Not for a CS21/H, but I have the CS11/H tech manual.  I know they're 
contemporary, but presumably different; I have no idea how different. 
The CS11 has four DIP switches:

SW1-1,5,6 set various options
   (expanded silo, interleaving of DM11/DH11 vectors, force 2 stop bits)
SW1-2 is "not used and MUST BE OFF"
SW1-3,4 are used to set DM11/DH11 vectors with SW2
SW2-1...4 set vector address (DM11)
SW2-5...8 set vector address (DH11)
SW3-1 is RUN/HALT-RESET (open/closed)
SW3-2,3 set the number of CP11 panels in use
   (= number of DH11 emulations)
SW3-4 is the override for part of the selftest
SW4-1...4 set start address
SW4-5,6 are "not used and MUST BE OFF"

I don't know how much, if any, help that is.
