According to at least one aspect, embodiments herein provide a traffic light power management system comprising a power source, a first output, a service bypass unit and a power management unit. The service bypass unit is configured to receive AC power from the power source, convert the AC power to a first DC power in a first mode of operation, provide the first DC power to the first output in the first mode of operation, and provide the AC power to a power management unit in a second mode of operation. The power management unit is coupled to the service bypass unit, and is configured to receive the AC power from the service bypass unit in the second mode of operation, convert the AC power to a second DC power in the second mode of operation, and provide the DC power to the first output in the second mode of operation.

An air removal unit configured for removing exhaust air from an equipment rack or enclosure includes multiple fans to achieve a high airflow capacity while defining a compact and portable structure. The unit removably installs along an exhaust side of an equipment rack or enclosure to provide capabilities for managing the thermal output of equipment, such as servers, CPUs, communications, internetworking and other types of equipment. The unit includes one or more upper fan modules and one or more lower fan modules positioned below the upper fan modules. The upper and the lower fan modules are arranged in a stacked configuration along the depth of the unit with the lower fan modules positioned in an offset orientation relative to the upper fan modules. The stacked configuration and the offset orientation of the fan modules help to incorporate multiple fans with the unit while maintaining the compact and portable design. The unit is further configured to serve as a door of an equipment rack or enclosure to thereby provide access to the unit and the rack or enclosure during operation. The unit can be incorporated with a ventilation system or a cooling air system associated with an equipment room or data center.

An uninterruptible power supply (UPS) is provided that can alleviate difficulties in shipping electronic devices containing batteries, such as UPS devices by providing a battery connect/disconnect assembly that can connect and disconnect an internal battery from outside the chassis of the UPS. The UPS comprises an input, output, DC voltage source, electrical circuit, chassis, and connect/disconnect assembly. The input receives input power from an input power source, and the output provides output power to a load. The DC voltage source provides DC power and has first and second terminals. The electrical circuit is operably coupled to the DC voltage source and is capable of receiving the input power and providing the output power. The chassis houses at least the DC voltage source and the electrical circuit. The connect/disconnect assembly is operably coupled to the DC voltage source and is constructed and arranged to be operable from outside the chassis. The connect/disconnect assembly has a first state wherein the DC voltage source is operably coupled to the electrical circuit and a second state wherein the DC voltage source is operably disconnected from the electrical circuit.
