Connecting the power supply
If your LAN supports Power-Over-Ethernet (PoE), the phone will be powered via the
LAN cord and you will not require a power adapter.
If your LAN does not support PoE or if you have installed a switch between the LAN
and the phone that does not support PoE, you will need the optional power adapter
to power the phone.
• Plug the round connector of the power cord on the underside of the phone into
the power socket.
• Desk installation only: To relieve the strain on the cable feed the cable through one
of the cable guides on the stand rest.
• Connect the power supply to the mains.
Logging the IP phone
Your system administrator has to prepare the system before you can log on your
phone.
Note:
Only use the optional original plug-in power adapter.
