Release latch
To install a hot-swap power supply, do the following:
1. Read the safety information Safety information.
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.
5. Connect one end of the power cord for the new power supply into the connector on the back of the
power supply; then, connect the other end of the power cord to a properly grounded electrical outlet.
Note: If the server has been turned off, you must wait approximately 3 minutes after you connect the
server power cord to an electrical outlet before the power-control button becomes active.
6. Make sure that the ac power LED on the top of the power supply is lit, indicating that the power supply
is operating correctly. If the server is turned on, make sure that the dc power LED on the top of the
power supply is lit also.
