SX-200 ICP MX Technician’s Handbook
Feeding Power to IP Phones
The IP Phones require power that can be provided by
• an external supply such as a 24-volt adapter (required by the 5010 and
5020 IP Phone; connects to back of phone) or 48-volt power brick
(required by 5200 series IP Phones; see Figure 6 for connections).
• a multi-port Ethernet Inline Power Module (such as the PowerDsine
24PT Inline Power Unit)
• Layer 2 switches with integral power feed
None of the above are included with the system or phones. All except the
powered Layer 2 switch can be ordered from Mitel. See Appendix B for
part numbers.

Note: Power backup to the IP Phones, the SX-200 ICP, and the Ethernet
switches is required to maintain service during a power failure.
CAUTION:Ensure that the powered cable from the inline power
adapter is installed in the proper connector on the IP Phone. DO
NOT plug it in to the connector (if available) designed for a PC
or other Ethernet devices (Layer 2 port).
