Ethernet Wiring
Use data-quality (not voice-quality) twisted pair cable rated category 5e (or better) with standard
RJ45 connectors. Straight-through or crossover Ethernet cable can be used for all devices the
switch is connected to because all the ports are capable of auto-MDI/MDIX-crossover detection.
The RJ45 Ethernet port connector bodies on these products are metallic and connected to the
Chassis GND terminal. Therefore, shielded cables may be used to provide further protection. To
prevent ground loops, the cable shield should be tied to the metal connector body at one end of
the cable only. Electrical isolation is also provided on the Ethernet ports for increased reliability.
