A customer plans to connect 40 Voice over IP (VoIP) phones and 8 security cameras to a switch:
The VoIP phones are Class 2 PoE devices and require a maximum of 45W (draw a maximum of
5w)
The security cameras are Class 4 PoE+ devices and require a maximum of 17W (draw a
maximum of 20 W)
The network architect is proposing an HP 5500-48G-PoE switch, which supports PoE and PoE+
and has a PoE power budget of 370W
The customer and architect agree on the class form of power allocation
What else does the solution require?

A.
A management module that is PoE+ capable

B.
A redundant power supply for the switch that enhances the PoE/PoE+ budget

C.
A power converter that enables the switch to provide PoE and PoE+ power at the same time

D.
A 208-220V input power service
