TL-SG2428P v4 switch keep dropping PoE ports
2023-03-21 10:57:20
Model: TL-SG2428P  
Hardware Version: V4
Firmware Version: 4.0.5 Build 20221130 Rel.42340

I have a TL-SG2428P v4, latest firmware on all devices and latest virtual Omada controller.  This switch has 2 ports with PoE enabled and these ports will 'go down' randomly.  The only remedy is to reboot the switch.

 

Any advice on what might be causing this?

Hello @Jacko_ ,

 

Did this issue start to happen when you deploy the switch for the first time?

What is the status of the POE light when the port goes down?

Do all POE ports have the same issue?

 

May I know the model number of the PD device?

It is advisable to use different Ethernet cables for the test. The shorter, the better.

  Hi @Hank21

 

Thanks for your reply.

 

No it's just a recent issue, the switch up until now has been fine.

 

When the issue occurs the port goes from green to grey to indicate nothing is attached.  Unplugging and plugging the AP back in doesn't resolve the issue.  All PoE devices have the same issue at the same time when connected to TL-SG2428P, so it seems as though it's a power issue.  I have two other EAP610 APs connected to a Netgear switch which is faultless.

 

Omada Controller v5.9.31 - running on a Windows VM

ER605     v2.0        2.1.2 - connected to the below Netgear PoE switch
TL-SG2428P v4.0        4.0.5
EAP610    v2.0        1.0.2 - connected to Netgear PoE switch (no issue with this one)
EAP610    v2.0        1.0.2 - connected to Netgear PoE switch (no issue with this one)
EAP610    v2.0        1.0.2 - connected via 5 meter pure copper Cat5e run
EAP225-Outdoor     v1.0    5.0.9 - was connected via .5 patch cable
