Figure 4 Powering Option for 4630SW IP Telephone with PoE Switch
This Telephone model is powered over network
cabling from a central location using an IEEE 802.3af compliant
switch or power supply as 1151C1/C2 Power Supply.
The use of PoE and local power simultaneously is not supported
and will prevent the adapter from working properly, nor is it intended to
serve as a fail-over option. The power cable must be removed from the
Gigabit adapter to allow for use of PoE.
