		Making the Physical Connections 2-5
The following table describes all the Netopia R2020 Dual Analog Router back panel ports.
	Port	Description
	Power port	a mini-DIN8 power adapter cable connection.
	Line 1 port	a red RJ-11 telephone jack labelled “Line 1".
	Console port	a DE-9 Console port for a direct serial connection to the console screens. You
		may use this if you are an experienced user and choose not to use SmartStart.
		See “Connecting a local terminal console cable to your router” on page 5-3.
	Auxiliary port	an HD-15 Auxiliary port for attaching an external modem or the optional
		AppleTalk kit.
	Line 2 port	a red RJ-11 telephone jack labelled “Line 2".
		If you have only one telephone wall jack, supporting either one or two telephone
		numbers, use the “Line 1" port. “Line 1" supports two phone connections on a
		single line; “Line 2" supports a single phone connection.
	Crossover switch	a crossover switch with Normal and Uplink positions. If Ethernet Port #1 is used
		for a direct Ethernet connection between a computer and the router, set the
		switch to the Normal position. If you are connecting the router to an Ethernet
		hub, use Ethernet port #1 on the router and set the switch to the Uplink
		position.
	8-port Ethernet hub	Eight Ethernet jacks. You will use one of these to configure the Netopia R2020.
		For a new installation, you use the Ethernet connection. SmartStart only works
		over Ethernet. Later, if you want to do some advanced configuration, you can
		Telnet to the Console-based management screens via the Ethernet connection.
		You may also use the Console connection to run the Console-based
		management using a direct serial connection. You may either connect your
		computer directly to any of the Ethernet ports on the router, or connect both
		your computer and the router to an existing Ethernet hub on your LAN.
