1.2.4 Setting the Maximum Power on a Power-Feeding Port
Each Ethernet port of an S3026C-PWR can provide a maximum of 15400 milliwatt to
the PDs connected to it. You can adjust this maximum between 0 and 15400 milliwatt
according to the actual power of the PDs.
You can set the maximum power on an ongoing power-feeding port by executing the
following commands.
Perform the following configurations in Ethernet port view.

By default, a port supplies power under a maximum of 15400 milliwatt.
1.2.5 Setting power management mode and Power-Feeding Priority on a Port
An S3026C-PWR as a whole externally provides a total of 160W in extreme. By default,
when reaching this maximum, the S3026C-PWR will not supply any power to any newly
connected PDs.
This command is used with poe priority
of the switch port together. It will be effective
when power supply reaches full load.
auto:
when power supply reaches full load, the switch prefers to supply power to those
PDs connected to a port of a "critical" priority rather than supply power to PDs
connected to a port of a "high" or "low" priority. For example, port A is configured with a
priority of "critical" and is connected to a new PD when the S3026C-PWR supplies
power to the full, then the S3026C-PWR will automatically stop supplying power to any
PD connected to a port of a "low" priority and give the chance to that new PD of port A.
