Mitel 470 System Manual page 160

Installation
Integrated switch (MiVoice 5370 IP and MiVoice 5380 IP)
You can use the integrated 100Base-T mini-switch to connect other network terminals
(e.g. PC, printer), thereby reducing the amount of cabling required.
Power supply
If your network supports Power-over-Ethernet, the IP system phone is powered directly
via the LAN connection and there is no need to connect the power supply available as
an option.
