HP ProLiant ML350 G5 Server - Installing a Processor

Processor option

The server supports single- and dual-processor operation. With two processors installed, the server supports boot functions through the processor installed in processor socket 1. However, if processor 1 fails, the system automatically boots from processor 2 and provides a processor failure message.

The server uses an embedded PPM 1 as a DC-to-DC converter to provide the proper power to processor 1.

CAUTION: To prevent possible server malfunction, do not mix processors of different speeds or cache sizes. Refer to the label on the processor heatsink for a description of the processor.
CAUTION: Processor socket 1 must be populated at all times or the server does not function.
CAUTION: Removal of the processor or heatsink renders the thermal layer between the processor and heatsink useless. A new heatsink must be ordered and installed before reinstalling the processor.

To install the component:

  1. Power down the server.
  2. Do one of the following:
    • Open or remove the tower bezel, as needed.
    • Extend the server from the rack.
  3. Remove the access panel.
  4. Open the processor retaining latch and the processor socket retaining bracket.
  5. Remove the processor socket protective cover.
    CAUTION: Be sure the processor remains inside the processor installation tool.
  6. If the processor has separated from the installation tool, carefully re-insert the processor in the tool.
  7. Align the processor installation tool with the socket and install the processor.
  8. Press down firmly until the processor installation tool clicks and separates from the processor, and then remove the processor installation tool.
  9. Close the processor socket retaining bracket and the processor retaining latch.
  10. Open the heatsink locking levers.
  11. Remove the heatsink protective cover.
  12. Install the heatsink fan. The heatsink fan points to the rear of the server.
  13. Close the heatsink locking levers.
  14. Connect the heatsink fan cable to the connector on the system board.
  15. Install the PPM.
  16. Close the latches.
    NOTE: The appearance of compatible PPMs may vary.
  17. Install the access panel.
  18. Do one of the following:
    • Close or install the tower bezel, as needed.
    • Slide the server back into the rack.
  19. Power up the server.
