This section contains FRUs that have LED indicators. Each
listed assembly is shown with a description of its LEDs. Do not use
LEDs as a starting point for diagnosing a problem.

LED off indicates port is not ready.
LED on solid indicates port is ready (link is operational).
Fibre Channel host card port LEDs
Table 5 and
Table 6 provide detailed information on Fibre Channel host card port LEDs.
Important: Do not replace host adapter cards based on visual symptoms that are displayed in the
LEDs. Replace them only when they are:
Listed in a serviceable event FRU list, OR
Isolated in an isolation procedure MAP
Note: In the following tables, LED terms are:
Slow flashes are 1 per second
Fast flashes are 4-5 per second
Flashing is very fast flashing; the LED may look dimly lit
