Installing DIMMs

DIMMs must be installed in pairs of the same type and speed. For you to use the
memory mirroring feature, all the DIMMs that are installed in the server must be of
the same type and speed, and the operating system must support the feature. The
following instructions are for installing one pair of DIMMs. To install DIMM pairs on
more than one memory card, repeat step 4 on page 40 though step 12 on page 41
for each memory card.
Installing a DIMM
To install a DIMM, complete the following steps:
a. Touch the static-protective package that contains the memory card to any
unpainted surface on the outside of the server; then, remove the memory
card from the package.
b. Place the memory card on a flat, static-protected surface with the DIMM
connectors facing up.
c. Install DIMMs in the memory card (see "Installing DIMMs").
Attention: When moving the memory card, do not allow it to touch any
components or structures inside the server.
a. Make sure that the retention levers on the edge of the memory card are fully
open.
b. Lift the memory card out of the server.

card so that the connector aligns with the connector on the microprocessor
board.

c. Press the memory card into the connector and close the small retention
lever.
