Legacy Devices

ExtremeXOS software allows the use of non-standard PDs with the switch. These are PDs that do not comply with the IEEE 802.3af standard.

The system detects non-standard PDs using a capacitance measurement. You must enable the switch to detect legacy devices; the default value is disabled. You configure the detection of legacy PoE devices per slot.

Detecting a PD through capacitance is used only if the following two conditions are both met:
