Replacing a UPM Filler Blank

To replace a filler blank:

1. Remove the filler blank from its packaging.

2. Hold the filler blank by its stiffener and insert it in the chassis card track, as

shown in Figure 77.

3. To secure the filler blank, sequentially insert the torque tool into each locking

Allen screw. Turn each screw clockwise until you feel the torque tool release

and hear a clicking sound. As each screw turns clockwise, the filler blank

locks into place.

4. Verify the filler blank stiffener is flush with the front of the card cage and is

even with other director logic cards.

5. If necessary, close and lock the equipment cabinet door.
