The OptiPlex GX1/GX1p mini tower computers have seven expansion-card

slots. The riser board has four ISA expansion-card connectors and five PCI

expansion-card connectors. Two PCI expansion-card connectors share

expansion-card slots with two ISA connectors, resulting in a total of seven

expansion-card slots (see Figure 1-11). The riser board is active, incorporating

PCI-to-PCI bridging.

The mini tower riser board includes the P1 connector (for connecting the NIC

to the riser board cable) and an LED. If the LED is on, the riser board is receiv-

ing power; if off, the riser board is not receiving power.

and secondary L2 cache memory are implemented in an SEC cartridge/heat

sink assembly. Upgrade to a higher-performance microprocessor is accom-

plished by snapping out the old assembly and installing an upgrade assembly

as higher-performance microprocessors become available.
