Gigabit Ethernet RJ-45 Port Pinouts

The Cisco 7201 router has RJ-45 ports for the two 10/100/1000 Gigabit Ethernet/Fast Ethernet/Ethernet
connections. In addition, the Cisco 7201 router has an RJ-45 Fast Ethernet Management port. The RJ-45
ports support IEEE 802.3ab (Gigabit Ethernet) and IEEE 802.3u (Fast Ethernet) interfaces compliant
with 10BASET, 100BASETX, and 1000BASET specifications.
The RJ-45 ports support standard straight-through and crossover Category 5 UTP cables with RJ-45
connectors. Cisco does not supply Category 5 UTP cables; these cables are available commercially.
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network

LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021
