U522 4-Port Ethernet PCI Card
The U522 PCI card is a high-performance 4-Port Ethernet adapter that enables you to
connect a DNCP Series 400/400-CO system to a local area network (LAN). The U522
PCI card is based on a 32-bit bus architecture that optimizes data flow between the
system and the network, resulting in the highest possible throughput with low CPU
utilization.
The U522 PCI card provides both 10 megabits-per-second (Mbps) Regular Ethernet
and 100-Mbps Fast Ethernet communication. The card automatically senses the speed
of the port to which it is attached, and configures itself accordingly.
Each DNCP Series 400/400-CO system can support up to four U522 PCI cards (16
LAN ports). These cards can be paired, using the Redundant Network Interface (RNI),
to provide backup fail-over protection. Figure 1-1 shows the U522 PCI card.
