NOTE: Once a Link Status LED is lit, it remains so, even if the controller is shutdown via the SMU or CLI.
When a controller is shutdown or otherwise rendered inactive—its Link Status LED remains illuminated—falsely
indicating that the controller can communicate with the host. Though a link exists between the host and the chip on the
controller, the controller is not communicating with the chip. To reset the LED, the controller must be properly
power-cycled [see "Powering on/powering off" (page

Definition
Off — No link detected.
Green — The port is connected and the link is up.
Off — The link is idle.
Blinking green — The link has I/O activity.

2
Off — Link is up at 10/100base-T negotiated speeds.
Amber — Link is up and negotiated at 1000base-T.
Off — The controller module is not prepared for removal.
Blue — The controller module is prepared for removal.
Off — Normal operation.
Blinking white — Physically identifies the controller module.
Off — Controller module is not OK.
Blinking green — System is booting.
Green — Controller module 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.
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.

Off — The port is empty or the link is down.
