I feel like emergency power-off switches are more for safety than actually reducing the impact of a power failure.

I’m a bit confused about the difference between a power conditioning unit and a redundant power source. I feel like both could play a role.

I remember practicing a question about redundant power sources being crucial for maintaining uptime during failures. That might be the answer.
