5.1.2 Installing the New QuickConnect™ Module
1) Make sure the power switch on the base unit is off. Leave the
power cord plugged into a grounded outlet to keep the unit
grounded.
2) Hold the module with the faceplate toward you and align the
module with the guide slots in the rear panel of the base unit.
3) While keeping the module's faceplate parallel with the base unit
rear panel, slide the module straight in–so that the card edge
contacts line up with the socket inside the chassis. Figure 4
(below) shows how a Quick Connect Module plugs into the rear
of the base unit.
Figure 4. Installation of Model IM 1/I Plug-in Serial Interface Module
NOTE: The card edge connector should meet the socket when
it is almost all the way into the chassis. If you encounter a lot of
resistance, remove the module and repeat steps 2 & 3.
4) With the card edge contacts aligned with the socket, firmly seat
the module by using your thumbs to apply pressure directly to
the right and left edges of the module faceplate. Applying
moderate and even pressure should be sufficient to seat the
module. You should hear it "click" into place.
5) To secure the module in place, push the thumbscrews into the
chassis and turn the screws clockwise to tighten.
