Introduction

1.6Typical Configurations

The EB152 supports various PCI configurations with different types of devices. Figure 1-3through Figure 1-6show examples of PCI configurations.

The primary bus connector attaches to a PCI slot on the motherboard of the host system or to a secondary PCI bus slot on another EB152. A 5-V or universal PCI option card, or another EB152, can be plugged into any one of the four secondary bus option card slots.

Figure 1-3shows the EB152 with one secondary bus option card.
