1) Although no longer available, the phone is still supported.
2) An MiVoice M535 always requires a power supply unit
3) The value applies to radio units with hardware version "-2". The value for hardware version "-1" is 300 mW
lower.
4) The value applies to each interface and to radio units with hardware version "-2". The value per interface for
radio units with hardware version "-1" is 150 mW lower.
5) The value applies to phones with hardware version "-2". The value for phones with hardware version "-1" is
60 mW lower.
6) The value depends greatly on the terminal type.
Tip
With the planning application Mitel CPQ the power supply available for terminals is checked
automatically.
Overload shutdown
If the rated power is exceeded the power supply is disconnected. It is restored after ap-
prox. 20 s.
If an overload occurs, reduce the required supply power (e.g. by powering DECT radio
units and/or system phones locally).

Power supply per terminal interface

The power supply per terminal interface is determined by the interface type. The inter-
face load depends on the following variables:
• Terminals used incl. auxiliary devices
• Bus configuration
• Line length and conductor cross-section
For information on the calculations refer to "Terminal interfaces", page 114.
