Power Requirements
The IP phone requires
any
one of the following power supplies:
Inter-Tel Power Supply Unit, part number 806.1114 or 806.1117 (Europe), or Mitel Universal Power Supply Unit,
part number 828.1766
Red Hawk Single Port PowerSense
TM
, Part Number 901.0407
An industry-standard IEEE 802.3af Power over Ethernet (PoE) power supply unit
If your 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 phone to the centralized power
source.
Make sure the phone is plugged into an uninterruptible power supply (UPS). If your phone is plugged into the UPS
and the power fails, it should remain powered on for about 10 minutes. If the 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 phone until the power is restored.
Software and Firmware Updates
If you are using an IP phone, it IP may require occasional software updates when new versions are available. The
phone is configured to download the updates automatically. Contact your system administrator for more information.
During the download process several messages are shown on the display that indicate the status of the download.
The final display message, FIRMWARE DOWNLOAD SUCCESS or BOOT DOWNLOAD SUCCESS, indicates that
the software or firmware update was downloaded successfully.
Immediately following the download your phone will re-synchronize with the telephone system by performing a reset.
When the display returns to your extension number, your user name, the time of day, and the date, the reset is
complete and you can use your phone again. During a reset, your phone (and all connected devices) lose
connectivity with the network for approximately 10 -20 seconds.
Software Compatibility
Depending upon which software version your telephone system is using, some of the features included in this guide
may not be available for your phone. Check with your system administrator to see which software version your
telephone system currently uses and if there are any feature restrictions for your system.
