Install A Memory Module - Lenovo ThinkSystem SR550 Setup Manual

Figure 31. Installing a PHM
a. Align the triangular marks and guide pins on the processor socket with the PHM; then, insert
the PHM into the processor socket.
Attention: To prevent damage to components, make sure that you follow the indicated
tightening sequence.
b. Fully tighten the Torx T30 captive fasteners in the installation sequence shown on the heat-sink
label. Tighten the screws until they stop; then, visually inspect to make sure that there is no
gap between the screw shoulder beneath the heat sink and the microprocessor socket. (For
reference, the torque required for the nuts to fully tighten is 1.4 — 1.6 newton-meters, 12 — 14
inch-pounds).
After installing the PHM:
1. If you are installing the second PHM, remove the fan filler and install the new system fan that comes with
the processor option kit. See "Install a system fan" on page 66.
Note: An Intel Xeon SP Gen 2 processor does not come with a system fan. If you are installing an Intel
Xeon SP Gen 2 processor, ensure that you have ordered the ThinkSystem SR550 FAN Option Kit and
install it.
2. If there are memory modules to install, install them. See "Install a memory module" on page 55.
