A link-failure test retains the required campus reachability without creating Layer 2 loops. Such an observation would verify a separate issue: The network has two data rooms and the plan provides only one unprotected uplink from each access layer. It would follow the distinct action: Specify redundant uplinks and an appropriate loop-safe high-availability topology for each failure domain. Here the reported failure is An implementation plan budgets enough PoE for average device load but not the concurrent worst-case startup draw. The decisive result for Northpoint Health must instead be: An inventory and startup test stay within the documented total PoE budget and per-port limits.
