I've got a Cisco Catalyst 3550 that uses a GBIC Module to connect a fiber connection. We are wanting to replace it with a gigabit switch and we bought a Cisco Small Business SLM2048T-NA switch. It doesn't have the same GBIC module on it however. I've seen that we can buy a Mini-GBIC for our fiber connection, but I don't really know much about fiber connections. We need to figure out what adapter will work for hooking the fiber connection into the new switch. I've attached a pdf that has a picture of the ports on the switches and shows the fiber connection. Any help is greatly appreciated.
