I am facing a problem with a stack of Summit X460-48p switches relating to PoE. The stack is 6 nodes deep and is running XOS 15.0 or 1 from memory. I am not sure of the exact version of the bootrom.
I faced what appears to be a one off situation where the ports (default configured to deliver 15W dropped to 5W) across the stack and the power budget (max usage threshold dropped from 70 to 50%). The problem was not with a specific node but was across the stack.
I am aware of any problems with the power feed. Each of the nodes is provisioned with a single PSU. What I found is that devices that required less than the 5W continued functioning and the stack itself appeared to be normal but devices requring more than 5W obviously would not function.
I am worried if this can be triggered across other stacks running similar code. Once I set the port budget and power limit to the normal it started working and has been stable since. Are there any known issues with PoE as a process.
This is urgent . What could cause this problem. I know that there were issues with PoE with the earlier series of XOS (12 series). Any sugesstions would be appreciated. Thank you.
