I have a 100ST Media converter that I'm connecting to a 3COM 3c17304 Gbic fiber module in port 27. Everything links but DHCP won't work and if I set up my laptop as a static it won't work either. No filtering or mac/ip specific programming is done on the switch according to the IT guy. Fiber Gbic set to auto-negotiating but still no luck.

Any suggestions? Was thinking about getting another MC and using a standard port to start the circuit to use fiber to the other building since they don't want to put out the money for another switch at the other building.

Probably something simple I'm overlooking.

suggestion: change transmit to receive and vice versa on one end.

I didn't think you could use Media converter to GBIC, thought you had to have the same at both ends

According to the manual "The two GBIC ports support Category 5 twisted pair cable and fiber Gigabit Ethernet short-wave (SX), long-wave (LX) and long-haul (LH70) GBIC transceivers in any combination."

If you are using a >100< ST media converter at the other end it's not going to work - either use a gigabit media converter at the far end, or if the remote device only does 100Mb you will have to use another 100Mb media converter plugged into one of the copper ports on the switch.

@nameless - as long as the ethernet standard (100Base-FX, 1000Base-SX, 1000Base-LX being the most common) is the same at both ends and the appropriate fibre (singlemode, or multimode of various grades) is used it doesn't matter what the optical devices are (GBIC, mini-GBIC, SFP, media converter) or what sort of connectors they have (SC, ST, LC being the most common)
