Just recently I've been given a Cisco C3548 Switch to look at. This is a shit hot piece of gear. It, like most Cisco enterprise hardware, runs it's own operating system called IOS. Very cool. Unfortunately this one is buggered. It fails POST [Power On Self Test] on the Switch Core ASIC [Application Specific Integrated Circuit], that is what the amber port 6 'of death' means when it goes through POST. More specifically, after reviewing the output when it boots using a console cable, the buffers are shot.
