I've got a Cisco Catalyst 3550 that uses a GBIC module to connect another one of the same switches between buildings. This is a picture of the gbic module http://filedb.experts-exchange.com/incoming/2013/09_w39/679236/Front.JPG
We bought a Cisco Small Business SLM2048T-NA to replace it that uses a different module pictured here : http://www.serversupply.com/NETWORKING/TRANSCEIVER/GBIC%20-%20SFP/CISCO/MGBSX1.htm
I used a LC connected cable to connect the new switch, but the switches won't make a connection. My question is, do the switch have to have the same connector/LC Cable to work or can these switches be connected? I posted a question before trying to figure out what GBIC module to buy for the new switch in this topic: http://www.experts-exchange.com/Hardware/Networking_Hardware/Switches/Q_28248325.html
I don't deal with many fiber connections and when I do they are normally already in place and don't have to mess with them.
