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

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

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