2.2
Installing IST Station Boards In The Equipment Cabinet
1. Normally you should first disconnect the optional battery back-up equipment from the power supply and then
disconnect the AC power cord from the AC outlet; however, when necessary, you can install a station board
in an operating system. If you must do this, connect one end of a standard telephone handset coil cord to the
precharge port on the power supply. During step 5, you will connect the other end of this coil cord to the
precharge jack on the station board.
2. Install your static discharge wrist strap on your bare wrist; adjust it for a snug fit. Be sure that the strap is
touching bare skin and is not isolated by clothing. Connect the wrist strap cord between the wrist strap and an
AC or earth ground
NOTE: With the common equipment in the installed position, the ground lug on the side of the cabinet is an
appropriate grounding point since it should have a heavy ground wire connected between it and a good
earth ground.
3. Loosen the retaining hardware and lift the front panel away from the common equipment cabinet.
4. Each station board is supplied in a static protection bag for safe keeping. When you are ready to install the
circuit board, remove it from its static protection bag.
5. Locate the proper board slot. On DXP Plus systems, the station boards connect to any universal slot; however,
do not install a station board at the right-most board slot in the second (or lower) expansion cabinet. The
system reserves the software timing associated with this slot for internal use.
6. If you are installing the station board in an operating system, connect the free end of the precharge cord that
you installed in step 1 to the precharge jack on the station board.
7. Orient the station board with its top and bottom guides in main cabinet board cage. and press the board firmly
until its board edge connection properly mates with the connector on cabinet’s backplane. If you connected a
handset cord between the pre-charge port on the power supply and the jack on the circuit board, disconnect
the cord after installing the board.
CAUTION
When pressing circuit boards into place, press them only at the extractor lever locations.
If you apply pressure at other locations you may damage the board assembly.
8. Repeat steps 3 and 4 until all circuit boards are installed.
9. Make a final inspection to ensure that all circuit boards are, oriented correctly and mated properly.
10. Install and tighten the supplied screws to secure the circuit boards to the board cage.
11. Each station board includes a ferrite collar. Snap the ferrite collar around the cable station to provide
protection against radio frequency interference.
12. If your installation requires additional DTMF receivers, add receiver cards by following the instructions
included with the card.
13. If the cabinet where you installed the IST station boards does not now include a ring generator assembly,
install a ring generator assembly by following the instructions included with the assembly.
14. Plug the AC line cord into the AC outlet, reconnect any battery back up equipment, and turn on the switch on
the power supply.
15. Replace the front panel on the common equipment cabinet.
