Chapter 4: Subsystem Operation and Monitoring
1.
Controller module LEDs:
The Ctlr_Status and BBU_Link (if
BBU is installed) LEDs should light constantly green.
2.
Drive tray LEDs:
The green status LEDs on all drive trays that
contain a hard drive should light up showing that power is
supplied to the disk drives. The Drive Busy LEDs should also
start flashing, indicating that system is attempting to access hard
drives.
3.
LEDs on LCD keypad panel:
The blue LED on the LCD keypad
panel should illuminate after a successful initialization process,
indicating that system status is ready. System initialization may
take up to five minutes and the system fault LED may light up
during the process. The system fault LED will turn off after a
successful boot-up process.
4.
SAS port LEDs:
The Link LED near the SAS ports should
illuminate green, indicating successful connection has been
established.
5.
BBU LED:
The LED on the BBU rear panel should start flashing
amber, indicating that the BBU is being charged.
6.
PSU LEDs:
If the PSU is operating normally and experiencing no
problem after power-on, the LEDs on the PSU should light
constant green.
7.
Firmware and RAIDWatch:
Once the subsystem has
successfully initialized, you may examine details of the operating
statuses using the embedded firmware utility or the RAIDWatch
GUI software.
8.
Audible alarm:
If any errors occur during the initialization
process, the onboard alarm will sound in a hastily repeated
manner.
NOTE:
The subsystem has been designed to run continuously. If a
component fails, the fault can be corrected online.
