Important: Compute trays must be inserted in the chassis with the processors and memory visible from the
top.
Step 1. Align the compute tray with its opening in the front of the chassis and insert.
Step 2. Fully open the compute tray release levers and push the compute tray into the chassis until it stops.
Step 3. Rotate the compute tray release levers until they lock, fully closed.
If you are done performing installation or maintenance procedures at the front of the chassis, install the front
cover. See “Install the front cover” on page 322.
System board replacement
System boards are in the upper or lower compute tray that is accessed from the front of the server.
Important: Before you return the system board, make sure that you install the CPU socket covers from the
