outlet.

Checking the Power Connection

WARNING
The Power button on the Front Control Panel of the server does not
completely remove AC power. To completely remove AC power from
the server, you must unplug/disconnect the power connection from the
system. Unplugging/disconnecting the power connection removes the
+12 Volt standby power that is present when the server is powered
down.
WARNING
Do not modify or use a supplied AC power cord if it is not the exact type
required in the region where the server will be installed and used.
Replace the cord with the correct type. Refer to the cord requirements
described below.
Do not connect power to the server (AC or DC) if you will be adding
internal parts (boards, DIMMs, removable media drives). For these
installation procedures, see the cc2300 Carrier Grade Server Product
Guide.
WARNING
The DC power source may produce hazardous voltage levels
exceeding -60 VDC and high energy levels above 240VA that may cause
electric shock or burns. All DC input connections should be made only
by a qualified service person only to prevent injury. All wiring
terminals connected to the DC input terminal block must be fully
insulated with no exposed bare metal.
If an AC power supply is installed:
