122 QXS G2 Hardware Installation and Maintenance Guide
Table 16 provides the RAID chassis controller LED states.
Actions:
• If the CRU OK LED is blinking, wait for the system to boot.
• If the CRU OK LED is off, and the controller is powered on, the module has failed.
• Check that the controller is fully inserted and latched in place, and that the chassis is powered
on.
• Check the event log for specific information regarding the failure.
• If the CRU Fault LED is on, a fault condition is detected.
• Restart this controller from the partner controller using the disk management utility or CLI.
• If the restart does not resolve the fault, remove the controller and reinsert it.
• If the above actions do not resolve the fault, contact your supplier for assistance. Controller
replacement may be necessary.
5 OK to Remove Off — The controller is not prepared for removal.
Blue — The controller module is prepared for removal.
6 Identity White — The controller module is being identified.
7
Cache Status
4
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.
8 Network Port Activity
Status
5
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
5
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.
