Systems or packages can be purchased that come with their own set of predefined subscriptions. This can be for machines purchased from a hardware vendor or even for machines and software provided internally, with subscriptions granted through a subscription management application.
Rather than attaching new subscriptions to a system, these existing subscriptions can be redeemed or activated. A 16-digit number called an subscription number is generated when these subscriptions are created, and that key is then submitted to redeem those subscriptions.
In the Subscriptions > Overview page, click the Activate a subscription link in the upper right of the Summary area.
In the Subscription Activation page, enter the 16-digit subscription number.
Continue through the activation wizard.
