Connecting the Power
The Cisco 500 Series IP phones do not ship with power supplies. If you are not
using Power over Ethernet (PoE), you must order a Cisco PA100 power supply for
each phone.
If you are using Power over Ethernet (PoE) to power the phone, the phone receives
power when you connect an Ethernet cable from the phone SW port to a switch
that provides PoE. If you are using a Cisco PA100 power adapter, insert one end of
the power adapter into an outlet and insert the other end into the power port on
the phone body.
