Traditional installation schemes don’t meet the requirements of business network closets today. And single-corded IT equipment, which only allow for a single UPS or PDU to be connected, represents a single point of failure.
Moving beyond traditional installation schemes, a maintenance bypass or automatic transfer switch (ATS) can dramatically improve system reliability without incurring the cost of adding another UPS.
With a maintenance bypass (MBP), utility power runs through the MBP via the UPS and then to the PDU and out to the rest of the equipment in the rack. Should the UPS need to be replaced, the power can be switched away from the UPS without having to shut down your equipment.
