PD Disconnect Precedence

After a PD is discovered and powered on an ExtremeSwitching switch, the actual power drain is continuously measured.

If the usage for power by PDs is within the guard band, the system begins denying power to PDs.

You can configure the switch to handle a request for power that exceeds the power budget situation in one of two ways, called the disconnect precedence:
  • Disconnect PDs according to the configured PoE port priority for each PD.
  • Deny power to the next PD requesting power, regardless of that port‘s PoE priority. The default value is deny-port.
