I have 3 cisco switches in 3 closets in the same building. the 6509 has 2 sup720 cards. the 6506 switches each have a sup. 32 card. i plan to interconnect with fiber. should the fiber go from the sp 720 to each 6506 sup card? the 6509 has fiber on slot1/1-4. the 6506 switches only have fiber connectors on the sup32 cards.
