I have a ethernet over fiber network. I am attempting to cascade two switches -- Other than the crossover cable (RJ45) How would I connect the two switches via the fiber ports? My first thought was to connect the tx of sw 1 to the rx of sw 2 and the tx of sw 2 back to the fiber patch -- but is this workable -- AND, if it is, how do I treat IP addresses for each switch, delete one and keep one.

It's mostly depends on what brand and models your switches are. For example, in Cisco switches you should use Fiber Optic modules (GBIC). Some another switches have embedded Fiber Optics connectors. You should read swich documentation what it says about Fiber to use (MultiMode or SingleMode), allowed distance (short distance or long distance). If it's simply "workgroup" switches, most likely they have Short Distance MultiMode interfaces. So, just connect TX<-->RX. Another thing to consider - ifit's managed switches and you have VLANs configured, probably you will need to configure ports, which connects switches as "trunk ports". But if you have pure flat network, you don't need to do that. And last thing, if you configure all your switches with IP addresses and those IP addresses are in same network with your workstation, you will be able to access them individually.

Good luck.
