General Troubleshooting Guidelines
This section contains troubleshooting guidelines for systems running
Windows 95, 98, 2000, Me, NT, or XP.
Suggestions Here are a few general troubleshooting suggestions:
❑ Check to be sure that the adapter card is completely seated in the
PCI slot in the computer.
❑ Check that the cable is securely connected to the adapter card
and to the remote Ethernet hub or switch.
❑ Verify that the remote Ethernet hub or switch is powered ON and
is operating properly.
❑ Verify that the PCI slot containing the adapter card is Bus Master
enabled. Refer to your computer’s documentation for further
information.
❑ Make sure that the adapter driver is loaded and the protocols are
bound.
Twisted Pair
Adapter Cards
Below are guidelines for troubleshooting an adapter card that has a
twisted pair port.
❑ Check to be sure that you are using the correct type of cabling:
— Category 3 or better 100 ohm twisted pair cable for 10 Mbps
— Category 5 or better 100 ohm twisted pair cable for 100 Mbps
— Category 5 and 5E 100 ohm twisted pair cable for 1000 Mbps
❑ Verify that the maximum operating distance for the adapter card
has not been exceed. The maximum operating distance for a
twisted pair port is 100 meters (328 feet).
❑ Check that the twisted pair cable is securely connected to the
adapter card and to the remote Ethernet hub or switch.
❑ Determine if a crossover cable is required when connecting the
adapter card to the remote Ethernet hub or switch. A 10 or 100
Mbps twisted pair port on an Allied Telesyn adapter card is
configured MDI-X. If the port on the remote Ethernet hub or
switch is MDI, use a straight-through twisted pair cable to connect
the adapter card. If the port on the remote Ethernet hub or switch
is MDI-X, use a crossover cable. (If the port on the remote Ethernet
hub or switch is auto MDI/MDI-X, you can use either a straight-
through or crossover cable.)
