Hey all,
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?

After a code upgrade and additional testing with a netally linkrunner, it turns out that the board that supplies additional PoE has gone bad. Thanks for ya'lls help.

You should see them in the LLDP command. They need LLDP to negociate power. Does the switch have lldp enabled?

This is a known issue -- CSCvz54607.
Downgrade to 16.12.4.
NOTE: 16.12.4 is toxic to 9300/9400/9500/9600 but it is a "sweet spot" (for the 9200/9200L) in terms of stability.
