Procedure
To install line cards and reinstall the multislot filler plate:
8820-A2-GN20-80
1. Install a line card into the slot. It is recommended that you install BAC cards in
contiguous slots to optimize the cabling. Covering empty slots is required to
maintain EMI shielding and proper cooling.
2. Verify that the LEDs show proper operation (see
page 2-27).
3. Tighten the screws to fasten the card to the chassis. It is recommended that
slight pressure be applied to the faceplate toward the left as you are tightening
the card screws. This will insure a good board-to-board EMI seal.
4. Repeat Step 1 through
5. Slip the right side of the multislot filler plate (side without the EMI gaskets) into
the receptacle as shown below.
6. Ensure that a good EMI seal is made with the EMI gaskets on the left side of
the multislot filler plate by applying slight pressure to the left.
7. Replace the screws in the multislot filler plate to fasten it to the chassis.
