CISCO SW 9200 problem with PoE

[JRGC]

Hi everyone,

I have a Cisco Switch 9200Lx48P (Sw version 16.9.3). I have 9 APs connected and working fine and 9 Cameras  with problems. in the begining the cameras were working fine, but suddenly those cameras lost connectivity and now appear as not  connected.

In one moment I had to reload the switch, after that all cameras started to work again but now  this procedure doesn't work. (I know that not is correct)

The PoE capacity is good as you see below :

Additional information :

Hi,

Can you figure out how much power each camera needs and than assign the power to each port statically and test again?

Hi Reza Sharifi

I  configured static power consumed but it doesn't work

Raise a TAC Case and get TAC to confirm/verify if you're hitting CSCvq25360.

The PoE in those ports stopped working, I did some test with another equipment ( Access point ) in the same port and doesn't work anymore only if I connect a computer or another equipment without PoE it work fine.

The Cameras are : Interlogix TruVision 4MP (TVB-5306).

I´ve requested RMA to TAC
