Sean, All of the nodebus stations on the wire (fibre) for that one node have to use the same NSAP so I am assuming that you are doing all the stations, not just a WP. Your CP's will also need a reboot with the new NSAP. Running with stations on the same nodebus yet different NSAP's can lead to big problems. If you just do the WP and that WP takes over as device monitor master, you can lose all your alarms, even between CP's and WP's using the same NSAP. When a software install is correctly done, the IIF.prm file contains the correct data and you can see the NSAP (or figure them out easily) for all stations including CP's.
