Preparing for Network Connections
When setting up your router, consider distance limitations and potential electromagnetic interference
(EMI) as defined by the applicable local and international regulations.
Network connection considerations are provided for:
• Ethernet Connections, page 2-14
See the following online document for more information about network connections and interfaces:
• Cisco Modular Access Router Cable Specifications
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).
See the Cisco Modular Access Router Cable Specifications document at Cisco.com for information
about Ethernet cables, connectors, and pinouts.
