I need to install 5 units of 24port Cisco SMI PWR Switch at my clients place. They have also purchased 5 units 1000 Base T GBIC as well. My question here is what is the purpose of that GBIC? and why do they need 5 GBIC for each? It seems they want to use 2 GBIC for each now… I’m quite confused here. Earlier it was supposed to be 1 GBIC for 1 Switch now they want 2 GBIC for 1 Switch…why is that?
