The figure below shows how to make an Ethernet connection between the router and a network end node.

Important Notes on Ethernet Connections

Observe the following rules when connecting devices with twisted-pair Ethernet cables:

For both end-node and uplink connections, use only EIA Category 5 UTP cables with RJ-45 plugs.

Make sure no cable is more than 100 meters (328 feet) long.

When uplinking two hubs together with a straight-through cable, use an uplink-type jack at one end, and an end-node-type jack at the other.

This is the maximum signal path in twisted-pair Ethernet. Also be sure never to allow a signal loop to form.
