If this indicator is lit, immediately turn off the ac power switch on the
bottom rear of the storage enclosure. Call Digital Customer Services.
If the green fault indicator is not on, proceed as follows:
a. Check for an overload current condition in the power supply by
turning off all drive dc power switches on the front panel. (Refer
to Figure 4–2). If the enclosure fan starts, go to step 2 (recovery
when drive dc power switches are blinking).
