Problem
FRU/Action
GBIC is installed, only the
green LED is lit, but no
communications occurs
between the devices.
The hub is receiving a
valid Fibre Channel signal
from the end device, but
no upper-level protocols
are active.
1. Verify that the proper
HBA device drivers are
loaded for the
appropriate operating
system and that the
host has been
configured to recognize
the attached disk
devices.
2. Unplug the fiber cable
from the end node and
verify that an optical
signal is present on the
cable receiver lead. If
no signal is present,
the receiver lead of the
cable might be
defective and the
device is streaming
loop-down sequences
to the hub. Replace
the cable.
