Hi, new to the forum and mac as well. Here is my issue, I have the following hardware: Linksys EtherFast Cable/DSL Router with 4-Port 10/100 Switch (BEFSR41) Linksys EZXS88W EtherFast 10/100 8-Port Workgroup Switches (Two of them) I'm trying to Network 12 IMacs (OS X) with the above hardware. Here is what I have so far. I have connected to each Ethernet port a CAT5 cable from the 'built in' Ethernet port into the number ports on the switch. (1-8) In order to connect the two switches I have used a 'Crossover cable' and that is in the 'Uplink' port of the switch. I get steady green lights on the first two rows. Then all orange/amber lights which would detect an 'collison(s). On the switches. I have also used a straight through to connect to one switch into the back of the router port and the Internet port has a CAT5 coming from an existing DSL connection. The CD will not run since .exe files are for PCs. And I cannot even get to the router's config page to configure it to get this network off the ground. So, in summary how what the correct configs as far as cables into what ports and do I even need a crossover cable to connect both switches? Please any help would be gladly appreciated!!
