Ethernet Connection

This section describes:

•Cabling

•Determining Default Addresses

•Connecting as a Telnet Client

The rear panel Ethernet connector (see figure 53) on the ISM switcher can be connected to an Ethernet LAN or WAN. This connection makes SIS control of the switcher possible using a computer connected to the same LAN.

Cabling

The Ethernet cables can be terminated as straight-through cables or crossover cables (see figure 53) and must be properly terminated for your application:

•Patch (straight) cable — Connection of the ISM to an Ethernet hub, router, or switcher that also hosts a controlling computer

•Crossover cable — Direct connection between the ISM and a controlling computer

6	Orange	Green
7	White-brown	White-brown

A cable that is wired as T568A at one end and T568B at the other (Tx and Rx pairs reversed) is a "crossover" cable.

Straight-through Cable

	End 1	End 2
Pin	Wire color	Wire color
1	White-orange	White-orange

3	White-green	White-green
4	Blue	Blue
5	White-blue	White-blue
6	Green	Green
7	White-brown	White-brown
8	Brown	Brown
	T568B	T568B

A cable that is wired the same at both ends is called a "straight-through" cable, because no pin/pair assignments are swapped.
