Chapter 4: Installation Procedures
Cover Unused Card Slots
Any empty slots in the radio and utility shelves should be covered with filler
panels. The filler panels ensure airflow to the other cards and protect the cards
from dust and electromagnetic interference.
 To cover the unused slots with filler panels
1 Remove the filler panel from its protective bag.
2 Set the two ejector handles on the filler panel in the open position by turning the
handles away from the center of the front panel.
In the open position, the ejector handles are at an approximately 45° angle from
the front panel.
3 Ensure that the mounting screws are withdrawn enough to allow for the insertion
of the filler panel.
Single-slot filler panels have two mounting screws, one located under each ejector
handle. Double-slot filler panels have four mounting screws, one located under
each ejector handle and one located beside each ejector handle.
4 Orient the filler panel so that the guide pins are on the right-hand side of the
ejector handles.
5 Slide the filler panel into the slot. The guide pins should slide into the round holes
located at the top and the bottom of each slot on the right-hand side. Apply
sufficient pressure to fully mate the filler panel with the shelf.
6 Lock the filler panel in the slot by turning the handles towards the center of the
front panel.
In the lock position, the ejector handles are at a 90° angle from the front panel.
7 Secure the filler panel in the slot by installing the 2.5-mm mounting screws.
Torque each screw to 4 inch-pounds.
8 Ensure that the filler panel is secure by grasping both ejector handles and pulling
lightly. The filler panel should not move.
If the filler panel does move, ensure that the mounting screws are attached to the
shelf frame. If necessary, remove the panel and repeat this procedure.
9 Repeat steps 1 to 8 until all the empty slots are covered with filler panels.
