Removing Boards from the VME Card Cage
To remove a VME option board, follow these instructions:
1. Set up an ESD kit (see Chapter 1 for instructions).
2. Shut down your operating system, and then turn off your computer system
power. Refer to your expanding and/or maintaining manuals for instructions, if
necessary.
3. Disconnect any external devices.
4. Release the securing screws on the top and bottom of the board’s air dam, shown
in Figure 3–8. Put the screws in a safe place so you can use them later (on newer
models, do not remove the screws completely from the air dam).

the top ejector handle up and the bottom handle down, as shown in Figure 3–9.
You will feel the board release as the connector leaves the backplane pins.
