To connect the power cord 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".)
To control power supply with an application (ESMPRO UPS Controller) that controls the UPS, connect the power cord
to a SWITCH OUT outlet.
For constant power supply, connect the power cord to an UN-SWITCH OUT outlet. (Plug a modem that has a
permanent connection to this outlet.)

When the power cord is connected from the server to a UPS, change the BIOS setup of the server to link with power
supply from the UPS.
Change a parameter for "AC-LINK" under the Server menu of the BIOS setup utility. See Chapter 4 for details.
