以下是PSE-QD及PSE-HQD的幾個主要重要特色：
� IEEE802.3af compliant.
� Per Port maximum output – PSE-QD, 450mA; PSE-HQD, 650mA.
� PSE-HQD supports high power mode and backward compatible to normal power mode.
3 b+ D) N; p8 q) c, ]% n9 S2 o� Support DC disconnection.
� Maximum total power protection.
- N3 S: w' f$ y% j4 j� Support PD power classification from class 0 to class 4.
