LED descriptions
1
When in FC mode, the SFPs must be a qualified 8 Gb fibre optic option described in QuickSpecs.
2
When in 1 Gb iSCSI mode, the SFPs must be a qualified RJ-45 iSCSI option as described in QuickSpecs. The 1 Gb iSCSI mode does
not support an iSCSI optic option.
3
When powering up and booting, iSCSI LEDs will be on/blinking momentarily, then they will switch to the mode of operation.
4
When port is down, both LEDs are off.

Fault/Service Required
Amber — A fault has been detected or a service action is required.
Blinking amber — Hardware-controlled power-up or a cache flush or restore
error.
9
Cache Status
Green — Cache contains unwritten data and operation is normal. The
unwritten information can be log or debug data that remains in the cache, so
a Green cache status LED does not, by itself, indicate that any user data is at
risk or that any action is necessary.
Off — In a working controller, cache is clean (contains no unwritten data).
This is an occasional condition that occurs while the system is booting.
Blinking green — A CompactFlash flush or cache self-refresh is in progress,
indicating cache activity.
