Resetting the Linksys Router

The Reset button on the Linksys router enables you to restore the router’s factory 
defaults and clear all of its settings, including any IP addresses you entered.

The Reset button can be used in one of two ways:

If the Linksys router is having connection problems, press the Reset button 
for a moment with a bent paper clip or a pencil tip. This clears up any jammed 
connections and is similar to pressing the Reset button to reboot your PC.

If you are experiencing extreme problems with the Linksys router and have 
tried all other troubleshooting measures, press the Reset button and hold it 
down until the red Diag LED on the front panel turns on and off completely.

Installing the Digi EtherLite Device (S320 Connection Only)

Installation of the Digi EtherLite is required only if connecting to an S320 
controller. The Digi EtherLite is a shared serial device that enables serial ports to 
share a single IP address. The basic requirements to share the serial device are:

The Digi EtherLite device must be physically connected to the Ethernet and 
accessible by both nodes.

The same serial port number must be configured on both nodes.

To install the Digi EtherLite device:

1. Connect the Digi EtherLite to the network using 10Base-T cable to one of the 

available, Trusted LAN Ports on the front end VPN router.

2. Apply power to the Digi Etherlite device.
