Turning Power On And Off - Dell EqualLogic FS7610 Series Hardware Owner's Manual

Dell EqualLogic FS7610 Hardware Owner's Manual
The appliance turns on as soon as the power supplies are connected to a live power source.
Each controller contains a backup power supply (BPS). The BPS batteries begin to charge when the
appliance is connected to power. A full charge takes up to eight hours to complete; the NAS
appliance is not fully redundant until the battery is fully charged. The BPS provides the clustered
solution enough time to write all cached data to disk if the controller experiences a loss of power.

Turning Power On and Off

Normally, the appliance turns on when the power cables are connected to a source of live power. An LED
indicator on the front of the appliance indicates if power is supplied to the appliance and if the appliance is
operational. However, each controller has a power button on its back (the power LED) that enables you to turn
off power to an individual controller for service purposes.
In addition, the power supplies have an LED that shows if power is present or if a power fault has occurred, as
described in Table 5.
