I'm doing a network upgrade and installing Cisco 2960x switches. I'm trying to use the 10GB SPF+ ports running over MulitMode fiber. I can't figure out why I can't get the SFP+ modules to link up. The distance is not more then 500' I know the fiber pairs work because the existing switches work over those same pairs.
Any help would be appreciated.
Thanks
