Attention: Static electricity that is released to internal server components when the server is powered-on might cause the server to stop, which could result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when working inside the server with the power on.

To install a DIMM, complete the following steps:

1.Read the safety information that begins on page v and “Installation guidelines” on page 7.

2.Turn off the server and peripheral devices, and disconnect the power cords and all external cables.

3.Remove the side cover (see “Removing the side cover” on page 10).
