Chapter 2 Setting Up the System 39
How to Install a Power Supply
Before You Begin
If you are installing a redundant power supply, it is not necessary to shut down and
power off the system. For more information, see:
■
“About Power Supplies” on page 73
■
“About Hot-Pluggable and Hot-Swappable Components” on page 144
Note –
After removing a power supply during a hot-plug operation, wait for an
acknowledgement message on the system console before installing a new supply;
otherwise, the environmental monitoring software will not recognize the new device
and false error conditions will result.
What to Do
1. If you are upgrading your system with an additional power supply, remove the
filler panel covering the empty power supply bay.
Remove the two Phillips screws that secure the panel to the chassis and slide the
panel out of the bay.
2. Slide the new power supply into the empty bay until the power supply connectors
start to engage the connectors on the power distribution board.
3. Push firmly on the power supply handle to engage the power supply connectors.
Caution – If you are hot-plugging a redundant supply, take care to avoid jarring or
shocking the system. Also, do not engage and disengage the supply in rapid
succession. Rapid seating and unseating of a power supply will result in false error
conditions.
