A technician is installing a new server with redundant power supplies in an ISO-certified datacenter. Which of the following should the technician perform?

Determining maximum power load is important for capacity planning but does not address how the redundant supplies are connected or whether true circuit-level redundancy exists.

Connecting each redundant power supply to an independent circuit ensures that a circuit breaker trip, PDU failure, or wiring fault on one path does not simultaneously remove power from both supplies. This is a fundamental data center best practice and a requirement in ISO-certified facilities to achieve genuine power path redundancy. Without circuit separation, the redundant PSUs share a single point of failure upstream.

Connecting both PSUs to the same UPS creates a single point of failure at the UPS device - if that UPS fails, both power paths are lost simultaneously.

Running a drop cord from an unused outlet is an unsafe and non-compliant method that violates ISO datacenter standards and proper power delivery requirements.
