Using BOOTP, after double-clicking on the MAC Address of the module to be configured, enter the IP Address you wish to assign.
Then after BOOTP has sent the address to the module, click on it again in the relation list, and then click "Disable BootP/DHCP".
If you get a successful response, then the module will be Static IP mode, and should remember the address through a power-cycle. Which can be tested easily, since you're in BOOTP, it won't start broadcasting its MAC Address after rebooting.
I have never had to set thumbwheel to an "illegal" value, just leave it on 999.
I have done this many times, and never had issues.
After doing that, you may, of course, have to set a different SubNet Mask, for which you can use RSLinx.
How the module uses the thumbwheel switch and BOOTP/DHCP enabled or disabled is described on page 5 of the manual
