The optional redundant power supplies are accessible from the back panel.
Removing a Redundant Power Supply
CAUTION:
To prevent risk of personal injury from electrical shock, do not reach into an empty power
supply bay.
NOTICE:
The power supplies are hot-pluggable. The system requires one power supply to be installed
for the system to operate normally. The system is in the redundant mode when two power supplies are
installed. Remove and replace only one power supply at a time in a system that is powered on.
1 Disconnect the power cord from the power supply.
2 Press the spring tab that secures the power supply handle, and then pull the handle outward
to release the power supply. See Figure 6-2.
3 Slide the power supply out of the chassis.
Installing a Redundant Power Supply
1 Slide the power supply into the chassis.
2 When the power supply is fully inserted, rotate the power supply handle inward to lock the
power supply in place.
The power supply does not function until the handle is fully closed.
3 Plug the power cable into the power supply, ensuring that the cable passes through the power
cable strain relief loop.
NOTE:
After installing a new power supply, allow several seconds for the system to recognize the power
supply and determine whether it is working properly. The power-on indicator turns green to signify that
the power supply is functioning properly. See Figure 2-4.
