Install the processor and memory expansion tray

Use this procedure to install the processor and memory expansion tray.

To install the processor and memory expansion tray, complete the following steps:

  1. If the power interposer and system board air baffle are installed, remove them (see Remove the system board air baffle and the power interposer).
  2. Install an expansion tray air baffle on the system board. Make sure it is properly installed before installing the processor and memory expansion tray.
    Figure 1. Expansion tray air baffle installation

    Attention
    Air baffle is required for airflow that creates proper cooling. Make sure proper air baffles for system configuration is installed before the power is turned on.
  3. Slightly slide power supply 2 out from the power supply bay (see ).
  4. Grip on the blue touch point on the handle of the expansion tray, and lift it up; then, lower the tray vertically into the server with nailheads aligned to the slots on both sides.
  5. Rotate the handle all the way down. This connects and fix the expansion tray to the system board.

  6. Slide the power supply 2 back into the chassis.
  7. Install DIMMs (see Install a memory module), PHMs (see Install a processor and heat sink), and the expansion tray air baffle on the expansion tray.

    Attention
    1. For the optimal performance, make sure both PHMs and corresponding DIMMs are installed to the processor and memory expansion tray.
    2. Air baffle is required for airflow that creates proper cooling. Make sure proper air baffles for system configuration is installed before the power is turned on.
