Step 1) Mount Cards in Card Cage
The CX452 Crossover unit has 5 card slots. When installing
a card into the CX452 slide it in using the card guides for
alignment. Use the #4-40 screw on the top to secure the card in
place. Unused card slots can be covered up with blank covers.
RJ45 jacks on the front of the card provide the connection
for each camera run. To meet TIA/EIA standards your camera runs
should be terminated in a patch panel. Using standard patch cables
connect the camera ports to the patch panel. The camera runs
should be wired for T568B standard.
Step 2) Connect Horizontal Runs
Before connecting each camera run to a card verify that it is
properly wired using the CAMERA PORT chart below. The
maximum output of any camera port is 21 watts. The maximum
current output for all 4 camera ports on a card is 80 watts.
