: when power supply reaches full load, the switch only gives prompt and
doesn’t supply power to the new one if a new PD is connected to the switch . 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 only gives
prompt that a new PD is connected and doesn’t supply power to it.

1.2.6 Enabling/Disabling the Compatibility Detection of PDs
The compatibility detection of PDs enables an S3026C-PWR to detect those PDs not
complying with 802.3af standard and supply power to them. This function reduces PD
detection rate and the performance of the switch. You are recommended to disable this
function when the PD devices are the ones complying 802.3af standard.
You can enable/disable the compatibility detection of PDs by executing the following
commands.
Perform the following configurations in system view.
