Insert the power cords to the AC inlets of the power unit.
Then, secure the power cords using the locking springs on the power units.
When completing connection to peripheral equipment, connect the two provided power cords to the server. After that,
secure the cables with the cable tie provided in the server.
Connect the plug at the other end of the power cord to a wall outlet with parallel double-pole grounds provided or to an
uninterruptible power supply (UPS).
To use the functions of the server, you should connect the server to the UPS.

IMPORTANT:
Be sure to use both power cords to make the server fault-tolerant.
After connecting the power cords, wait at least 30 seconds before pressing the power switch.
To connect the power cords from the server to an uninterruptible power supply
(UPS), use service outlets on the rear of the UPS.
The UPS service outlets are categorized into two groups: SWITCH OUT and
UN-SWITCH OUT. (They may be called "OUTPUT1" and "OUTPUT2".)
For constant power supply, connect the power cords to a UN-SWITCH OUT
outlet. (Connect the modem that is in service for 24 hours to this outlet.)
When the power cords from the server are connected to a UPS, change the
BIOS setup of the server to link with power supply from the UPS.
Select [AC-LINK] from [Server] on the BIOS setup utility and change
parameters. See the separate volume of User's Guide for details.
