Usage Guidelines

Usage Scenario

Switches that comply with 802.3at or 802.3bt cannot power some non-standard PDs that do not support inrush current. To power these PDs, configure the power supply standards of interfaces as 802.3af.

Precautions

The poe af-inrush enable command applies to the scenario where some non-standard PDs cannot be powered on. After this command is executed, some PDs requiring high current may be unable to be powered on.
After running the poe af-inrush enable command, remove non-standard PDs and then install them so that they can be powered on.
On the S5720-16X-PWH-LI-AC, S5720-28X-PWH-LI-AC, S5720I-SI, S5735-L, S5735S-L, S5735S-L-M, S5735-S, S5735-S-I, S5730-HI, S5730-SI, S5730S-EI, S5731-H, S5731-S, S5731S-S, S5732-H, and S6720-SI, the poe af-inrush enable and poe single-class enable commands are mutually exclusive and cannot be configured on the same interface.
In an upgrade to V200R011C10 or later, if the poe af-inrush enable command is configured in the system view before the upgrade, the poe af-inrush enable command configuration is automatically generated on all interfaces after the upgrade.
