Power Consumption 4621

[TykeUK]

Can someone confirm the power consumption for 4621SW phones?
I've read somewhere on this forum that is is 12.9 watts but the Avaya website states typical = 4.9, worst case = 6.45!

Obviously these differ quite a bit so would like some clarification.

Many thanks

The 4621SW is a class B device which means that the power range is less than 7 watts and the 1151B power brick is appropriate for this phone.

with the 9600 series phones the power requirements can exceed the class B rating where full 802.3af power complience is required from the PoE switch or, an 1151D brick is required. this is the case with 9640 and multiple expansion modules. there is a new switch on the back of the 9640 to toggle between class b and class c requirements
