This section describes whether a PoE switch can supply power to APs connected to the switch. For details about how to configure APs, see the manual of the specific AP model.
Principles
Cause | Configuration to Be Performed on a PoE Switch |
|---|---|
The PD detection signature capacitance is larger than 0.15 uF. | Run the poe legacy enable command on the interfaces that connect the switch to PDs to enable PD compatibility check. |
The current of PDs cannot exceed 10 mA for more than 75 ms within every 325 ms after the PDs are powered on. | Run the poe power-on delay delay-time command on the interfaces that connect the switch to PDs to set the power-on delay. By default, the power-on delay of interfaces is 0. That is, power-on is not delayed. |
The current for a specific PD class is larger than 51 mA. | Run the poe force-power command on the interfaces that connect the switch to PDs to forcibly provide power to the PDs. |

Cisco AIR-CAP1602I-A-K9, Cisco AIR-CAP3702I-H-K9, Cisco AIR-CAP2602I-A-K9, CiscoAIR-CAP1131AG-C-K9, Cisco AIR-CAP3602I-A-K9, Cisco AIR-CAP1702I-C-K9, Cisco AIR-AP1852I-H-K9, Cisco AIR-AP3802E-H-K9, Cisco AIR-AP1852I-H-K9, Cisco AIR-AP3802E-H-K9, Aruba AP205, Meraki MR34, Ruijie RG-AP130, Huawei R230D, Huawei R240D, HuaweiAP2030DN, Huawei WA603, Huawei AP6050DN, Huawei AP7050DN-E, HuaweiAP7050DE, Huawei AP4030DN, Huawei BTS3911B, Huawei AP5030DN, HuaweiAP9430DN-12, Huawei AP5130DN, Huawei AP7050DN-E, Huawei AP7110DN, Huawei AP8130DN, TP-link TL-AP300C-POE, TP-Link TL-AP452C-POE, TP-Link TL-AP1750C-POE, TP-link TL-AP300C-POE, TP-Link TL-AP452C-POE, TP-Link TL-AP1750C-POE, Ruckus ZoneFlex R710, Ruckus ZoneFlex R610, Ruckus ZoneFlex R510, Ruckus ZoneFlex R710, Ruckus ZoneFlexR610, Ruckus ZoneFlex R510 | Standard PDs | Yes | None |
Aruba AP 325, MikroTik | Nonstandard PDs | No | Cause: The cable pairs 4/5 and 7/8 of the AP has backfeed voltage, causing the cable pairs 4/5 and 7/8 of the three adjacent ports of the port connected to the AP carry power. Solution: Use an isolation header to power on these PDs. For details about isolation headers, contact product maintenance personnel. |
Netgear WG102-500 | Nonstandard PDs | No | Use PoE switches developed in versions later than V200R008. |
Aastra 6725, Ruijie RG-AP520 | Nonstandard PDs | No | Cause: The current of PDs cannot exceed 10 mA for more than 75 ms within every 325 ms after the PDs are powered on. Solution: Run the poe power-on delaydelay-time command on the interfaces that connect the switch to PDs to set the power-on delay. By default, the power-on delay of interfaces is 0. That is, power-on is not delayed. |
