Ethernet Connectors and Cables
This section describes the Ethernet connectors and cables for the NP access card and the Ethernet access card.
15-pin Ethernet AUI Connector
Figure 3-23 is a schematic diagram of the 15-pin Ethernet AUI connector for the NP access card and the Ethernet access card (ports 0 and 7).
The data cable for this connector is described in the section "Ethernet AUI Data Cable " later in this chapter.
Interface connector type: AUI DB15 connector
AUI connectors per NP access card: one
AUI connectors per Ethernet access card: 2 (numbered 0 and 7)

Ethernet 10Base-T (RJ-45) Connector
Figure 3-24 shows the RJ-45 connectors and pinout assignments on the Ethernet access card. These connectors are used by the twisted pair (10Base-T) ports.
The cables used with these ports are described in the section Ethernet 10Base-T Straight-Through Cable and the section Ethernet 10Base-T Crossover Cable .
