Configuring Power over Ethernet Parameters

Power over Ethernet Defaults
The following table lists the defaults for PoE configuration:
Parameter Description
PoE operational status
Total power available to a port
Total power available to an
entire slot
Power priority level for a port
Capacitor detection method
Priority disconnect status
Understanding and Modifying the Default Settings
The sections below provide information on each of the key components within the Power over Ethernet
software. They include information on PoE-related CLI commands. For detailed information on PoE-
related commands, refer to the OmniSwitch CLI Reference Guide.
Note. PoE units support different wattage power supplies. If unlike power supplies are mixed or if an
unsupported power supply (such as a 120W power supply) is used, a console message and a trap are
generated.
PoE Class Detection
Powered devices can be classified into different classes as shown in the table below. Class detection
allows for automatic maximum power adjustment based on the power class detected. This will prevent the
switch from delivering more than the maximum power allowed based on a device's class.
During class detection the switch will allocate the maximum amount of power allowed based on the class
detected. Once powered, if the device uses less than the maximum the remaining power will be made
available for other devices.
