System overview
4-When port is down, both LEDs are off.
Figure 40 LEDs: DS2200 FC/iSCSI controller modules (FC or 10GbE SFPs)
1-When in FC mode, the SFPs must be a qualified 8Gb or 16Gb fiber optic option. A 16Gb/s SFP can run at 16Gb/s, 8Gb/s, 4Gb/s, or
auto-negotiate its link speed. An 8Gb/s SFP can run at 8Gb/s, 4Gb/s, or auto-negotiate its link speed.

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
OK
Green — The controller is operating normally.
Blinking green — System is booting.
Off — The controller module is not OK, or is powered off.
4
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.
5
OK to Remove
Off — The controller is not prepared for removal.
Blue — The controller module is prepared for removal.
6
Identify
White — The controller module is being identified.
7
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.

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).
9
Network Port Link Speed
4
Off — Link is up at 10/100base-T negotiated speeds.
Amber — Link is up and negotiated at 1000base-T.
10
Expansion Port Status
Off — The port is empty or the link is down.
Green — The port is connected and the link is up.
