Caution:
z
By default, the PoE function on a port is enabled by the default configuration file
(config.def) when the device is delivered.
z
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.
1.2.3 Setting the Maximum Output Power on a Port
The maximum power that can be supplied by each Ethernet electrical port of a
PoE-enabled S5600 switch 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.
Follow these steps to set the maximum output power on a port:

1.2.4 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. S5600 series switches support 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 priority. For
example: Port A has the priority of critical. When the switch PoE is close to its full
load and a new PD is now added to port A, the switch will power down the PD
connected to the port with the lowest priority and turn to supply power to this new
PD. If more than one port has the same lowest priority, the switch will power down
the PD connected to the port with larger port number.

: When the switch is close to its full load in supplying power, it will not
make change to its original power supply status based on its priority when a new
PD is added. For example: Port A has the priority critical. When the switch PoE is
