Point your browser to the I.P. of the Quintum.
Loke this :http://222.111.333.222
If the option is enabled on the Quintum you will see the welcome screen.
But I will not use the GUI or web browser to set anything on a Quintum.
Not realiable at all.
Get the book and learn CLI. It is time well spent.
Event the new DX series have troubles that only could be fixed trought the CLI.
I have the whole manual on PDF if you need it. Write to mike3799@yahoo and I could reply with the file. About 250 pages and 2.5 mb file.
