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. It is also lit during the initialization process.
ON indicates the following:
- Cache Memory is dirty.
- Data in flash backup module is being flushed to cache.
- Errors occurred with cache memory (ECC errors).
- Data is being flushed from flash backup module to
drive (when power is restored).
- Battery voltage is lower than 2.5V.
- Battery temperature reading is abnormal (out of the 0
to 45°C range).
- Battery is not present.
Blinking indicates that the system is writing cached data
from cache memory to flash backup during power
outage. Once done, LED is turned off.
OFF indicates that the cache is clean, and that the
battery backup unit is capable of sustaining memory in
case of power loss.
This signal is local to each controller.
ON 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.
Green steady on indicates the CBM module is ready.
Both a BBU and flash modules are present. Fast blinking
indicates BBU is charging.
Amber steady on indicates CBM failure, meaning either
BBU or flash has failed. When lit, it also indicates either
BBU or a flash is missing in a redundant-controller
system.
Blinking means a BBU is being charged.
OFF means CBM is not installed in a single-controller "G"
model.
