CAUTION
Phone Damage Hazard. To avoid damaging the IP phone, make sure the IP phone is connected to the proper power
supply before powering on. Contact your system administrator for more information.
The IP phone requires any one of the following power supplies:

Mitel 48-volt DC Ethernet power adaptor 100-240 volt AC 50-60Hz (ES), part number 50005301

An industry-standard IEEE 802.3af Power over Ethernet (PoE) power supply unit

IEEE 802.3af compliant Gigabit power supply, part number 51015131
If your IP phone uses a centralized PoE power supply unit, do not use the 48-volt DC Ethernet power adaptor. If
necessary, contact your system administrator for assistance before connecting your IP phone to the centralized power
source.
Make sure the IP phone is plugged into an uninterruptible power supply (UPS). If your IP phone is plugged into the
UPS and the power fails, it should remain powered on for about 10 minutes. If the IP phone is not plugged into a UPS
and the power fails, the current call is dropped and you will not be able to use the IP phone until the power is
restored.
CAUTION
Phone Damage Hazard. Do not use your IP phone or disconnect it from the power supply while it is updating
software.
The IP phone may require occasional software updates when new versions are available. The IP phone is configured
to download the updates automatically. Contact your system administrator for more information.
