Powering Down the Device
System power in the StorageWorks NAS B2000 does not completely shut off with the front
panel Power On/Standby button. The button toggles between on and standby modes, rather
than on and off. The standby position removes power from most electronics and the drives,
but portions of the power supply and some internal circuitry remain active. To completely
remove all power from the system, you must disconnect all power cords from the device.
WARNING:
To reduce the risk of injury from electrical shock,
remove the power cords to completely disconnect power
from the system.
CAUTION:
Electrostatic discharge can damage electronic components. Be
sure you are properly grounded before beginning any installation procedure.
