We have a problem switch (Adtran Netvanta 1544P) that is currently plugged into our network stack. It connects back to our main switch. Recently, this problem switch has created an issue where it will bring down traffic going into the main switch. There are only about 20 active connections on the problem switch that are also POE. When the issue arises we are unable to ping main switch in the facility. Disconnecting or rebooting the problem switch will return everything to normal. It will run fine for a few hours then repeat this pattern. There are no new connections into the problem switch and has worked fine for the last 5 years.
The only thing that I can see is that the chassis fans seem to operating at 92% consistently and the POE CPU temperature is running at 102 F. I'm unable to see a flood of data into the switch.
Thanks
