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 N3700 storage system from the error messages
displayed on your system console.
