4.Disconnect the ribbon cable from the midplane board.

5.Loosen the captive thumbscrews (1).

6.Pull or push against the captive thumbscrews to slide the midplane board toward the rear of the enclosure (2).

7. Tilt the board lengthwise and manipulate it to get it out of the chassis.

To replace the midplane board:

1.Manipulate the board so that it rests flat on the chassis floor, and the standoffs on the chassis floor are visible through the plastic windows in the board.

2.Push firmly against the edge of the board (1) so that the standoffs are hidden under the copper connectors in the plastic windows. The board is now grounded and the midplane is electrically connected to the backplanes.

3.Tighten the captive thumbscrews (2).

4. Replace the fan assemblies, power supply units, and controller module.
