Engineering Guidelines
108
Some MiVoice IP Phones do not support the optional classification feature, and the PSE
connection defaults to Class 0 (15.4 Watts for the IP Phones, which is more than they require).
Some Ethernet switches can run into problems as they cannot supply 15.4 Watts to all ports
simultaneously, so the Ethernet switch specifications should be considered prior to deploying
phones.
LLDP-MED power advertisements
Table 36 can be used to determine which LLDP-MED power advertisement a phone will use.

See Note 2.
Note 1:
See “Power Restrictions” on page 68. for information about power restrictions related to the Gigabit
Ethernet Phone Stand.
Note 2:
The UC360 is an IEEE 802.3at (Type 2) Class 4 device. IEEE 802.3at (Type 2) Class 4 devices draw
from 12.95 Watts to 25.5 Watts.
Note:
It should be noted that the IEEE 802.3af Classes for advertising power
requirements are very granular, for instance Class 1 covers a range of 4 watts. Class
ranges are indicated below.
• Class 0 is the default Class. Devices that do not support the optional classification will default
to this setting. Class 0 requests the PSE to provide 15.4 Watts of power.
• Class 1 requests the PSE to provide from 0 to 4 Watts.
• Class 2 requests the PSE to provide from 4 to 7 Watts.
• Class 3 requests the PSE to provide from 7 to 15.4 Watts (like Class 0); however, the PD will
always draw at least 7 Watts or more.
