Ethernet Communication Ports - GE PACSystems RXi Box IPC User Manual

Ethernet Communication Ports

The IPC provides two RJ-45 Ethernet network port
connectors that support 10BASE-T, 100BASE-TX and
1000BASE-T communications. Either or both of these ports
may be attached to other Ethernet devices. Each port
automatically senses the data rate (10, 100 or 1000Mbps),
duplex (half duplex or full duplex), and cabling
arrangement (straight through or crossover) of the
attached link.
Ethernet Media
The IPC can operate on 10BASE-T, 100BASE-TX or 1000BASE-T media via its network ports. All
three arrangements can use up to 100m of twisted pair cable between each node and a switch,
hub, or repeater.
Note:
10BASE-T: Two pairs of wire are used, one for transmission, and the other for receive.
100BASE-TX: Two pairs of wire are used, one for transmission, and the other for receive.
1000BASE-T: Four pairs of wire are used for simultaneous transmission and receive in both
directions.
Ethernet Port Pin Assignments
Pin No.
Note:
The operation of the Ethernet port LED indicators, ACTIVITY and LINK, is described in chapter 1.
26
The two ports on the Ethernet Interface must not be connected, directly or
indirectly to the same device. The hub or switch connections in an Ethernet
network must form a tree, otherwise duplication of packets may result.
For all three types, shielded twisted pair (STP) cable is required to maintain
CE compliance.

Pin assignments are provided for diagnostic purposes only. Ethernet cables are readily
available from commercial distributors. We recommend purchasing rather than making
cables.
