   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.
2. Slightly slide power supply 2 out from the power supply bay (see ).
3. 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.
4. Rotate the handle all the way down. This connects and fix the expansion tray to the system board.

7. If you plan to install memory modules, do it now (see Install a memory module).
8. Install the expansion tray air baffle.
   Attention

   1. For the optimal performance, make sure both PHMs and corresponding memory modules 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.
