5 Understanding F-Class Storage System LED Status
Using the F-Class Component LEDs
The F-Class Storage System components have LEDs to indicate whether or not the hardware is
functioning properly and to help identify errors. These LEDs help diagnose basic hardware problems.
You can quickly identify hardware problems by examining the LEDs on all the components and
using the following tables and illustrations in this chapter.
If you detect any problems during inspection of the LEDs, contact your Authorized Service Provider.
Bezel LEDs
LEDs are located at the front of the F-Class Storage System on the bezel for quick assessment of
