Slide the card out of the rack slowly with equal pressure on both the top and bottom of the card. NOTE: Observe all ESD proper precautions when handling any part of the Front End Processor. • TD Boards 0-7, EQ Board, BMP Board, EBM/EBM2 Board • XDIF and RF Amp/RF Amp2 a.) Remove the three screws that fasten the XDIF board to the front of the card rack chassis. b.) Carefully eject and partially remove the XDIF and RF Amp boards simultaneously . Remove the boards just enough in order to grab both sides of the Top Plane board. c.) Hold the XDIF and RF Amp boards. Carefully grab each SIDE of the Top Plane Board. Gently rock the Top Plane board side to side while pulling it off of its connectors. NOTE: Rocking the Top Plane board top to bottom will afford a greater opportunity to bend pins during its extraction. Only rock the board side-to-side while removing it. d.) Once the Top Plane Board is removed, either the XDIF or RF Amp can be removed from the card rack.Figure 8-142 Side View of System with Card Cage Open CAUTIONThe following boards require special attention when removing them from the card rack.

For the old supplies, remove the one screw at the bottom of the Power Supply Board. b.) If necessary, unscrew the two thumb screws attaching a cover plate over the PCI cable as it enters the card rack chassis. c.) Partially remove the SCB and Power Supply boards simultaneously. Remove them just enough to gain access to the PCI cable from the Back End Processor that passes through the Power Supply board and attaches to the SCB. d.) Disconnect the PCI cable from the SCB and pull it through the hole in the Power Supply board. e.) If you are removing just the SCB, completely slide it out of the card rack. f.) If you are removing the Power Supply board, pull the PCI cable out of the card rack chassis so it will not interfere with the Power Supply board. g.) Pull the Power Supply board out of the rack to expose the black/white/green AC input wires. h.) Disconnect these wires from the Power Supply board and slide the board out of the card rack. 8-34-5 Front End Board Installation Procedure • The TD Boards 0-7, EQ Board, BMP Board and EBM/EBM2 a.) Installation is accomplished by sliding the top and bottom edges of the board into the guide slots with firm even pressure to securely seat the board into the motherboard and secure it with the ejectors. • XDIF, RF Amp/RF Amp2 and Top Plane a.) When inserting the XDIF board back into the card rack, ensure that the RF shield is behind the card rails to avoid binding. b.) Slide the XDIF in and secure it with the three screws. c.) Slide in the RF Amp. d.) Install the Top Plane board by first aligning the pins and then pushing straight in to seat the board. • SCB and Power Supply (FEPS, FEPS2, FEPS2.1, FEPS3) a.) The SCB and Power Supply Boards should be started simultaneously but not pushed in all the way. b.) Reconnect the black/white/green AC input wires on the Power Supply board. c.) Thread the PCI cable through the chassis and Power Supply board and connect it to the SCB. d.) Simultaneously seat the SCB and Power Supply boards into motherboard. e.) If removed, replace the RF shield over the PCI Cable chassis hole. f.) Since there is no ejector at the bottom of the Power Supply board, be sure to push firmly on the bottom to completely seat the card. Secure the bottom of the Power Supply board with the screw previously removed. WARNINGWARNINGEnsure that the system is turned off and unplugged. Wait at least 20 seconds for the charge on the FEPS capacitors to bleed off before handling the power supply board.
