Issue
What is the preferred architecture with MNB MSTP controllers when an installation has a MNB-1000 and a Niagara R2 UNC? Hang the controllers on the MSTP bus of the MNB-1000 or the UNC?
Environment
- MNB-1000
- Niagara R2 UNC
- MNB Controllers
Cause
Prevent any performance degradation by hooking up the MNB controllers in the correct location.
Resolution
Either way is OK. If the MNB controllers are on the MSTP trunk under the MNB-1000, then the MNB-1000 acts as a router, and communication is a little slower than if they were directly connected to the UNC.
