Hello All,

 

I keep losing my POE connection.  It gives a hearbeat missed message and then goes through the provisioning process.  Throughout the day I continue to receive ""POE Switch on Omada Controller is connected".  I thought it might be wiring buy have changed the cables.  Here's my typical layout. Nothing magical.  Just a SG2008, with an OC200 and ER605 plugged into it, along with an AX5400 and AC1200 meshed together. Typically have some dumb switches from that point on to clients but have eliminated those as well for diagnosis.  

 

I've seen other posts on this but no solutions therefore wondering if someone has figured it out.

 

For reference, here is info on other hardware:

 

ER605 v2.0

Firmware Version:

2.1.2 Build 20230210 Rel.62992

 

Omada Controller_A20793

OC200 1.0 

Firmware Version

1.24.0 Build 20230328 Rel.52384

 

The hardware is all new, out of the box for a week.

 

Thanks,

RP

  @rpaulpen 

 

Hi, are you sure the switch can offer stable power to the OC200? Have you tested by short cables?

Can the switch work fine before? Are these connected logs affecting the actual network?

Just striving to develop myself while helping others.

  @Virgo Hello, thanks for your reply.

 

The OC200 is connected via POE from the switch with a short patch cable.  All the devices are new out of the box therefore I don't have any further history.  As far as affecting work, all the clients disappear from the client list when this happens.  I changed all the cables again yesterday with new cat 6 cables.  I only received the connection messge once over night therefore that's better but still a problem.

@Virgo Here is the log info if helpful.  There is no log entry of it going down but only getting connected twice over night.  The earlier in the evening disconnects were when I switched the cables.

  @rpaulpen There is also a regular heartbeat missed warming on the switch.  Nothing in the logs though.

  @rpaulpen 

 

If these logs don't affect the actual network environment, suggest you may observe for a while if it has lots of logs showing connected.

The frequency of this log is likely to be triggered by deployment setup and other operations, so let's watch it for a few days.

  @Virgo Thanks for your feedback.  It's very frustrating.  What I do know is that hte switch does have quite a few heartbeat misses if I watch the screen.  I think when the switch comes back is what triggers the "connected message"
