POWER REQUIREMENTS FOR 5220 IP PHONE OPTIONAL
ACCESSORIES
The 5220 IP Phone and the 5220 IP Phone (Dual Mode) support optional accessories which
are powered in different ways depending on the option and the phone:
• 5220 IP Phone options are powered from a 24 VDC power unit only.
• 5220 IP Phone (Dual Mode) options can be powered from either 24 VDC power unit or
through the Ethernet.
CAUTION: The 5550 IP Console and the 5310 IP Conference Unit can only be
powered with AC adapters that provide a 24 VDC output. To prevent damage do
not use PoE or an In-Line Ethernet AC Power Adapter to power either of them.
Note: To determine whether your phone is a 5220 IP Phone or 5220 IP Phone (Dual
Mode), check the label on the back of the set. 5220 IP Phone (Dual Mode) sets are
identified as either "5220 Dual Port" or "5220 Dual Mode".
An alternate way of identifying whether a phone is dual mode or not is by the "Top Engineering
Number" which can be found on a label on the back of the phone.

SYSTEM POWER REQUIREMENTS

ICP power requirements are detailed in the 3300 ICP Hardware Technical Reference Manual.
This document is available via Mitel On Line.
Note: During a local power failure, data being written to a disk or FLASH module may
not be completely stored and therefore could become corrupted. Use of RAID can
improve the integrity and data validation, but cannot guarantee data that wasn't
completely transferred due to loss of power. Systems most affected would be those
undergoing updates, or those that store voice mail. We strongly recommend that these
systems, including the ICPs, be powered through UPS units or similar power backup
systems. More details on platform power consumption and settings can be found in the
3300 ICP Hardware Technical Reference Manual.
