Episode 58 — Power Events: blackout, brownout, surge, spike and protective choices
CloudNetX expects learners to understand how different power events affect infrastructure and what protections are appropriate, because these events create outages that look like “random failures” unless the root cause is recognized. This episode defines blackout as total power loss, brownout as sustained low voltage that can cause unstable device behavior, and surges and spikes as overvoltage conditions that can damage components or trigger protection circuits. The first paragraph focuses on the practical impact on networking gear: blackouts cause abrupt shutdowns, brownouts can cause unpredictable resets and packet loss, and overvoltage events can permanently degrade hardware or power supplies. It also explains the protective layers available, including UPS systems, surge suppression, generator support, and monitoring that alerts operators before failures cascade.
