Abstract: An apparatus may include a chassis that can receive a sled and a locking mechanism. The locking mechanism can mechanically lock the sled to the chassis to prevent a sudden power loss that can be caused from an unexpected removal of the sled from the chassis.

The sled may include one or more computing devices that need to be inactive before removing the sled. The apparatus includes a controller that may detect whether at least one of computing devices in the sled are in an active state or in an inactive state. Based on the determination of the state of the computing devices in the sled, the controller may activate the locking mechanism or de-active locking mechanism.

Abstract: In some implementations, a rack management controller can dynamically manage power supply units in a server rack system. For example, the rack management controller can determine how many power supply units should be powered on based on the power requirements of the server rack system. The management controller can configure a power management controller to turn on the determined number of power supply units. The rack management controller can receive status signals from the power supply units in the server rack. The rack management controller can detect when a power supply unit fails based on the status signals. The rack management controller can dynamically reconfigure the power management controller to replace the failed power supply unit by turning on a reserved power supply unit.
