Checking AC Power and Storage System Status for the Tower

The “Power on” LED on the ESI/ops panel (see Figure 2-2) turns green if AC power is

present.

Figure 2-2 ESI/Ops Panel LEDs and Switches

At power-on, check ESI/ops panel LEDs for system status. Under normal conditions, the

“Power on” LED should illuminate constant green. If a problem is detected, the ESI

processor in the operator panel will illuminate the “System/ESI fault” LED in amber. See

“Solving Initial Startup Problems” on page 76 and “Using Storage System LEDs for

Troubleshooting” on page 78.
