WARNING: Remove power from the system before making any connections.
CAUTION: Use Electrostatic discharge precautions (be electrically grounded) when
making connections. Electrostatic discharge (ESD) can damage equipment,
although you may not feel, see, or hear it.
Ethernet Connection
When connecting a computer to the DXP Ethernet port, it is vital that you use the correct
Ethernet cables, and that they be properly terminated with the correct pinout. Ethernet
links use Category (CAT) 3, 5e, or 6 unshielded twisted pair (UTP) or shielded twisted pair
(STP) cables, terminated with RJ-45 connectors. Ethernet cables are limited to a length of
328 feet (100 m).
NOTES: • Do not use standard telephone cables. Telephone cables do not support
Ethernet or Fast Ethernet.
• Do not stretch or bend the cables, because this can cause transmission
errors.
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 or pair assignments are swapped.

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 must be properly terminated for your application as either a crossover
or a straight-through cable.
• Crossover cable — Direct connection between the computer and the DXP switcher
• Patch (straight-through) cable — Connection of the DXP to an Ethernet LAN
