Nortel Contivity 1750 password unknow and maybe ip static unknow

Nortel Contivity 1750 password unknow and maybe ip static unknow

Nortel Contivity 1750 password unknow and maybe ip static unknow

Hi all !

If you bought an contivity 1750 and the seller don't supply any data about it, there is a way to reset password of this unit ?

If ever the unit had a static IP setted and don't get any ip from the DHCP on the new network, there is a way to sniff the ip setted and make a lan only to access it web interface ?


RE: Nortel Contivity 1750 password unknow and maybe ip static unknow

default username and password: admin/setup

If these don't work you will need to use a recovery disk to default the switch.

If the administrative password is lost, the Nortel VPN Router can be set back to factory defaults using the
method described.

All of the following requires that the Nortel VPN Router have an assigned management IP address to allow GUI
access to it. If the management IP address is not known, perform a trace on the private interface during a restart. An
ARP will be sent out for the interface address and another for the management IP address. If the box has not been
assigned an IP address this method cannot be used, and Nortel Technical Support must be contacted.

1. Place the Recovery Disk into the Floppy Disk Drive and Restart. Startup in Recovery mode using a floppy
disk is longer than with the diskless VPN Routers or 600, which all use Recovery images stored in Flash.
2. Once the startup is complete (this can be monitored using the console if desired), open a web browser and
direct it to the management IP address to open the GUI. Note that opening the GUI in Recovery mode is a
lengthy process on systems using a Recovery disk.
3. Once there, select the radio button marked Restore original factory settings and click the Restore button.
4. When the message “Successful Factory Restore” appears at the top of the screen, remove the Recovery
Disk from the Floppy Disk Drive and perform a restart. It is now at Factory Default. The administrator userid
will be returned to admin, with the password returned to setup. As the management IP address is no longer
present, the console must be used to enter both the management and private interface IP addresses.
