Powering the phone
The Aastra 5360, Aastra 5361 Aastra 5370 and Aastra 5380 system phones are nor-
mally powered via the DSI bus. However there are several reasons that require pow-
ering with a plug-in power supply:
• Long line
• 2 phones on the same bus
• 1 or more expansion key modules on the phone
• Terminal power supply of the communication server is overloaded
Only use the corresponding plug-in power supply unit with FCC connector availa-
ble as an option. It is connected either to the phone itself or, when using one or
more expansion key modules, on the last expansion key module.

wire diameter, and the power input of the system phones are described
in the chapter
"Terminal interfaces DSI", page 109
