Maximum Port Power
There are six possible operating modes where the Juice Box will output power to a load. These
are:
•
802.3af Class 0
•
802.3af Class 1
•
802.3af Class 2
•
802.3af Class 3
•
Legacy
•
Forced ON
The maximum port power for Class 1, 2, and 3 is defined by the 802.3af specification as 4, 7,
and 15.4 watts respectively. For 802.3af Class 0, Legacy, and Forced ON modes, the maximum
port power can be set between 1 and 15 watts in 1 watt increments. If a load draws up to 1 watt
over the allocated power the system will respond with an OVER-POWER warning in the port
status information. If the load draws more than 1 watt over the allocated power, the system will
disconnect the load and indicate a POWER FAULT condition.
The port configuration can be changed using either the WEB Interface or the Serial Interface.
