Figure 25. 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 processor 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 option:
• If there are DIMMs to install, install them. See
“Install a DIMM” on page 37 for instructions.
Install the interposer card
Use this information to install a interposer card option.
Before you install a interposer card, complete the following steps:
1. Read
“Installation Guidelines” on page 28 to ensure that you work safely.
2. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the
bezel pointing toward you.
3. Remove the compute node cover (see
“Remove the compute node cover” on page 32 for instructions).
To install the interposer card, complete the following steps:
