Management of PoE Power to PDs
Enterasys 7100G-Series Hardware Installation Guide D-3
When a power supply is added, the device responds to the increase in available power by doing
the following:
1. Detecting the power supply addition and recalculating available power.
2. Subtracting the power capacity for its base system from available power.
3. Distributing remaining power equally for PoE.
Management of PoE Power to PDs
You can configure how the device makes power available to attached powered devices (PDs):
• Real-time mode (default), in which the PoE controller calculates the power needed by a PD
based on the actual power consumption of the attached devices.
• Class mode, in which the PoE controller manages power based on the IEEE 802.3at definition
of the class limits advertised by the attached devices. In this mode, the maximum amount of
power required by a device in the advertised class is reserved for the port, regardless of the
actual amount of power being used by the device.
