Install the M.2 backplane assembly

Use this information to install the M.2 backplane assembly.

Procedure

1. If there is an I/O expansion adapter installed in I/O expansion connector 2, remove it from the compute node. See System-board layout and Remove an I/O expansion adapter.
2. Connect the M.2 backplane assembly cables to the M.2 backplane.
   1. Tilt the connector at an angle of 20 degrees or lower, and insert it until its bottom surface reaches the ramp.
   2. Press the connector down flat.
   3. Tighten the screw on the signal cable.
   4. Connect the power cable.

3. Install the M.2 backplane assembly.
   1. Place the M.2 backplane assembly on air baffle and slide it into the clip on the edge of the air baffle.
   2. Tighten the screw to secure the M.2 backplane assembly to the air baffle.
