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.
4-When port is down, both LEDs are off.

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.

Green — The Ethernet link is up (applies to all negotiated link
speeds).
