The power supplies will continue to provide standby current to the NetServer until
the power cable is disconnected.
In the rack-mounted version, the I/O is under the top cover, in the pedestal version,
the I/O is under the left cover.
Always disconnect the power cords before removing the covers, to avoid exposure
to high energy levels that may cause burns when parts are short-circuited by metal
objects such as tools or jewelry. Disconnect any telephone cables to avoid exposure
to shock hazard from telephone ringing voltages.
