If a central UPS system is being used to supply power to several computers, data protection for all of the connected devices must be guaranteed in the event of the UPS becoming exposed to critical conditions, such as near-total battery discharge during a prolonged power cut. This can be accomplished by connecting the UPS to the LAN and installing the JNC remote shutdown client on each remote computer powered by the UPS.

JNC is compatible with the following network interfaces:
- Net Vision
- RT Vision
