7.9.3.2 BPC (BIC) or BPC+SPAM (AIC)

Before replacing any card (board) in the BIC or AIC, power down RFN equipment in the

following order using circuit breakers on the PDU:

• BIC

• AIC

• RBS 1 (power down RBS 2 and RBS 3 if they are present)

• RF Shelves 1, 2 and 3

2 Always use a static grounding wrist strap before handling any board—do not attach the wrist

strap to any painted surface on the chassis unit.

3 Facing the chassis unit, remove the BPC that is to be replaced, or the blank faceplate,

following these guidelines:

• Loosen the blue knurled knobs on both sides of the board.

• Pull firmly on the tabs located on the bottom of the BPC you are replacing.

• Gently slide the BPC straight out and away from the chassis unit so as not to damage

any components contained on the board.

4 Remove the BPC from its antistatic packaging and insert it into the chassis unit as shown in

the following illustration, and follow these guidelines:

• Do not jam the board in any way while inserting it.

• Do not mount the board in any orientation other than that specified in the diagram.

• Insert the board straight into the chassis unit so as not to damage any components

contained on the board.

• Press firmly to seat the board into the connectors within the chassis unit.

• Tighten the blue knurled knobs on each end of the board finger tight only—do not use a

screwdriver to tighten the screws and do not over tighten.
