Upload configuration file for registration

I´d like to know which is the link to upload the configuration file generated over the registration wizard. I´ve been looking for it, but i haven´t found it.

It´s a new VNX 5300 installation and I´m having problems to download the lastest upgrades for the block and file with the USM, and I guess that it´s due to I haven´t done correctly the registration proccess.

Thanks
