2.5 Network Communication Interfaces
2.5.1 10/100 BASE-T RJ-45 Pinout
The 10/100BASE-T Ethernet network
system is used in the iServer for
network connectivity. The 10 Mbps or
100 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.
For CE compliance at 100 Mbps: use shielded cable, opposite end of cable must
be grounded.
2.5.2 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”.
