You need to purchase one additional device CAL for every network engine added to your Metasys system. You may also need to purchase additional user CALs as you expand the number of authorized Metasys system users. If you currently have an ADS and you expand your system to require more than 10 connections, you must upgrade to an ADX and purchase the appropriate number of CALs.
For CAL purchasing information, log in to the Johnson Controls employee portal website, go to the Tools & Applications page, then click the Computer Price List link in the Procurement/Purchasing section. This page contians the necessary information on how to access the Insight/Johnson Controls website (http://www.insight.com/jci) that contains information about purchasing CALs.
When you purchase CALs, you receive a paper certificate from Microsoft. There is no method in the operating system to designate or configure the number of device or user CALs. So make sure you keep the Microsoft CALs certificate in safekeeping at the customer site in case of an audit. You may be subject to a fine if a security audit reveals that your system is not correctly licensed.
If Metasys system software is purchased separately, the customer is responsible for purchasing the correct number of CALs and for properly designating each CAL. A device CAL cannot be transferred to a user CAL, or vice versa. If a Metasys ADS/ADX Ready computer is purchased, the proper number of CALs come with the purchase, so no additional CALs are required. You must purchase additional CALs if the number of devices exceeds 5 or 10, depending on the size of the purchased Metasys system. Ultimately, the customer must determine how to split the total number of CALs between device and user.
