My apologies if this is completely off-topic, but I was hoping someone may be able to point me in the right direction as I don't want to open a TAC unecassarily.
We have an SFP adaptor (GLC-ZK-SM) that was connecting to a CISCO 3825. The adaptor stopped working after a few months use.
I am having a completely terrible time getting the reseller to honour a warranty / RMA fix for the component.
From what I have found directly on CISCO's site, Optical Networking products offer a 5 year limited hardware warranty, so I really don't see what the problem is.
Do I need to try and open a TAC for this?
You can try but typically in my experience the reseller would have needed to register the sale with Cisco for you to be able to open a TAC case and get an RMA put in. If your reseller is giving you a hard time, they may not have been authorized in the first place and probably didn't do this step.
