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 4–6.
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 even
with other director logic cards.
5. If necessary, close and lock the equipment cabinet door.
