PSE allocated

PSE allocated power value

  • Power=0.1*(decimal value of bits) Watts. The value is an integer that ranges from 1 to 255. For example, if the value of the field is 255, the exchange power is 25.5 W.
  • When the PoE power is sufficient, the values of PD Requested Power value and PSE allocated Power value are the same.

 PoE over LLDP Power Negotiation Mechanism

If PoE over LLDP power negotiation function is enabled on PSE, the PSE and the PD will periodically send LLDP packets to each other to perform LLDP power negotiation once the PD device is detected by the PSE. PoE over LLDP power negotiation starts when PSE receives LLDP packets from PD.

...

  • All PoE devices support PoE over LLDP power negotiation function, except for S5810-48TS-P, S3410L-24TF-P, S5860-24XB-U, 3410C-16TMS-P, 3410C-16TF-P, S3410C-8TMS-P and S3270-24TM-P.
  • Enable LLDP function and PoE function before using PoE over LLDP power negotiation.
