Attention: During normal operation, each power-supply bay must have either a
power supply or power-supply filler installed for proper cooling.
To install a hot-swap ac power supply, complete the following steps:
Procedure
1. Read the Safety information and "Installation guidelines" on page 94.
2. Touch the static-protective package that contains the hot-swap power supply to
any unpainted metal surface on the server; then, remove the power supply
from the package and place it on a static-protective surface.
3. If you are adding a power supply to the server, attach the redundant power
information label that comes with this option on the server cover near the
power supplies.

4. Slide the power supply into the bay until the retention latch clicks into place.
Attention: Do not install the different power rating or wattage of power
supplies, high-efficiency and non-high-efficiency power supplies in the server.
5. Connect the power cord for the new power supply to the power-cord connector
on the power supply.
