The standard '''IEEE 802.3af''' specifies how to supply power to compliant devices over Ethernet LAN cabling (10/100Base-T).
Armed with uninterruptible power supplies (UPS), Voice over IP (VoIP) phones, like:

* [[optiPoint 410/420]]
* [[optiPoint 410/420 S]]
* [[optiPoint 150 S]]

are so deployable without worrying about them not functioning during a power outage.

=== IEEE 802.3af Power Classes ===

The '''IEEE 802.3af''' standard allows for the classification of '''PD'''s ('''P'''owered '''D'''evices) based upon their power requirements to permit load management.

Below the power classes defined by IEEE 802.3af:

{| {{DefaultTable}}
! Class
! Measured current (mA)
! Maximum PD power (W)
|-
| 0
| 0 to 5
| 12.95
|-
| 1
| 8 to 13
| 3.84
|-
| 2
| 16 to 21
| 6.49
|-
| 3
| 25 to 34
| 12.95
|-
| 4
| 35 to 45
