What are the recommended settings for my POE switch?
Check the power output of the Power over Ethernet (POE) switch and the power consumption for each phone you plan on having on the switch 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 in the Administrator Guide.
