Figure 3: Installing a PMC Module
To install a PMC module:
1. Confirm that the device is powered off.
2. Remove the processor module by unscrewing the retaining screws and pushing the
extractors outward with the latching buttons depressed.
3. A shield may have been installed in the PMC slot of the processor’s front panel. Remove
this shield by gently pushing it out from behind the panel.
4. The PMC module has four screws. Two of the screws are secured to standoffs, and
two are attached to the front assembly of the PMC module. Remove the two screws
secured to the standoff, leaving the standoff attached to the PMC module. Remove
the two screws on the front assembly located on the side with the standoffs. The
front assembly should remain attached to the PMC hardware. Keep the screws for
reattachment.
5. Align the PMC module with the printed circuit board connectors toward the processor
board and with the fiber connectors inserted through the processor’s front panel. Align
the alignment post on the processor module with the PMC module’s alignment hole.
6. Gently press the PMC module into the processor module.
