Abstract: A modular data center comprises a base electrical module including an uninterruptible power supply (“UPS”) bypass switch, a power connection terminal coupled to the bypass switch, and a UPS power connector, a UPS rack coupled to the base electrical module and configured to house a UPS that receives power from the UPS power connector, and an information technology (“IT”) equipment rack coupled to the base electrical module and configured to house IT equipment that receives power from the base electrical module, the base electrical module being external to the IT equipment rack.

Abstract: A visual trip indicator for a circuit breaker is disclosed. The electronic components of a visual trip indicator are enclosed in a module that attaches to the circuit breaker handle or within pocket defined in the circuit breaker housing. The visual trip indicator includes a light source operated by a state machine which clearly indicates which circuit breaker, of a group of circuit breakers or in a poorly illuminated enclosure, is tripped. The visual trip indicator also indicating, by a coded light signal, the approximate remaining life of an independent power supply powering the visual trip indicator.

Abstract: A modular data center includes a base electrical module having a casing, a controller supported by the casing, and a power distribution unit coupled to the controller. The modular data center further includes an equipment rack having a frame coupled to the base electrical module, with the frame of the equipment rack being configured to receive electronic equipment. The electronic equipment receives power from the base electrical module. The base electrical module is external to the equipment rack.
