I/O enclosure LED indicators (Models 951, 95E)

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.

5	Identify for I/O enclosure PCI slot	P1-Cx	amber	normal	n/a	identify
6	Activity for I/O enclosure device adapter card port	P1-Cx-Ty x=3, 6	green	not ready Note 1	ready Note 2	n/a
7	Identify for I/O enclosure device adapter card port	P1-Cx-Ty x=3, 6	amber	normal	n/a	identify
8, 9	Fibre channel host card port LEDs (see Table 5 and Table 6)	P1-Cx-Ty x=1,4

Notes:

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 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 blinks are 1 per second
Fast blinks are 4 per second
Flashing is very fast blinking; the, LED may look dimly lit

Table 5. Fibre channel host card port LEDs (normal conditions)
Adapter	Yellow LED	Green LED	State
8-Gb/s adapters	Off	Slow blink	Normal - link is down or not started
	2 blinks	On	2-Gb/s link rate - normal, link is up
	3 blinks	On	4-Gb/s link rate - normal, link is up
	4 blinks	On	8-Gb/s link rate - normal, link is up

Adapter	Yellow LED	Green LED	State
8-Gb/s adapters	Off	Off	Wake-up failure (dead board)
	Off	On	Failure when functioning
	On	Off	POST failure (dead board)
	On	On	Failure when functioning
	Slow blink	Off	Wake-up failure monitor
	Slow blink	Slow blink	Offline for download
	Fast blink	Off	POST failure
	Fast blink	Slow blink	Restricted offline mode (waiting for restart)
	Flashing	Off	POST process in progress
	Flashing	Slow blink	Restricted offline mode (test active)
