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 system is functioning normally or whether there are problems with the hardware. You can also identify any hardware failure associated with the front operation panel of the appliance from the error messages displayed on your system console.
