Abstract: A computing device is associated with a circuit for sharing and distributing backup power. During normal operating conditions, a main bus bar provides power to each computing device in a rack via a main power bus of the corresponding circuit. In the event of an AC power outage, the main power bus is deactivated and a backup power path of the circuit is activated. Backup power is provided to the device from a battery of the circuit via the backup power path. A shared power path is also activated in the circuit such that backup power may be provided from the battery to the main bus bar. By providing backup power to the main bus bar, the other computing devices in the rack that do not have sufficient backup power may receive backup power from the main bus bar until AC power is restored.
