6.3 Applications

This section describes applications of the PoE feature.
Terminals such as IP phones, cameras, and data collectors require DC power. These terminals
are usually installed in corridors or on the ceilings where power sockets are unavailable. On
most large-scale LANs, administrators manage many access point devices that require
centralized power supply; therefore, power supply management is difficult.
As shown in
devices, such as IP phones and cameras. The PoE function reduces power cables, saves network
construction costs, and facilitates access device management because external power supplies
are not required.

Field
Power Type
Power value: contains PD requested power value and PSE allocated power value. When
the PoE power is sufficient, the two values are the same. The value is an integer that ranges
from 1 to 255. Exchange power = 0.1 x Hexadecimal value of the field. For example, if the
value of the field is 255, the exchange power is 25.5 W.
