Avaya 5600 Series - Manual (Page 8)

Figure 2 Powering Option for 4602SW, 5602SW, 4602SW+, 5602SW+, 4610SW, 5610SW IP phones
Note:
These Telephone models are 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.
---=optional Representative drawing - not to scale. Exact Jack
positions and orientations vary between specific models.
