2.4 Network Communication Interfaces
2.4.1 10Base-T RJ-45 Pinout
The 10BASE-T Ethernet network (RJ-45) system is used in the iServer for network
connectivity. The 10 Mbps twisted-pair Ethernet system operates over two pairs of wires.
One pair is used for receiving data signals and the other pair is used for transmitting data
signals. This means that four pins of the eight-pin connector are used.

2.4.2 10Base-T Crossover Wiring
When connecting the iServer directly to the computer, the transmit data pins of the
computer should be wired to the receive data pins of the iServer, and vice versa. The
10Base-T crossover cable with pin connection assignments are shown below.
