Installing and Replacing the Power Supply

The following steps show how to install a new supply or replace a failed
supply.
Power does not have to be turned off on a working supply to add a new supply
or replace a failed one.
Step
1 One Power Supply
If only one supply is installed in the chassis, remove the
blank panel covering the unused power supply slot.
Two Power Supplies
If two power supplies are installed, the failed supply can be
identified by the alarm on the front panel LCD. The alarm
message will identify a failure on Power Supply A or Power
Supply B. The option slot legend on the rear panel shows the
location of each power supply. Turn the power switch to Off
on the failed supply and unplug the power cord from the
power source.
2 Remove the two screws that secure the power supply mod-
ule to the TSU 600e chassis and remove the failed power sup-
ply module.
3 Remove the new power supply from the shipping con-
tainer. Make sure the power switch is in the Off position.
4 Plug the new supply into the open power supply slot and
install the two screws on the power supply module
5 Plug the new power supply cord into a grounded 115 VAC,
50/60 Hz power receptable.
6 Turn the power switch On.
