Working with memory modules Before you begin: Read "Electrical safety" on page 70 and "Handling static-sensitive devices" on page 71. Read the documentation that comes with the option. Read "Accessing the system board" on page 78. Notes: 1. When you are removing a memory module, be careful not to push too hard on the retaining clips because the memory module might abruptly eject from the connector. 2. Each memory connector contains two keys (dividers), which are used to assure that a memory-module can be installed only in the correct position. 3. A retaining clip at each end of the connector locks the memory module into place. 4. For information about memory configuration, see Table 1 and Table 2 on page 98. To install a DIMM: 1. Remove the server side cover (see "Disconnecting cables and removing the side cover" on page 74). 2. Locate the memory connectors on the system board. See the illustration at the beginning of this section. 3. Be sure that the retaining clips are in the open position, as shown in the following right-hand illustration. If the retaining clips are perpendicular to the connector, push outward on them until they click open. Chapter 4. Installing options 99
