Installing Memory

IMPORTANT: You must pull the ac power plugs on the server every time you modify the DIMMs. If you do not pull the ac power plugs, the system does not display the correct DIMM information.

To install memory, follow these steps:

1.Power off the server and disconnect the power cables. See “Powering Off the Server” (page 95).

2.If rack installed, slide the server out from the rack until it stops. See “Extending the Server from the Rack” (page 180).

3.Unlatch the cover release lever on the top cover and remove the memory carrier assembly cover. See “Removing the Memory Carrier Assembly Cover” (page 183).

NOTE: You do not need to fully remove the top cover to service this component; however, the top cover release lever must be open.

4.Remove the memory carrier assembly. See “Removing the Memory Carrier Assembly” (page 204).
