I had an issue with a couple of 3750 switches connected in stackwise mode. They were providing PoE to many IP phones and Access Points. Also, they were connected to the same RPS.
I had to reboot both switches and after that the PoE of one of the switches stayed in OFF mode. I rebooted both switches one more time but PoE was still unavailable. The "show power inline" command showed status OFF for one switch (the slave). I replaced the slave switch and the issue continued. I connected the switches to a different port in the RPS and that didn't change things.
I had to disconnect the stack cable and created a trunk between both switches in order to make the PoE working again on both switches.
What could be the cause of this? The RPS? Or is there a bug maybe?
Thanks in advance for any input.
