Removing a Board from a Powered-On System

1. Ensure that the board has been disabled by the ASR software. See "Hot-Plug Feature".

   Once disabled by ASR, one of two results occurs:

   • The three LEDs on the board are not lit (board has no power).

   • The outer two green LEDs are not lit and the middle yellow LED is lit (board in low power mode).

2. 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 3-2).

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

4. If a board is not immediately replaced, a filler panel must be installed in its place.
