networking A4924-60001 1000base SX fibre

Greetings all,

I have this HSC fibre card (A4924-60001) in a kbox running 11.o. What I would like to know is this: should i be getting a link LED on the card when a physical connection exists? or should I only get a link once everything is patched up and drivers loaded. Also, can I connect this 1000 base fibre card to a 100base switch? Is it a REQUIREMENT to go from 1000base -> 1000base?
(when what is a switch for?) I have a cisco catalyst 2900 with optional dual port 100base fibre card installed, i go from the k into to cisco, and no link. I can plug each end of the fibre cable in the cisco and get a link that way, just to make sure the LEDS are working. Do you need to set topology with fibre networking? private loop, arbitrated loop, public loop etc? With ethernet you get a link led when there is a physical connection no matter if there are drivers controlling your card or not, not true with fibre? I've packed a lunch, someone take me to school on this one please!
