I am planning on using an 1841 configured as terminal server in each closet with 1-2 HWIC-8A slots in each router depending on the number of lines that I need for the devices in that closet. I am going to be linking them all 1841s in each closet together with 8 port 2960s or reused 2950 series switches coresident. These 2960/2950s will all be home runned over fiber back to a core for the out of band network.  Some of the closets in the design are uplinked into distribution layer closets over Cat5e cable. Nothing exceeds 300 ft, however, I am not sure how far I can stretch these Async lines to the console ports from the distribution to access layer switches. Does anyone know how far I can go with an RS-232 line over Cat5e? All I need is 9600 baud to talk to the console port at the other end.

You could also pick up a pair of RS422 converters. The downside is
additional cost, however, it could be a wash if you end up needing
expensive cable to do long 232 runs.
