Monitoring
Name Color Status
1. Ctrl Status Green/Amber
Green indicates that a RAID controller is operating
healthily.
Amber indicates that a component failure has
occurred, or inappropriate RAID configurations have
caused system faults. This LED is also lit during the
initialization process.
2. C_Dirty Amber
Amber indicates the following:
– Cache memory is dirty.
– Data in FBM is being flushed to the cache.
– Errors have occurred with cache memory
(ECC errors).
– Data is being flushed from the flash backup
module to the drive (when power is restored).
– Battery voltage is lower than 2.5V.
– Battery temperature reading is abnormal
(outside the 0 to 45 °C range).
– Battery is not present.
Off indicates that the cache is clean, and that the
BBU is capable of sustaining memory in case of power
loss.
Blinking amber indicates that cached data is being
transferred to the flash module after the occurrence of
a power outage. Once the transfer is complete, all
LEDs will turn off.
This signal is local to each controller.
3. Temp. Amber
Amber indicates that the detected CPU/board/chassis
temperature has exceeded the higher temperature
threshold.
Off indicates that the detected temperature reading is
within the safe range.
4. CBM Status Green/Amber
Green steady on indicates the CBM module is ready.
Both BBU and flash modules are present.
Amber steady on indicates CBM failure, meaning either
the BBU or flash has failed. When lit, either the BBU or
a flash module is missing in a redundant-controller
system.
Blinking means a BBU is being charged.
Off means BBU is not installed in a single-controller “G”
model.
5. Hst Bsy Green Blinking green indicates traffic on the host bus.
6. Drv Bsy Green Blinking green indicates traffic on the drive channels.
7. Restore Default Green
Green indicates the RAID configuration default has
been successfully restored. The LED state will be
invalidated after a few seconds.
