Installing a PVDM
To install a PVDM, follow these steps:
Note Install PVDMs beginning with the PVDM 0 connector.
Step 1 Locate the PVDM connector on the motherboard. See Figure 51 and Figure 52 for PVDM connector
locations.
Step 2 Orient the PVDM so that the polarization notch lines up with the key on the connector. See Figure 64.
Step 3 Hold the PVDM at an angle and insert it carefully into the PVDM connector. Tilt the PVDM up to the
vertical position so that the clips snap into place at both ends. See Figure 65.
