1. Unpack the PMC module from the shipping carton in a suitable work area. If the ship-
ping carton appears to be damaged, request that an agent of the shipper or carrier be
present during packing and inspection.
2. Find the packing list. Verify that all items on the list are present.
3. Save the packing material for storing or reshipping the card.
Before installing the PMC module on the SCP/DCP-122, ensure that you complete all
pre-installation tasks described in the associated PMC user documentation.

ODULE
ON
THE
SCP/DCP-122
Install your PMC module on the SCP/DCP-122 using the appropriate mounting kit available
from Dy 4 Systems. This kit contains all the screws and additional hardware you need to
ensure that the PMC module is firmly installed on your SCP/DCP-122.
Installing a PMC
Module on a
DCP-122
Figure 3.1 on page 3-3 shows a PMC module in position over a DCP-122.
Thermal gaskets in the PMC mounting kit ensure a good thermal connection between the
frame of the PMC module and the carrier card. These gaskets are white strips of thermal
material with holes to match the holes in the primary and secondary thermal interfaces (five
holes on the primary interface, and three holes on the secondary). Remove the backing from
the thermal gaskets and affix them to the thermal frame of your PMC module.
Your mounting kit may include thermal pads of a thicker material to conduct heat away from
some components through the thermal frame on the carrier card. Remove the backing from
the pads and affix them to the appropriate components.
The kits also contain at least eighteen 2 mm screws with washers and two 2.5 mm screws
to fasten the PMC module to the frame. The two 2.5 mm screws fasten the SCP/DCP-122 to
the two integral standoffs on the carrier card frame (as indicated in Figure 3.1).
Alternatively, if the carrier card frame does not include integral standoffs, use the individual
standoffs included in the mounting kit. The 2 mm screws and washers affix the card by the
primary and secondary thermal interfaces.
Note
If the PMC module you are installing on the DCP-122 is not a Dy 4 product, make sure the
module has a compatible thermal frame.
Note
Torque the PMC mounting screws at exactly 4 lb-in, as indicated on the basecard generic
drawing supplied on your Dy 4 basecard Technical Documentation CD-ROM.
Dy 4 Systems recommends using a thread locking compound, such as Loctite 222MS
Threadlocker (Dy 4 part number 163220) to prevent the screws from becoming loose.
