A method of power management of a multiple-data-storage-devices enclosure is disclosed. In some embodiments, the method includes: receiving a network connection and power from a data connection port detachably coupled to a network cable; identifying a subset of data storage devices within the enclosure to activate; powering off components within the enclosure other than the subset of the data storage devices; for each data storage device in the subset that is not yet powered, activating the data storage device by: monitoring power consumption drawn from the data connection port; identifying a sequence of components associated with the data storage device, wherein the components within the sequence, when powered, together provide access to the data storage device; and powering on each component in the sequence when a previous component in the sequence has reached a steady state power consumption level, wherein when activating the data storage device, power supplied to power on the sequence of the components does not exceed a total power available from the data connection port.
