Power over Ethernet (POE) switches need to be able to provide sufficient power for the number of phones you plan on running on that switch. You’ll need to check the power output of the POE switch and the power consumption for each phone you plan on having on the switch (this info can be found in the Administrator Guide for your phone) to make sure that the POE power output is greater than the power consumed by the phones on the switch. Depending on how many phones you have, you may need to add POE switches to your network to power all of your phones adequately.

For example:

  • The power consumption for a VVX 500 is 5.0W. 10 phones x 5.0W = a PoE switch that has at *least* 50W.

    Max power consumption for any phone would be 15.4W, which can be used as a safe upper limit if you can’t find the specific power consumption information for your phone model.
