it's not the MAC address of the G450, rather the MAC address of the S8300C.
to get to it, do this:
under the "maint web page", click on "SIP enablement server", once you are into that screen, enable it.
In about 5-10 minutes, after it is enabled, you will have another choice on the main page pull down, it will be "SIP server"\
go into the SIP server page, and click on licensing, and then when in that page, click "WebLM". Once you launch the Web License Manager, you have to login, and it will force yuo to change the password. The login is "admin", the passwword is "weblmadmin". I usually reset the password back to the default of "weblmadmin". now when you login for the 2nd time, it will be asking you for a license. ignor this for now, click on "server properties", and you will see a list of 5 MAC address's. the firs ton eit gives you is useless, since it changes on each boot.
The next MAC cuold be used, and the next 3 are all the same. I use the MAC address that has 3 copies, but the 2nd one will work as well.
Now you need to get into RFA, with an RFA SIP Enablement transaction #, and the MAC address you just found, to complete the licnese. once you complete the license in RFA, have it email to you, then you can take the XML file and copy it to your local PC
Then you browse for this file in the WebLM interface, and click on "install"
simple really, isn't it?
