https://community.hpe.com/t5/hpe-eva-storage/msa-1000-switch-error/m-p/4062019#M27055 Hi,<BR /><BR />It looks like something in the switch is faulty... Try removing all the GBICs (SFPs) from the switch and see whether it will get through the POST. If it does, then reinsert the GBICs one at a time and see if you find a faulty one. If it doesn't then the internal port to the MSA might be faulty. In that case you could try reseating the switch in the MSA and see if that resolves the problem. If not then you're probably looking at a replacement switch module...<BR /><BR />Hope this helps,<BR /><BR />Regards,<BR /><BR />Rob Wed, 29 Aug 2007 00:57:55 GMT Rob Leadbeater 2007-08-29T00:57:55Z https://community.hpe.com/t5/hpe-eva-storage/msa-1000-switch-error/m-p/4062018#M27054 MSA 1000 switch readiness led steady yellow.all port leds are steady yellow.no communcation all.we try to log web tool it was stacking. find attachment web access.
