Step 2 Connect the other end to a 10-, 100-, or 10/100-Mbps port on the hub or switch. The router senses the port speed and duplex mode and then operates at the same speed and duplex.

Caution Always connect the Ethernet cable to the yellow ports on the router. Do not connect the cable to an ISDN S/T or U port (on a WAN interface card) or to an NT1 that is connected to a WAN interface card. Accidently connecting the cable to the wrong port can damage your router.
