ports is connected to a repeater that has FX
ports and TX ports

UTP Port Requirements
The RJ-45 connectors for the 10BASE-T ports accept standard unshielded twisted pair (UTP) cable
and are wired as MDI-X ports to connect end stations without using crossover cables. Use 100-ohm
Category 5 UTP cable with RJ-45 plugs on each end of the UTP cable.
Table 3 shows the pin assignments for 10BASE-T UTP ports in the standard MDI-X configuration.
Figure 4shows the pin assignments for a 10BASE-T Ethernet UTP crossover cable used to connect an
Ethernet hub directly to the EtherSpeed module.
