Controller and expansion modules 49
2-When in 1GbE iSCSI mode, the SFPs must be a qualified 1GbE 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.

1-Cables must be qualified HD mini-SAS cable options.
2-Use a qualified SFF-8644 to SFF-8644 cable option when connecting the controller to a 12Gb SAS HBA.
3-Use a qualified SFF-8644 to SFF-8088 cable option when connecting the controller to a 6Gb SAS HBA.

Link Status/
Link Activity
Green — The port is connected and the link is up.
Amber — Partial link exists (one or more lanes down).
Blinking green or amber — Host link activity is detected.
2 OK Green — The controller is operating normally.
Blinking green — System is booting.
Off — The controller module is not OK, or is powered off.
3 Fault Off — The controller is operating normally.
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.
4 OK to Remove Off — The controller is not prepared for removal.
Blue — The controller module is prepared for removal.
5 Identify White — The controller module is being identified.
6 Cache Status Green — Cache is dirty (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.
See also “Cache Status LED details” (page 50).
7 Network Port Activity Status
4
Off — The Ethernet link is not established, or the link is down.
Green — The Ethernet link is up (applies to all negotiated link
speeds).
8 Network Port Link Speed
4
Off — Link is up at 10/100base-T negotiated speeds.
Amber — Link is up and negotiated at 1000base-T.
9 Expansion Port Status Off — The port is empty or the link is down.
Green — The port is connected and the link is up.
