Figure 6-2.
 Note:
Put away the removed blank panel for future use.

1) Wear the ESD-preventive wrist strap and loosen the captive screws on the board
with the screwdriver.
2) Hold the ejector levers on the board with both hands and pull them outward
simultaneously to separate the connectors of the board from the backplane.
3) Gently slide the board along the guide rails out of the slot.
 Note:
If you are not going to install a new board after removing the board, install a blank panel
in the slot for dust-proof purpose.
