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.
