6. Replace the expansion-card cage.
7. Connect any cables that should be attached to the card.
8. See the documentation for the card for information about the card's cable connections.
9. If you are installing the entry-level OptiPlex sound card, disconnect the internal speaker cable from the system board and reconnect it to the
INT SPKR connector on the sound card. You may have to route the speaker cable through a hole in the front of the chassis to reach the sound
card connector.
10. Replace the computer cover and reset the chassis intrusion detector.
Riser Boards
The midsize chassis is available with either a PCI riser board (see Figure 19) or a PCI/ISA riser board (see Figure 20). The PCI riser board
provides five PCI expansion card slots. The PCI/ISA riser board provides two PCI expansion slots, two ISA expansion slots, and one shared
PCI/ISA expansion slot.

Memory
To remove a Rambus in-line memory module (RIMM), perform the following steps:
1. Remove the computer cover.
2. Rotate the system power supply to allow you to access the RIMMs.
3. Press the securing clips outward simultaneously until the RIMM disengages and pops out slightly from the socket (see Figure 21).
