UTP Cable Specifications
To connect to the network, the NC7170 Server Adapter uses the following cable for
1000Base-T transmission.
• Category 5 UTP or better twisted-pair
• 22-26 AWG, 100Ω @ 1MHz
• EIA/TIA 568a or EIA/TIA 568b
Using UTP Category 5 Cable in Gigabit over Copper Installations
For Gigabit over copper installations, Category 5 UTP or better 1000Base-T cable must
comply with the IEEE 802.3ab 1000Base-T standard. For new installations, Category 5e
(enhanced Category 5) or better cable is recommended. Maximum distances for Gigabit over
copper cable are 100 meters (328 feet).
RJ-45 Pinouts and Crossover Function
The Ethernet standard also specifies that each segment implement a crossover function to
connect the transmitter of one device to the receiver of a device at the other end, and vice-
versa. The crossover function may be implemented internally at the hub or switch, or
externally through the twisted-pair media.
