Installing DIMMs
CAUTIONS
Use extreme care when installing a DIMM. Applying too much pressure can
damage the socket. DIMMs are keyed and can be inserted in only one way.
Mixing dissimilar metals may cause later memory failures resulting in data
corruption. Only install DIMMs with gold-plated edge connectors in
gold-plated sockets.
See Chapter 1 for memory size and requirements.
1. Observe the safety and ESD precautions at the beginning of this chapter.
2. Open your server.
3. Holding the DIMM only by its edges, remove it from its antistatic package.
4. Orient the DIMM so that the two notches in the bottom edge of the DIMM align with the keyed
socket.
5. Insert the bottom edge of the DIMM into the socket, and press down firmly on the DIMM until
it seats correctly.
6. Gently push the plastic ejector levers on the socket ends to the upright position.
7. Repeat the steps to install each DIMM.
8. Close the server.
9. Connect all external cables and the power cord to the server.
10. Turn on the monitor and then the server.
