Cabling and RJ-45 connector wiring
It is vital that your Ethernet cables be the correct cables, and that they be properly
terminated with the correct pinout. Fast Ethernet links use Category (CAT) 5e
or CAT 6, unshielded twisted pair (UTP) or shielded twisted pair (STP) cables,
terminated with RJ-45 connectors. Ethernet cables are limited to a length 328' (100 m).
N Do not use standard telephone cables. Telephone cables will not support
Ethernet or Fast Ethernet.
Do not stretch or bend cables. Transmission errors can occur.
The cable used depends on your network speed. The switcher supports both
10 Mbps (10Base-T — Ethernet) and 100 Mbps (100Base-T — Fast Ethernet),
half-duplex and full-duplex, Ethernet connections.
• 10Base-T Ethernet requires CAT 3 UTP or STP cable at minimum.
• 100Base-T Fast Ethernet requires CAT 5e UTP or STP cable at minimum.
The Ethernet cable can be terminated as a straight-through cable or a crossover
cable and must be properly terminated for your application (fi gure 2-11).
• Crossover cable — Direct connection between the computer and the
matrix switcher BME 0.
• Patch (straight) cable — Connection of the matrix switcher BME 0 to an
Ethernet LAN.
