Specifications and recommendations for 100 Mbps cabling
=======================================================

The ATI AT-2560 FX PCI adapters have a choice of SC or ST 
connectors.

This document covers the following topics:

Link integrity
Common problems
      
NOTE: The AT-2560FX PCI/100 operates at 100 Mbps in half- 
and full-duplex modes.


Recommended cables
------------------

The cable must comply with the IEEE 802.3 100BASE-FX standard for 
62.5/125 µm multi-mode fiber cable.

The cable between the computer and the hub must be less than 2000 
meters long for full-duplex operation and 412 meters long for 
half-duplex operation.

The transmit circuit of the network card is connected to the 
receive circuit of the hub and vice versa.

Connecting two workstations without a hub
-----------------------------------------

100BASE-TX uses a star topology. This means a hub or concentrator 
is in the center of a star, and each workstation or server is 
connected to this hub.

For test purposes, you can directly connect two workstations or a
workstation and a server without using a hub.


Link integrity
==============

There are three LEDs on the AT-2560FX PCI adapter:

1. A TX light indicating data packets being transmitted

2. An RX light for data packets being received 

3. An FD light which indicates full-duplex mode

Refer to your adapter Installation Guide or the "Diagnostic LEDs" 
Readme file for complete information.
      


Common problems
===============

A hub can't detect a workstation
--------------------------------

This is often the result of a crossed cable. Make sure the 
wiring is correct. Try switching Tx and Rx and look for a Link
indication on the hub (if there is a Link indicator) or a flashing
Activity indicator on the 2560 (ACT).


Workstations can't connect to the network
-----------------------------------------

Make sure hub port is configured to the correct speed. Also, make 
sure last line in the NET.CFG (NetWare only) file reads:
   
   lastdrive=F (for NETX systems)
   
     or
   
   lastdrive=Z (for VLM systems)

Also try resetting the concentrator or hub or turn the power off 
and on.

If the card transmits but does not receive, try running diagnostics 
software to check if the interrupt is in a conflict.


Check frome types (NetWare only)--must be the same type on the 
workstation as on the server.

Check protocols on both workstation and server

Use Initiator/Responder to test communications
