CAUTION:
■ By default, the PoE function on a port is enabled by the default configuration
file 3comoscfg-xxport.def when the device is delivered.
■ If you delete the default configuration file without specifying another one, the
PoE function on a port will be disabled after you restart the device.
Setting the Maximum
Output Power on a Port
The maximum power that can be supplied by each Ethernet electrical port of a
PoE-enabled Switch 4210 to its PD is 15,400 mW. In practice, you can set the
maximum power on a port depending on the actual power of the PD, in the range
of 1,000 to 15,400 mW and in the granularity of 100 mW.
Setting PoE
Management Mode and
PoE Priority of a Port
When a switch is close to its full load in supplying power, you can adjust the
power supply of the switch through the cooperation of the PoE management
mode and the port PoE priority settings. The Switch 4210 supports two PoE
management modes, auto and manual. The auto mode is adopted by default.
■ auto: When the switch is close to its full load in supplying power, it will first
supply power to the PDs that are connected to the ports with critical priority,
and then supply power to the PDs that are connected to the ports with high
