Color Indication
Amber When this LED is lit, it indicates that the battery
cannot sustain the RAID controller memory in
case of power loss. This might be caused by any
of the following conditions:
v The battery is removed.
v There is a battery-charger circuit failure.
v The battery temperature is too high.
v The battery voltage is out of range.
v The battery charge current is out of range.
When this LED is off, it indicates that the battery
can sustain the RAID controller memory in case
of a power loss.
Amber When this LED is lit, it indicates that there is
data in the cache that has not been written to a
disk or synchronized to the redundant controller
cache.
Amber When this LED is lit, it indicates that the XScale
memory has failed. This is based on one of the
following conditions:
v Cannot read the DIMM configuration data
v Nonrecoverable ECC failure
When this LED is off, it indicates that the XScale
memory is operating normally.
Amber When this LED is lit, it indicates that the cache
memory has failed. This is based on one of the
following conditions:
v Cannot read the DIMM configuration data
v Nonrecoverable ECC failure
When this LED is off, it indicates that the cache
memory is operating normally.
Amber When this LED is lit, it indicates that the
controller is not ready.
Green When this LED is lit, it indicates that the Gb
Ethernet link is operational.
Green When this LED is lit, it indicates that data
