5 HARDWARE INSTALLATION

Remove power to the shelf by turning off the power supply or unplugging the power transformer connected to the chassis.

If proceeding with an upgrade of a current installation it may be necessary to remove any cable wrap, clamps or cord form any existing cable brackets to allow room for installation of the conversion boards. Be careful not to damage cables or connectors in the process.

Working at the back of the equipment bay, install an FFM-01 or FFM-02 conversion board, as appropriate, into a slot at the right-most vacant position of the chassis. Conversion boards can only be installed in positions 1 through 16. Proceed as follows. While facing the back of the chassis, hold the conversion board in a vertical position with the 34-pin connectors towards yourself and the 25-pin connectors away for you. Place the three 25-pin connectors into the three 25-pin mating connectors on the chassis and press firmly into place. Tighten the two mounting screws per connector to assure a good connection.

The FF-01 or FF-02 conversion board is meant to convert the 17th position of the RDC-01/PSC-

01or RDC-02/PSC-02 PatchSwitch chassis to be used with the PSM-18 or PSM-19 interface modules. In addition, this module can also convert position 1 to 16 of the RDC-01/PSC-01 chassis to be used as interface module positions. If position 1-16 of a RDC-02/PSC-02 chassis must be converted to interface module positions, then the FF-02 must be used.

Bring the end of the DCE cable in from the side of the equipment rack and connect it to the bottom connector on the conversion board. Form the cable neatly away from the board along an equipment rack cable bracket towards the equipment rack upright. Be sure that the conversion board does not have any side pressure from the cable in any direction. Using cable straps or appropriate cord, fasten the cable to the cable bracket as applicable.

Bring the end of the “B” DTE cable in from the other side of the equipment rack and connect it to the middle connector on the conversion board. Form the cable neatly away from the connector sub-board along an equipment rack cable bracket towards the equipment rack upright. Be sure that the conversion board does not have any side pressure from the cable in any direction. Using cable straps or appropriate cord fasten the cable to the cable bracket. Bring the end of the “A” DTE cable in from the the side of the equipment rack and connect it to the top connector on the conversion board. Form the cable neatly away from the conversion board along an equipment rack cable support bracket towards the equipment rack upright. Install additional conversion boards using the directions above. Work from the right side of the chassis towards the left (as seen from the rear). This gives room to the left in which to work and makes for a much neater installation.

Carefully install the PatchSwitch V.35 module into the chassis making sure that the 96-pin DIN connector on the front of the unit engages the connector in the chassis. Tighten the hold-down screws on the front of the module

Plug the power transformer removed earlier back into its socket or turn on the power supply to re-establish power for the units.
