Chapter 2 Preparing to Install the Router Preparing to Connect to a Network 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. Table 2-2 lists the router models described in this guide and summarizes the LAN interfaces supported on each model.

The Cisco 2613 router provides a single Token Ring interface. (See Table 2-2.) The IEEE has established Token Ring as standard IEEE 802.5. Specifications indicate a maximum segment distance of 328 feet (100 meters) for UTP cabling. OL-2171-06 Cisco 2600 Series Routers Hardware Installation Guide 2-9
