Installing the power interposer for redundant power supply card assembly

Use this information to install the power interposer.

The Power Interposer for Redundant Power Supply option enables redundant power support when no microprocessor and memory expansion tray is installed. To install the optional power interposer card assembly, complete the following steps:

1. Read the safety information and installation guidelines, see Safety and Installation guidelines.
2. Turn off the server (see Turning off the server) and all attached peripheral devices. Disconnect all power cords; then, disconnect all external cables from the server.
3. Remove the top cover (see Removing the server top cover).
4. Align the power connectors on the power interposer card so that they are aligned with the power interposer card connectors on the system board; then, press down on the power interposer card until it is firmly seated in the connectors on the system board.

   

5. Install the power supply that comes with the power interposer card, (see Installing a 1400-watt or 900-watt hot-swap power supply) or (Installing a 750-watt -48 volt to -60 volt dc power supply).

If you have other devices to install or remove, do so now. Otherwise, go to Completing the installation.
