¿Necesito una subscripción de administración para registrar un sistema en el satélite?

Issue

• Tengo muchos Derechos para Actualizar disponibles en mi cuenta, pero cuando trato de registrar un sistema en el Satellite, me sale un error.

An error has occurred:

Error Message:
    Registration failed: RHN Software service entitlements exhausted: enterprise_entitled
Error Class Code: 91
Error Class Info: Registration token unable to entitle system: maximum membership exceeded
Explanation:
    Your organization does not have enough Management entitlements to register this
    system to Red Hat Network. Please notify your organization administrator of this error.
    You should be able to register this system after your organization frees existing
    or purchases additional entitlements. Additional entitlements may be purchased by your
    organization administrator by logging into Red Hat Network and visiting
    the 'Subscription Management' page in the 'Your RHN' section of RHN.

• No podemos registar ningun sistema. muestra el error "No more management entitlements".
