Some concurrent licenses can be borrowed. Borrowable license enable you to use a product when your computer is not connected to the License Server. For example, if you have your product installed on a laptop computer, but will be away from the office, you can borrow a license to use the product while you are away.
The product must be connected to the License Server in order to borrow a license. The method you use to borrow a license depends on the product you are using. Please see your product documentation for more specific information.
When you borrow a license, you do so for a set period of time. If you have not returned the license before the end of the borrow period, the license is automatically returned to the License Server when next connected to it. See Maximum Borrow Period for instructions.
