A. Is your system an HP 9000 HP-PB? Follow the flowchart path
that corresponds to your system.
B. Check self-test LED. If card operation is normal, the LED will turn
on briefly during power up and then turn off. If the LED never comes
on or stays on after a normal boot-up process, there is a card
problem. If the LED is blinking, the ring speed may have been
incorrectly configured or there may be a network error external to
the card. Refer to the HP-PB Token Ring Network Adapter manual
for more detailed information.
C. Verify lobe cable solidly connected. Without powering down the
system, make sure the connector on your cable is solidly connected to
the card. If the connector has become disconnected, plug it in and
continue.
D. Verify physical connection to TAU or Switch. Make sure that
your Token Ring cable is fully connected to the TAU or Switch and
that the TAU or Switch state is UP.
E. Verify Token Ring network is UP (other than your system).
Make sure that the status of the Token Ring network is UP by
checking the status of some of the other systems on the network, i.e.
ask your co-workers if their systems are operational.
F. Problem solved? If so, stop. If not, continue to G.
G. Is your system an HP 9000 HP-PB? Go to the flowchart
corresponding to your system. For Series 800 HP-PB systems,
continue to flowchart 2. Otherwise, continue to flowchart 2A.
