Post Body

Hey guys, we have 22 Cisco ISR 4331's deployed in our company. It's our primary voice gateway for remote sites that we are using to make our own SD-WAN type environment (MPLS and DMVPN connections back to HQ\DR). Of those 22 4331's I currently have 2 open TAC cases because of hardware failure. The oldest 4331 I have is maybe 2 to 3 years old only.

Does anyone else have hardware failure troubles with their 4331 routers? Just odd to me that I'm at a 9% failure rate on hardware. One was a NIM slot, the other was one of the PS fans.

*EDIT it is not the clock issue with field notice 64253. Just searched all our serials on Cisco site and none were affected* It's not that component that has failed, was a NIM slot and a PS fan, unrelated.
