There are 4 floors each with 2 cabinets and upto 150 users per floor.
The idea is to have as much redundancy as possible.  I intend having the 
master portswitch closest to the users.  Is there any issues using both dual 
homed fddi links at the top and redundant repeater links between the cabs. 
What would be the fail over timings of the links.
