Got this POST Error yesterday, need some assistance.

I am trying to get a 3560 PoE 24 port switch to run some VoIP sets, and during POST, I got the following error message:
POST:Found inline power controller write failure, inst 4
POST: Inline power test failed

So, am I looking at a hardware failure or a software failure?

If hardware, can a PoE injector be used on the VoIP sets?

Thanks

It seems like it would be hardware to me. Either way, yes an injector will work.

Power Injector for the VoIP sets. It is a hardware failure.

I'm looking at a few switches that have this error on eBay. Is the only thing that is "broken" is the switch cannot provide PoE? If so, that isn't a big deal for me and I could get a few 3560's for a good amount.

Yes, the ports will just not provide power. Unacceptable if the unit is still under smartnet, but still a good piece of lab equipment in my mind if it isn't covered.

So the switch shouldn't have any issues booting up - only providing PoE to the ports? For some reason I thought if a switch fails during POST (no matter what category) it would just stop booting up. As long as I can still access the CLI and the switch functions as normal (minus PoE) then I'm a happy camper.

I just wanted to figure out if my thought process was right or not before I shell out some $.

I have a 3550 with failed inline power running in my lab right now. Works fine, I actually didn't know PoE was broken until I plugged in an AP. After troubleshooting a bit, I showed POST and all 24 ports show failed inline power. Also said inline power failed POST, but its working nonetheless.
