Warning
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network
voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some
LAN and WAN ports both use RJ-45 connectors.
Statement 1021
Ethernet Connections
The IEEE has established Ethernet as standard IEEE 802.3. Cisco ISR 4451-Xs support the following
Ethernet implementations:
•
1000BASE-T—1000 Mb/s full-duplex transmission over a Category 5 or better unshielded
twisted-pair (UTP) cable. Supports the Ethernet maximum length of 328 feet (100 meters).
•
100BASE-T—100 Mb/s full-duplex transmission over a Category 5 or better unshielded
twisted-pair (UTP) cable. Supports the Ethernet maximum length of 328 feet (100 meters).
•
10BASE-T—10 Mb/s full-duplex transmission over a Category 5 or better unshielded twisted-pair
(UTP) cable. Supports the Ethernet maximum length of 328 feet (100 meters).
