CEM3 Rack Retrofit Manual
8:
Install the 3-pin beacon connector. The wires travel out of the bottom of the
CEM3.
9:
Connect the Cat 5 Ethernet cable to the RJ-45 connector on the CEM3 backplane.
(Not shown in the drawing below for clarity.).
Finish Installing the Backplane
10:
Push the backplane completely into place in the rack. Be careful not to disrupt the power and
data connections you just made. Make sure none of the wiring becomes stressed or pinched.
11:
Insert the backplane tabs in the side of the enclosure.
12:
With the tabs fully inserted in the sides of the
enclosure, pull the backplane towards the
front of the rack to line up the screw holes in
the upper side corners to line up.
13:
Install one screw with a sleeve in each side
upper-corner of the backplane.
Transfer Panic Wiring (if present)
If the enclosure had a panic connection in the previous backplane configuration, terminate the panic
connections to the new backplane.
1:
Locate the wire pair for the panic connection.
2:
Cut and strip 3/16” (5 mm) of insulation from the wires.
3:
Connect the panic wires to the “PANIC SEND” and “PANIC RETURN” terminals.
4:
Move the panic configuration switch (to the right of the terminals) to the appropriate position:
• NO for Normally Open contact types
• NC for Normally Closed contact types
Note:
You cannot use the old screws without the additional shoulder-sleeve as they will
block the CEM3 from being fully inserted.
