Selectively routing signals to data storage devices within a data storage system that includes a movable carriage

A method comprising:

• while a movable carriage is decoupled from a plurality of data storage devices held by a data storage magazine, providing current to the plurality of data storage devices via a set of magazine signal paths of the data storage magazine;
• coupling the movable carriage to the plurality of data storage devices;
• and
• responsive to coupling the movable carriage to the plurality of data storage devices, providing the current to the plurality of data storage devices via a set of carriage signal paths of the movable carriage.

A device comprising:

• a processor;
• a memory comprising instructions that, when executed by the processor, cause the processor to:
• selectively route current to a plurality of data storage devices held by a data storage magazine by:
• routing the current via a set of carriage signal paths of a movable carriage when the movable carriage is coupled to the plurality of data storage devices;
• and
• routing the current via a set of magazine signal paths of the data storage magazine when the movable carriage is not coupled to the plurality of data storage devices.
