storage system may require service.
Error Messages
The front panel of the storage system includes two-digit, seven-segment LEDs.
When operations are normal, the display will show “HP” or the unit
identification number. The LEDs are powered by the internal power supply, and
when the power supply is not working there will be no display.
If the chassis fan in the unit becomes stalled, the display will show “FF” (fan

Immediately power down the storage system. Verify the voltage select switch is

volts in Europe).
