4. Unpack the subcard.
To install a subcard:
1. Turn the ejector levers of the subcard outward simultaneously with both hands, and then slide
the subcard (with the right side up) straight into the SPE card along the slide rails until the
ejector levers touch the panel of the SPE card, as shown in Figure 15.
2. Push against the front panel of the subcard. When the front panel is close enough to the SPE
card, pivot the ejector levers of the subcard inward with both hands so that the front panel is
flush with the panel of the SPE card.
3. Use a Phillips screwdriver to fasten the mounting screws on the subcard.
