This object lets an SNMP manager cap the total power, as a percentage from 10 to 100 of the midspan's maximum capacity, that all connected PDs together may consume; exceeding this limit can cause the midspan to automatically shut off low- and then high-priority PSE ports. Admins set this to protect against overloading the midspan's total power capacity, accepting that some ports may be automatically disabled if the budget is exceeded. For example, an admin wanting a safety margin below full capacity might set this to 80% rather than 100%, causing lower-priority ports to shed load first if that threshold is approached.
