This section contains troubleshooting guidelines for systems running
Windows 95, 98, 2000, Me, NT, or XP.
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.
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.)
