Link Status Lights

If

a

fault

occurs that

prevents

the

operation

of a

particular

link, the link status li

the

various

parts

of

the

complete

link

show that

the

error has

occurred.

You

can

find

the

failing

link

by

looking

for

the

flashing green

status light at each e

the affected link. Some configurations might have

other indicators

along the link (for

example,

SSA connector

cards) to

help

with FRU

isolation.

The meanings of the disk drive and adapter lights are summarized here.
