Important: To ensure proper cooling during normal server operation, both of the power supply bays
must be occupied. This means that each bay must have a power supply installed; or one has a power
supply installed and the other has a power supply filler installed.
2. If you are instructed to return the old hot-swap power supply, follow all packaging instructions and use

About this task
The following describes the information that you must consider when installing a power supply unit.

Attention:
• Read “Installation Guidelines” on page 27 to ensure that you work safely.
• Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-
sensitive components in their static-protective packages until installation, and handling these devices with
an electrostatic-discharge wrist strap or other grounding system.
Procedure
Step 1. Touch the static-protective package that contains the hot-swap power supply to any unpainted
surface on the outside of the server. Then, take the hot-swap power supply out of the package and
place it on a static-protective surface.
Step 2. If there is a power-supply filler installed, remove it.
