2. Installation
Procedure
To install DSL cards and reinstall the multislot filler plate:
2-20
1. Install a DSL card into the slot. It is recommended that you install GranDSLAM
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 2-24).
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

5. Slip the right side of the multislot filler plate (side without the EMI gaskets) into
the receptacle as shown below.
