The attached table represents the most widely used PoE standard. Each subsequent newer version of the standard doubles the maximum power of the previous one, while still being backward compatible.
| Property |
PoE |
PoE+ |
UPoE |
| Maximum power on the port |
15.4W |
30 W |
60 W |
| Power on PD |
12.95 W |
25.50 W |
51 W |
| IEEE standard |
802.3af |
802.3 at |
802.3bt type 3 |
| Minimum cable type |
Cat.3 |
Cat. 5 |
Cat. 5 |
Note:
The total amount of power delivered by a switch cannot exceed its budget.
Important:
Some of the power delivered to PDs is dissipated on the cable. For this reason, a minimum guaranteed power on the PD, when the port delivers the maximum power, is also indicated.
The FortiSwitch secure access and rugged series support PoE and PoE+, with some models supporting UPoE. The datasheet for each FortiSwitch indicates its PoE-capable ports and its PoE power budget. The PoE power budget information is also available on the Faceplates tab within the FortiSwitch Ports page.
