Replacing the Expansion-Card Cage
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System
Information document.
1. With the expansion-card cage lever in the upright position, lower the cage into the chassis until it is aligned with the
tabs on the chassis side wall (see Figure 6-3 ).
2. Rotate the expansion-card cage lever down until the handle is flush with the top of the cage, and the cage is secured in
the chassis (see Figure 6-3 ).
3. Reconnect all expansion-card cables.
4. Replace the cover (see " Replacing the Cover " in "Troubleshooting Your System").
Expansion Cards
The system includes three expansion slots. The expansion cards are installed on the system's riser board (see Figure A-4 to
identify the expansion slots).
Expansion Card Installation Guidelines
You can install expansion cards of different operating speeds on the same bus; however, the bus will operate at the slowest
operating speed of the cards on that bus. For example, if one card on the bus has an operating speed of 66 MHz and the
other card has an operating speed of 100 MHz, the bus will only operate at 66 MHz.
To identify expansion slots and PCI buses, see Figure A-4 . Table 6-1 lists the PCI bus and operating speed for each
expansion-card slot.
