Redundant Power Upgrade Kit Installation Procedures
4.
Ensure that both power supplies have their line voltage selector switch set to
the same voltage (see the following figure).
!
CAUTION
Before you plug the system power cord into an AC outlet,
ensure the input line voltage setting for the power supply is
correct.
To use the system with line source voltages between 200
and 240 VAC, the line voltage selector switch on the power
supply must be set to 230. If you set the switch to the 115
VAC position, the power supply will be damaged when you
plug in your system.
When two power supplies are installed in the system both
power supplies must have their line voltage selector switch
set to the same voltage.
If you need to change the line voltage setting, perform the following steps.
1.
Unplug the AC power cord from the back of the chassis.
2.
Insert the tip of a small screwdriver or ballpoint pen into the depression on
the line voltage selector.
3.
Slide the selector switch to 115 VAC or to 230 VAC (line source voltage
range: 220 to 240 VAC).
