UTP Cable Specifications
To connect to the network, the 3X-DEGXA-xx NICs use the following cable for 1000BASE-
T transmission.
•
Four-Pair Category 5 UTP or better
•
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.
It is highly recommended that users read the "Running 1000BASE-T Gigabit Ethernet over
Copper Cabling" white paper available from the Gigabit Ethernet Alliance Web Site when
considering the use of installed CAT 5 cable or planning for new copper cable installation:

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.
When configured to Auto-Negotiate, the 3X-DEGXA-TA/TB NICs will, during the
initialization/auto-negotiation process, auto-configure themselves when required to provide
an internal cross-over, thus simplifying installation and eliminating the need for cross-over
cables; however, it is highly recommended that a cross-over cable be used to eliminate
possible confusion.
