I have no idea what this was. But power distribution in a data center is hierarchical, and as much as you want redundancy, some parts in the chain are very expensive and sometimes you have to turn them off for maintenance.
I never actually worked in a data center, so keep in mind I don’t know what I’m talking about. Traditional DCs have UPS all over the place, but that will only last a finite amount of time, and your maintenance might take longer than the UPS will last.
