CPU/Memory board.
The CPU/Memory board slots are marked on the side of the chassis.
2. If a CPU/Memory board connector dust cover or connector protector is installed
on the centerplane and CPU/Memory board connectors, remove it.
Caution – Do not attempt to install the CPU/Memory board before removing the
dust cover. Doing so could damage the CPU/Memory board or the centerplane.
