3. Remove the cover plate on the left end of the front of the station

by removing the two screws from the front of the plate, then

removing the four Phillips screws from the side and bottom

edges of the plate.

4. Pull out the old Control Module by gripping behind its DB-9,

RJ-11, and RJ-45 connectors, distributing pressure equally

among the connectors.

5. Insert the new module. Make sure it is in the cardguides; push it

ﬁrmly into the chassis until it seats into the card-edge

connectors on the backplane. (Do not slam the board against the

backplane or push any harder than necessary to seat the

connectors.)

6. If desired, power up the station while it is still out of the case to

make sure the module is securely in place. If the LEDs do not

light, are dim, or ﬂash rapidly, one or more modules are not

seated properly. Unplug the station before continuing to the

next step.

7. Reassemble the station by reversing Steps 2 and 3.
