System components AVA-400, AVA-800 Using LEDs to check the status of the system
3. Use the following table to understand the AltaVault appliance system components on the chassis front:
4. Use the following table to understand the behavior of the system LEDs:
Component Description
Bezel The bezel covers the front of the AltaVault system chassis. From the bottom of the front
bezel, you can see four system LEDs (arranged horizontally) that indicate the status of the
system.
Fan modules There are six redundant and hot-swappable fan modules installed in slots A1 through A3 and
B1 through B3.
The bottom row contains a blank.
You have to remove the front bezel to see the fan modules. The Attention LED is set to
Amber if the fan module is not working properly.
System LEDs The chassis has four LEDs (arranged vertically) that indicate the status of the system:
•Power
• Attention
• Activity A (Controller)
• Activity B (unused in AltaVault)
These LEDs are located behind the bezel. Remove the front bezel to see these LEDs.
The system LEDs and the LEDs visible when the bezel is installed are the same, except that
the bezel LEDs are aligned horizontally and the system LEDs are aligned vertically. Both
sets of LEDs provide the same information about the system.
Chassis handles The chassis has two handles on each side that assist with lifting the system. The handles are
integrated into the chassis and fold flush when not in use.
LED label LED name LED status Description
Power Green
Clear (off)
At least one of the two power supplies (PSUs)
is delivering power to the system.
Neither PSU is delivering power to the system.
Fault (System Attention LED) Amber
Clear (off)
The system is shut down or a fault occurred in
the chassis. The error might be in a PSU, fan,
or controller. The LED also is lit when there is
an internal FRU failure, or the system is in
maintenance mode.
Note: You can check the fault LED on the back
of each controller to see where the problem
occurred.
The system is operating normally.
Activity Blinking green
Clear (off)
The AltaVault OS is running. The length of
time that the light remains on is proportional to
the controller’s activity.
There is no activity on the controller.
