Right after installation, Plesk Panel is in standard mode that supports selling hosting services. You can offer Panel in this state to customers who will use it to resell hosting. When you sell Panel to those who will use it for personal needs, you can offer them Panel in Power User mode – a modification that only allows to run administrator's own hosting accounts and perform server administration actions. This mode does not provide facilities to manage hosting plans, sucbsriptions, resellers and customers.
You can switch Panel to Power User mode right after installation is completed, or later if it does not have customer or reseller accounts. You can switch Panel back to standard mode any time.
You can switch Panel to Power User mode and back by running a command-line utility or by sending a particular API RPC packet.
For more information on Panel modes, see section Becoming Familiar with Parallels Plesk Panel of Administrator's Guide.
To switch Panel to Power User mode via Panel command line utility:
/usr/local/psa/bin/poweruser --on -ip <ip-address> -domain <domain_name>
%plesk_bin%\poweruser.exe --on -ip <ip-address> -domain <domain_name>
where
<ip-address> is the IP address allocated to administrator's default hosting account. This option is required in case there are no subscriptions belonging to administrator.<domain_name> is the domain name to be linked to the specified IP address. If the -domain option is not specified, the server host name will be used. The option makes sense only when used together with -ip. To switch Panel back to standard mode via Panel command line utility:
/usr/local/psa/bin/poweruser --off
%plesk_bin%\poweruser.exe" --off
