MSA 2050 SAN controller module—rear panel LEDs
1
When in FC mode, the SFPs must be a qualified 8 Gb or 16 Gb fibre optic option described in the QuickSpecs. A 16 Gb/s SFP can run at 16 Gb/s, 8 Gb/s,
4 Gb/s, or auto-negotiate its link speed. An 8 Gb/s SFP can run at 8 Gb/s, 4 Gb/s, or auto-negotiate its link speed.
2
When in 10GbE iSCSI mode, the SFPs must be a qualified 10GbE iSCSI optic option as described in the QuickSpecs.
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.

Description
Definition
1
Host 4/8/16 Gb FC
1
Link Status/
Link Activity
Off — No link detected.
Green — The port is connected and the link is up.
Blinking green — The link has I/O or replication activity.
2
Host 10GbE iSCSI
2,3
Link Status/
Link Activity
Off — No link detected.
Green — The port is connected and the link is up.
Blinking green — The link has I/O or replication activity.
3
Network Port Link
Active 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).
4
Network Port Link Speed
4
Off — Link is up at 10/100base-T negotiated speeds.
Amber — Link is up and negotiated at 1000base-T.
5
OK to Remove
Off — The controller module is not prepared for removal.
Blue — The controller module is prepared for removal.
6
Unit Locator
Off — Normal operation.
Blinking white — Physically identifies the controller module.
7
FRU OK
Off — Controller module is not OK.
Blinking green — System is booting.
Green — Controller module is operating normally.
8
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.
