Required Tools and Equipment for Installation and Maintenance
Prepare 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 the Ethernet IEEE 802.3 Standards. The routers 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.
