HPE ATX 550 W power supply option

This section provides instructions for installing an ATX 550 W power supply option.

WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system components to cool before touching them.

CAUTION: To prevent damage to electrical components, take the appropriate anti-static precautions before beginning any installation, removal, or replacement procedure. Improper grounding can cause electrostatic discharge.

For more information about product features, specifications, options, configurations, and compatibility, see the product QuickSpecs on the Hewlett Packard Enterprise website.

To install the component:

1. Power down the server.
2. Remove all power:
   1. Disconnect each power cord from the power source.
   2. Disconnect each power cord from the server.
3. Place the server on a sturdy, level surface.
4. Remove the access panel.
5. If installed, remove the PCI air baffle.
6. Remove the system air baffle.
7. Disconnect all power supply cables from the system board, drive cages, and devices.
8. Remove the existing power supply.

   

9. Install the ATX 550 W power supply.

   

10. Connect the 550 W ATX power cables and then route the cables underneath the metal tabs:
    • 4 LFF non-hot-plug configuration
      • Optical drive power cable to optical drive
      • 8-pin drive power cable to the non-hot-plug drive power connector
      • 6-pin power cable connecting to GPU, if installed
      • 4-pin power cable connecting to system board
      • 24-pin power cable connecting to system board

        

    • 4 LFF and 8 SFF hot-plug configuration
      • Optical drive power cable to optical drive
      • 8-pin drive power cable to the hot-plug drive backplanes
      • 6-pin power cable connecting to GPU, if installed
      • 4-pin power cable connecting to system board
      • 24-pin power cable connecting to system board

        4 LFF hot-plug configuration

        

        8 SFF hot-plug configuration

        

        CAUTION: To prevent improper cooling and thermal damage, do not operate the server unless all bays are populated with either a component or a blank.

11. Install the system air baffle.
12. If removed, install the PCI air baffle.
