UMI installation consists of:
• inserting the DTK41 or CEY5 distribution board in the backplane slot
• inserting the module in the corresponding shelf slot
• cabling console and data ports
When installing a UMI:
• Ensure protection from electromagnetic interference (EMI). Wear an electrostatic discharge
(ESD) wrist strap to prevent equipment damage.
• 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.
3.1 INSERTING THE I/O BOARD
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 UMI.
• 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.
3.2 REMOVING THE I/O BOARD
Remove the I/O board only for relocation, replacement, or board type confirmation.
Requirement: 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.
3.3 INSERTING THE UMI MODULE
Requirement: 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.
3.4 REMOVING THE UMI MODULE
You can remove and replace a UMI in an operating node without damaging the module itself, or
without disrupting calls on other modules. Only the calls on the UMI being removed are disrupted.
Requirement: 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.
