I recently noticed the PoE LED on one of my VoIP switches was blinking amber rapidly. I switched the LED display mode to PoE, and a cluster of 4 ports were blinking amber - these ports were not even being used. I looked up the PoE status for those ports in the CLI and it was listed as "faulty".
I attempted to shutdown and restart the ports, disable and re-enable PoE on the ports, and rebooted the switch several times to no avail. Remember, nothing is attached to these 4 ports.
Other ports with phones connected seem to work fine. The switch response over telnet seems slower than usual.
Does the switch need to be replaced?
