To install a DIMM, complete the following steps.
1. Before you begin, read "Safety" on page v and "Installation guidelines" on page 44.
2. Turn off the server (see "Turning off the server" on page 40) and all attached peripheral devices.
Disconnect all power cords; then, disconnect all external cables from the server.
3. Remove the compute book from the server (see "Removing a compute book" on page 291).
4. Remove the compute book cover (left or right cover - depending on the DIMM connector in which you
are installing the DIMM). Press down on both blue touch points on the cover and slide the cover toward
the rear of the expansion module.
Attention: Remove only one cover (on one side) at a time to protect the compute book components on
the other side of the compute book from being damaged.
