Guidelines” on page 51).
2. Touch the static-protective package that contains the component to any unpainted metal surface on the
server; then, remove it from the package and place it on a static-protective surface.
3. If the server is in a rack, adjust the cable management arm (CMA) to gain access to the power supply
bay.

installed, turn off the server and peripheral devices, and disconnect the power cords and all external
cables; then, remove the installed power supply unit (see “Remove a hot-swap power supply unit” on
page 93).
Important: Do not mix power supplies with different wattages in the same server.
