AP WAX630E PoE++ injector or switch

The 802.3bt standard does describe these common type classes.

802.3bt Type 3, 4PPoE aka PoE++, 60W at the PSE, 51W available at the PD

802.3bt Type 4, 4PPoE aka PoE++, 90W at the PSE, 71W available at the PD.

Off the fixed Types, implementations 802.3bt (based on LLDP, not using Type signals) exist with

30W at the PSE, 25.5W available at the PD 

45W at the PSE, 40W available at the PD 

75W at the PSE, 62W available at the PD 

PSE: Power Source Equipment

PD: Powered Device

What Netgear shows with 60W is the minimum standard 802.3bt Type 3 variant, not the effective requested and drawn power. Some PSE design inherit strict type based power allocation and reservation, the flexible variant is more common in the 802.3bt PoE++ PSE switches. For the effective numbers, please consult the WAX630E Data Sheet.

The current drawn by the PD during classification is called the classification signature or classification current. The IEEE PoE specification defines five classifications signatures the PD is allowed to draw during classification.

As such, enabling a PoE power delivery is a multi-stages process. Variations can exist with the different vendors, where the negotiation can be not successful - something to check with the vendors involved.
