Hot-swap power supply

Release latch

To install a hot-swap power supply, do the following:

1.Read the safety information Chapter 2, “Safety information,” on page 5.

Attention: Static electricity that is released to internal server components when the server is powered on might cause the server to halt, which might result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when you work inside the server with the power on.

2.Touch the static-protective package that contains the power supply to any unpainted metal surface on the server; then, remove the power supply from the package.

3.Remove the power-supply filler panel from the power bay, if one is installed.

4.Place the power supply into the power-supply cage and push it in until it locks into place.

Note: If only one hot-swap power supply is installed in the server, a power-supply filler must be installed in the empty power bay.
