I changed the default accounts passwords including Administrator to new passwords in the Security Settings. When I next logged into manager the Secondary server was showing an authentication error, i logged into it and updated the Administrator password and it was ok. The 3 IP500v2 gateways attached are now showing offline in manager, but ok in the web management and functioning ok. If i log into them individually with System Status I can confirm they are still on the old Administrator password. How do you log in to the IP500v2 and update the password to current as the security settings is just against the primary server?
