Pd Type - Planet GSD-1222VHP User Manual

2.3.5 PD Type

Changing the PoE power-up mode can let non-standard PDs pass the procedures
of PoE power delivery process. This way, the switch can supply power to non-
standard PDs. The GSD/GSW 802.3at PoE+ Switch series can set the PoE power-
up mode to be in Enhance mode, Standard mode or Legacy mode by the user
interface.
Object
On the basis of standard mode, change the PD of class 0 to
Enhance
AT mode; in addition, the current surge limit during power up
(default)
increases to the current limit of AT.
Standard Fully conforms to the IEEE 802.3 af/at standard.
The legacy detection is to identify the PD devices that did not
follow the IEEE 802.3af standard and their unique electrical
Legacy
signatures, in order for the PoE switch to provide the power to
those PD devices.
