Removing a Board From a Powered-Off System

1. Use a Phillips #1 screwdriver to mechanically release the board from the system card cage.

   Insert the screwdriver into each quarter-turn access slot (the slots are located on the left and right sides of the board front panel) and then turn a quarter turn so that the arrow points to the unlocked position (Figure 3-3).

2. Pull the ends of both extraction levers outward simultaneously to release the board from the centerplane receptacles (Figure 3-4).

3. If a board is not immediately replaced, a load board (Enterprise 6500 systems only) or a filler panel (Enterprise 4500 and 5500 systems only) must be installed in its place.
