Ethernet adapter problem Suggested Action
Ethernet Link Status light is
not On. Check the following:
v
Ensure that the hub is powered on.
v
Check all connections at the Ethernet adapter and the hub.

designation.
v
Use another port on the hub.
v
If the hub does not support auto-negotiation, manually configure the Ethernet
adapter to match the hub.
v
If you manually configured the duplex mode, ensure that you also manually
configure the speed.
v
Run diagnostics on the LEDs.
If the problem remains, go to “Starting the diagnostic programs” on page 98 to run
