Powering On/Off StorSimple Appliance v2.0.1

Last modified

Overview

Powering on/off an appliance is not required as a part of normal system operation. Powering on may be required for a brand new appliance or for an appliance that had to be shutdown. Powering off or shutdown are common generally in cases where failed hardware requires replacement, the unit is being physically moved or when taking an appliance out of service.

The following article documents the proper procedure required to power on/off your StorSimple appliance in different scenarios.
