At power-on, check the 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 ops 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.
