NSTALLATION
UTM installation consists of:
inserting the DTK41 or CEY5 I/O distribution board into the backplane slot
inserting the module in the corresponding shelf slot
cabling console and data ports
Note: To avoid damage to electronic components from ESD (Electro Static Discharge) always
wear an ESD wrist strap. To prevent damage to module circuitry, always insert the I/O board
before inserting its corresponding module. Never remove the I/O board before removing the
module.

NSERTING THE
I/O B
OARD
The I/O board plugs into the backplane at the rear of the shelf. It is held in place by shrouds on
the backplane pinfield and secured with two screws. Insert the I/O board before inserting its
corresponding UTM.
Align the I/O board backplane connector with the backplane pinfield and align the screw slots
with the screw holes.
Slip the backplane connector onto the pins. The board should seat easily. If seating is
difficult, the board may be canted or some pins may be bent.
Insert the screws, and tighten them securely.
Removing the I/O Board
Remove the I/O board only for relocation, replacement, or board type confirmation.
Note: The Module in the slot corresponding to the I/O board must be removed first.
Disconnect all cabling to I/O board ports, labeling the cable ends if appropriate.
Remove the screws holding the I/O board in place.
Carefully rock the board as you pull it out.
Inserting the UTM
Note: The I/O board for the module must be installed in its corresponding slot on the backplane at
the rear of the shelf first.
Set the mode switch on the module faceplate to Disab.
With the module latch extended, carefully push the module all the way into the slot. The
backplane pins slip into the module receptacle.
Close the latch to lock the module into position.
Move the mode switch on the module faceplate to Enabl.
Removing the UTM
Note: You can remove and replace a UTM in an operating node without damaging the module
itself, or without disrupting calls on other modules. Only the calls on the UTM being removed are
disrupted. Remember that the I/O board for the module must still be in its corresponding slot on
the backplane at the rear of the shelf.
If the mode switch is in the Enabl position, move it to Disab.
Open the latch on the module faceplate.
Pull the module straight out of the slot.
