Removing and Installing Station Boards
1. Normally you should disconnect the AC power cord from the AC outlet and disconnect the optional battery
back-up assembly from the power supply; however, when necessary, you can remove or install a line board
in an operating system. If you must do this, connect one end of a standard telephone handset coil cord to the
pre-charge port on the power supply. (On FXT systems, the pre-charge cord is pre-wired to the power supply
and hangs between it and the circuit board cage.) During step 5, you will connect the other end of this coil
cord to the precharge jack on the line board.
2. Make sure you are wearing a static discharge wrist strap. Be sure the strap is touching bare skin and is not
isolated by clothing. Connect the wrist strap to 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. Each new station board is supplied in a static protection bag. Do not remove a board from it’s static
protection bag until you are ready to install it. Conversely, when you remove a station board from the
cabinet, immediately place it in a static protection bag.
4. Locate the proper board slot—on Impact FX systems the station boards connect to any universal slot.
5. If you are removing or installing the station board in an operating system, connect the free end of the
pre-charge cord to the pre-charge jack on the station board.
6. If you are removing station boards from the cabinet, remove the retaining hardware, pull the boards toward
you until the board edge connectors separate from the cabinet’s backplane connection, and slide the boards
free of the cabinet.
7. To install station boards, orient them with the left and right guides in cabinet board cage and press the boards
firmly until the board edge connectors properly mate with the connection on the cabinet’s backplane.
8. Make a final inspection to ensure that all station boards are oriented correctly and mated properly.
9. Install and tighten the supplied screws to secure the installed boards to the board cage.
10. Each station board includes a ferrite collar. Snap the ferrite collar around the cable to provide protection
against radio frequency interference.
