4.7.1. SetPortEnable
Set if a port is allowed to turn on.
Prototype:
Parameters:
Return Value:
If Enable is zero, the port is disabled and is not allowed to power on. If Enable is one, the port is enabled and is
allowed to power on.
4.7.2. GetPortEnable
Get if a port is allowed to turn on.
Prototype:
Parameters:
Return Value:
4.7.3. SetPortCapability
Set if a port can supply high power.
Prototype:
Parameters:
Return Value:
Table 18 lists the Port Capability values.
If the port hardware is designed to supply high power (PoE+), set Capability to one. Otherwise, set
Capability to zero.
A port's capability cannot be changed while the port is on. This is a limitation of the Si3452 port controller.
