ZyXEL Communications How to Change Your Zyxel Router Password and Perform Zyxel Password Recovery

IES 1248 Support Notes

I forgot the Password, how do I recover it?

a.) IES-1000

Please use the BOOTP/TFTP and bin file to recover the configuration to factory default. Please refer to IES-1000's user manual to see the recovery procedure within Chapter 36.2 'BOOTP/TFTP Firmware Recovery of the Network'. All of your former configurations will recover to factory default. The default password is 1234.

b.) IES-2000/3000/1248

The only solution is to reset the password to default '1234' by

resetting the whole IES-2000/3000/1248 configurations. To reset the settings you need to upload our default configuration file (*.rom). Please

read through the following steps to do it.

1.Connect your IES-2000/3000/1248 console port to PC's serial port.

2.Start a Terminal program with 9600bps, N/8/1 settings.

7.Extract the *.rom file in the zip to your hard disk.

8.Type 'atlc' command in debug mode to start to upload the *.rom file.
