9.2.2 Installing a CPU/Memory Board
1. Attach the ESD wrist strap. Place a grounded ESD mat close to the system.
See Section 2.8, “Antistatic Precautions” on page 2-6 .
2. Install DIMMs on the CPU/Memory board, if required.
See Section 9.3.3, “Installing DIMMs” on page 9-15 .
3. Remove the CPU/Memory board filler board, if fitted.
Caution –
Do not force any board into a slot; it can cause damage to the board and
system. The board should insert and seat smoothly. If it binds, remove the board and
inspect the card cage slot for any obvious obstructions. Also inspect both the board
and the baseplane for bent pins or other damage.
4. Visually inspect the connector(s) for damage.
5. Grasp the green side panels and gently insert the CPU/Memory board into the
grooves until the antigravity clutch is engaged (
FIGURE 9-5
).
The antigravity clutch holds the board in position so that it can be released without
the board sliding down into the system.
