Chapter 3: Getting to Know the Router

The Back Panel

The Router’s ports and the Reset button are located on the back panel of the Router.

	Figure 3-1: Back Panel
Internet	This Internet port connects to your cable or DSL modem.
1-8	These eight Ethernet ports connect to network devices, such as PCs, print servers, or
	additional switches.
Reset Button	The Reset button can be used in one of two ways:
	If the Router is having problems connecting to the Internet, press the Reset button for just a
	second with a paper clip or a pencil tip. This is similar to pressing the Reset button on your PC
	to reboot it.
	If you are experiencing extreme problems with the Router and have tried all other
	troubleshooting measures, press and hold in the Reset button for 30 seconds. This will restore
	the factory defaults and clear all of the Router’s settings, such as port forwarding or a new
	password.
Power	The Power port is where you will connect the power adapter.
