Cnmatrix tx2028rf-p POE status

HELLO Gentlemen,

The cnmatrix ports status became suddenly

other fault (26) when applying passive POE.

Noted that the ports connected to pmp 450m AP and were working well.

Thanks in advance.

Hi @Khaled_Shaaban

Could you please share the cnMatrix switch firmware version, and details of the devices connected? Also, on which port are you observing the error, and what device is connected to that port?

Sofrware Version 6.1-r7.

And the fault is on all ports only when I configure POE Passive 54 or 24.

Connected to pmp 450m APs

A few questions regarding your setup:

  1. You are using a 5Ghz 450m. Correct? cnMatrix cannot be used to power up a 3Ghz 450m, as the AP requires too much power - that radio uses a dedicated DC input source.
  2. You mention about configuring the port to “POE Passive 54 or 24”. The 450m can only be powered with 54V. The TX2K has an automatic detect/configure feature which will change the PoE port setting from the default 802.3 mode to the Hybrid 54V mode when a 450m radio is plugged in. Note that you can manually set the port to Hybrid 54V mode instead of utilizing the auto detect/configure feature.
  3. Another key part of your topology is knowing what else you have plugged into the TX2K. You only mention the 450m. Is there any other device connected when you run into the fault condition?

Please raise a support ticket and provide the output of the command “show tech”.
