Introduction

The Centillion 100 EtherSpeed 10B ASE-T/100B ASE-FX Switch Module from Bay Netw orks® 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.

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 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.
able 3 shows the pin assignments for 10BASE-T UTP ports in the standard MDI-X configuration.
