Just some advice on what I would do: First....I like 4.2.32 for arc code. I don't have much experience with code beyond that until we get our v.92 upgrade. But...I would still use the same code on all the arc's. Don't mix arc code when the arc's are installed in the same chassis. Second....I would look and see whether or not nmc chassis awareness is enabled on the questionable arc's as well as the arc's you already having in service. You want to be on the same page as far as that goes. Third....could be possible that there is some sort of bus problems on the chassis's. Seems unlikely though seeing that you have 2 different chassis that this occurs on. Fourth....highlight the nmc that gets the red led and go to performance...failure reasons....what's that say? Hope this helps you out.

I have two spare ARC's, one is 5.2.9 and the other is 5.3.2 If I insert either ARC in either chassis the following will happen: The ARC (viewing via console) will get to "Initializing Flash Device" and pause, then start the "loading Kernel" process over and over, at this point the NMC LED goes red and stays red until I pull the ARC from the chassis. I have a 3rd chassis with just a power supply, no DSP or NMC card in it, if I put either (or both) ARC's in it they will boot fine.
