I'm stuck on this one. I have a C9200L-24P-4X running version 16.12.4 with 2 PCs and 2 VoIP phones - Avaya. Since Friday, the 2 phones won't power on, nothing at all. Originally I thought ok they might've gotten fried somehow. I had our voip tech go out and replace the 2 phones and the new ones won't power on either.
Nothing has changed on the L2/L3 switch. Configuration is still the same. The 2 PCs work fine. I have my power set to auto on the switch. Anyone have any suggestions or seen anything like this?
