Phase II IP Phones have integrated hardware to support power over Ethernet
for 802.3af standard power. Nortel recommends Power over Ethernet
deployment since it allows for power backup in case of power failures. Note
that, with Phase II IP Phones, power splitters are no longer needed to support
Power over Ethernet.
Phase II IP Phones, IP Phone 1110, IP Phone 1120E, IP Phone 1140E, and IP
Phone 1150E also support connection to AC local power using the
appropriate adapter. If local power using the AC adapter is required, the AC
adapter must be ordered separately. If the network LAN infrastructure
supports Power over Ethernet, an AC adapter may not be required.
Note 1: You must order a country-specific power adapter. See the
IP Phone components list table in the applicable IP Phone chapter for AC
adapter descriptions and product codes.
Note 2: If you are using local power with the IP Phone 1110, IP Phone
1120E, IP Phone 1140E, or IP Phone 1150E, you must use the AC
adapter (model # N0089601) only.
