2.4 Network Communication Interfaces

2.4.1 10BASE-T RJ-45 Pinout

The 10BASE-T Ethernet network 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.

Pin	Name	Description
1	+Tx	+ Transmit Data
2	-Tx	- Transmit Data
3	+RX	+ Receive Data
4	N/C	Not Connected
5	N/C	Not Connected
6	-Rx	- Receive Data
7	N/C	Not Connected
8	N/C	Not Connected

2.4.2 Connecting iServer to PC/Hub/Switch/Router

The iServer’s Ethernet interface can automatically detect the Rx and Tx lines on a twisted pair Ethernet cable (MDI/MDIX Auto Cross). Therefore, to connect an iServer to a PC/Hub/Switch/Router, either a straight-through or a cross-over cable can be used.

On certain devices (like iServer), it is possible for the hardware to automatically correct errors in cable selection, making the distinction between a “straight- through” cable and a “cross-over” cable unimportant. This capability is known as “Auto MDI/MDIX”.

You may need to power recycle for auto detect to take place.
