Impact on the System

When an AP works with low power consumption, some component functions such as the USB and PoE out functions are disabled. In addition, radio power is reduced, or radios are disabled. For details, see the functions of APs using different power supply standards in AP Management Configuration GuideManaging the PoE Function of an APUnderstanding PoE in the S2720, S5700, and S6700 V200R019C00 Configuration Guide - WLAN-AC.

Possible Causes

The device that supplies power to the AP does not meet the AP's power supply requirements.

Procedure

Run the lldp enable command in the interface view to enable the LLDP function. In this way, the peer power supply device can identify the power supply standard of the local device and supply power as required.
- If the alarm persists, go to step 2.
- If the alarm is cleared, go to step 4.
Check the peer power supply device and ensure that the power supply standard meets the AP's power supply requirements.
- If the alarm persists, go to step 3.
- If the alarm is cleared, go to step 4.
Collect alarm and configuration information, and contact technical support personnel.
