Preparing to Connect to a Network Chapter 2 Preparing to Install the Router Preparing to Connect to a Network 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 several types of network interfaces and are described in the following sections: • Ethernet Connections, page 2-8 • Serial Connections, page 2-9 Refer to the following online documents for more information about network connections and interfaces: • Cisco Network Modules Hardware Installation Guide • Cisco Interface Cards Installation Guide • Appendix B, "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. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. Ethernet Connections The IEEE has established Ethernet as standard IEEE 802.3. The most common Ethernet implementations are as follows: • 100BASE-T-2-pair Category 5 or unshielded twisted-pair (UTP) straight-through RJ-45 cable. • 10BASE-2-Ethernet on thin coaxial cable, also known as thin Ethernet. The maximum segment distance is 607 feet (186 meters). • 10BASE-5-Ethernet on thick coaxial cable, also known as thick Ethernet. The maximum segment distance is 1,640 feet (500 meters). • 10BASE-T-Ethernet on unshielded twisted-pair (UTP) cable. The maximum segment distance is 328 feet (100 meters). UTP cables look like the wiring used for ordinary telephones; however, UTP cables meet certain electrical standards that telephone cables do not meet. Refer to theAppendix B, "Cable Specifications" for information about Ethernet cables, connectors, and pinouts.

Preparing to Connect to a Network
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 several types of network interfaces and are
described in the following sections:
•
Ethernet Connections, page 2-8
•
Serial Connections, page 2-9

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. To see translations of the warnings that appear in this
publication, refer to the
Regulatory Compliance and Safety Information
document that accompanied
this device.
Ethernet Connections
The IEEE has established Ethernet as standard IEEE 802.3. The most common Ethernet implementations
are as follows:
•
100BASE-T—2-pair Category 5 or unshielded twisted-pair (UTP) straight-through RJ-45 cable.
