Table 5-1 Symptoms and Actions

Symptom Action

Card fails power-up test. • Inspect the LEDs on the back of the adapter. A

constant, solid LED (4) indicates a failure in the

power-up diagnostics. For HSC FDDI, solid LEDs (2)

and (3) indicate power-up diagnostics succeeded. For

EISA FDDI, solid LEDs (1) and (3) indicate power-up

diagnostics succeeded. If power-up diagnostics fail,

turn the power off, reseat the adapter, then turn the

power back on.

• Try another EISA or HSC slot.

• Swap adapter with another which is known to

operate.

Adapter does not respond. • Use the ifconfig command to check the existence

and status of the device. For example:

ifconfig lan0

• Verify that the host to IP mapping is known to the

local system by either doing an nslookup on the

host name or by checking the /etc/hosts ﬁle.

• Verify that the FDDI cable is properly connected at

both ends.

ioscan output shows that the

adapter is unclaimed.

Check that the driver software is loaded.
