■The Gateway has just been started up and is running a self-test routine, or

■The administrator has invoked the Reset to Factory Defaults command, or

■The system software is in the process of being upgraded

In each of these cases, wait until the Gateway has completed the current operation and the alert LED is Off.

Flashing slowly - The Gateway has completed the Reset to Factory Defaults process, and is waiting for you to reset the unit. To do this, remove power, wait 10 seconds and then re-apply power. The Gateway will then enter the start-up sequence and resume normal operation.

If you have used a cable to reset the unit to Factory Defaults, follow steps 5 to 7 in “Forgotten Password and Reset to Factory Defaults” on

page 76.

On for 2 seconds, and then off - The Gateway has detected and prevented a hacker from attacking your network from the Internet.

Continuously on - A fault has been detected with your Gateway during the start-up process. Refer to Chapter 6 “Troubleshooting”.

If the LED is on, the link between the port and the next piece of network equipment is OK. If the LED is flashing, the link is OK and data is being transmitted or received. If the LED is off, nothing is connected, the connected device is switched off, or there is a problem with the connection (refer to Chapter 6 “Troubleshooting”). The port will automatically adjust to the correct speed and duplex.
