CyberPower CP400 is an optional management add-on for selected CyberPower UPS systems. When inserted into the UPS expansion port, the card can communicate with the UPS during a power outage, making it shut down after running on battery mode for 5 minutes. The UPS remains off until a manual switch connected to the terminal on the card is activated, at which point the card triggers the UPS to operate for another 5 minutes.
