Replacing the Expansion-Card Cage

Use the following procedure to replace the expansion-
card cage:
1. With the securing lever in its extended position,
align the tabs on the left and right sides of the
expansion-card cage with the slots on the back
and bottom of the chassis (see Figure 7-6). Slide
the expansion-card cage into place.
2. Rotate the securing lever inward until it is flush
with the side of the chassis. Make sure the riser
board is fully seated in the RISER connector on
the system board.
3. Reconnect any cables you removed in step 2 of the
previous procedure, "Removing the Expansion-

labeled "RELEASE —>," and rotate it upward

the power supply up in one of several extended posi-
tions, which are especially useful when working
with the chassis standing upright.
