1. Remove the system board mounting tray as follows.
a. Unlock and remove the computer cover.
For instructions, see the Installation and Troubleshooting Guide.
b. To access the system board, release the system-board tray latch at the back
lower corner of the tray (see Figure 1-2) and pull the tray open to the first

tem board.
e. Press and hold the tray release latch as you slide the system board and
mounting tray assembly completely out of the chassis.
