84 LED descriptions
NOTE: See "MSA 2040 SAN" (page 11) for information about supported combinations of host interface
protocols using Converged Network Controller ports.
1
When in FC mode, the SFPs must be a qualified 8 Gb or 16 Gb fibre optic option described in the QuickSpecs.
2
When in 1 Gb iSCSI mode, the SFPs must be a qualified RJ-45 iSCSI option as described in the 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.

Link Status/
Link Activity
Off — No link detected.
Green — The port is connected and the link is up; or the link has I/O or
replication activity.
3Network 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.
See also Cache Status LED details.
10 Expansion Port Status Off — The port is empty or the link is down.
On — The port is connected and the link is up.
