3-3.2 10/100BaseT Ethernet Local Area Network (LAN) Ports
Two IEEE 802.3 compliant 10/100BaseT Ethernet LAN ports are provided at I/O connector J1. One
port can be connected to an existing on-board LAN or wired server, while the other port can be used
to connect additional computers to the LAN via an Ethernet hub or to enable the connection of a
second CAP unit. Standard (straight-through) connection is used when connecting to an Ethernet
hub. Crossover connection is required when connecting directly to a computer or server, or
connecting to a second CAP unit. Table 3-2 provides cross-reference pin assignment information
between CAP I/O connector J1 and RJ45 male connectors.
