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
“
LED status on the front operation panel
” on page 9 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.
