Monitoring the front operation panel

About monitoring the front operation panel

The front operation panel has five LEDs and a disk shelf ID display. The LEDs indicate whether your disk shelf is functioning normally or there are problems with the hardware. You can also identify any hardware failure associated with the front operation panel of the disk shelf from the error messages displayed on your storage appliance console.

Location of LEDs

The following illustration shows the location of the disk shelf ID display and the front panel LEDs.

Note
The Fault and System LEDs are amber. The other three LEDs are green. See Interpreting the front panel LEDs for an illustrated explanation of how the LEDs function.

Monitoring the disk shelf ID

When you use the thumbwheel switch on the back of the disk shelf to change the disk shelf ID, the disk shelf ID display on the front panel blinks until you power-cycle the disk shelf to make the change take effect.
