Backward Compatibility
Although new features were added, higher power is supported and some algorithms were changed to ensure
interoperability. The idea is that the system will work with legacy Type 1 and Type 2 devices. It should work
automatically, as long as the PSE is capable (in terms of power) of supporting the PD and both are standard
compliant. Should the PD require higher power (IEEE 802.3bt PD) and the PSE cannot support it (IEEE 802.3af
PSE), the PD will either remain off or it will turn on and consume only the power available from the PSE.
The table on PoE backward compatibility is updated every six weeks, after the
take place. The SESPM1040-541-LT-PD requires Type 4 Class 8.
