• One or both LAN states could be set to off.

analyzer has been proven to be working properly, concentration can be placed on the network itself to
determine the cause of the failure.

an RJ-45 connector on each end.
NOTE Pins 1, 2, 3, and 6 of the connectors must be located to determine which wires to cut in the
following steps. Most, but not all, LAN cables use the color coding listed in
