Would you explain your design a little bit more detailed? Where your Fiber link goes? Where your 1751 router connects? What is your Layer2 and Layer3 topology? What is your traffic? What you want to protect?

Goos luck,

Secondary Link

Do you have any extra fiber pairs? I have a similar setup in my hospitals. I use 2950's in each closet and link the secondary fiber into the fiber ports on the 1st switch off the router. Administratively disable the fiber port on that switch. That handles two remote closets. The third I use a media converter to take the 3rd secondary and convert to copper. When I **** a fiber port I enable the secondary port.
