Troubleshooting the Ethernet controller

This section provides troubleshooting information for
problems that might occur with the 10/100 Mbps Ethernet
controller.

Network connection problems

If the Ethernet controller cannot connect to the network,
check the following:
v Make sure that the cable is installed correctly.
The network cable must be securely attached at all
connections. If the cable is attached but the problem
persists, try a different cable.
If you set the Ethernet controller to operate at 100
Mbps, you must use Category 5 cabling.
If you directly connect two workstations (without a hub),
or if you are not using a hub with X ports, use a
crossover cable.
Note: To determine whether a hub has an X port, check
the port label. If the label contains an X, the hub
has an X port.
v Determine if the hub supports auto-negotiation. If not, try
configuring the integrated Ethernet controller manually to
match the speed and duplex mode of the hub.
v Check the Ethernet controller lights on the operator
information panel.
These lights indicate whether a problem exists with the
connector, cable, or hub.
– The Ethernet Link Status light illuminates when the
Ethernet controller receives a LINK pulse from the
hub. If the light is off, there might be a bad connector
or cable, or a problem with the hub.
– The Ethernet Transmit/Receive Activity light
illuminates when the Ethernet controller sends or
receives data over the Ethernet Network. If the
Ethernet Transmit/Receive Activity light is off, make
