2 Understanding LED Indicator Status

Storage system components have LEDs to indicate status of the hardware and whether or not it is
functioning properly. These indicators help diagnose basic hardware problems. You can quickly
identify hardware problems by examining the LEDs on all components using the tables and
illustrations in this chapter.

Enclosure LEDs

Bezels LEDs

The bezels are located at the front of the system on each side of the drive enclosure and include
three LEDs.
