Systems, methods and apparatus are provided through which in some implementations a wired switch or sensor with a mounting system is mounted on a holster and is interfaced either electrically or through a radio transmitter to the radio in order to trip a panic button. The optical-fiber-drawing axis of the preform is aligned with the force of gravity. A logical unit of storage is implemented at each storage location such that each implemented LUN comprises a substantially complete replica of the data stored in each other LUN.
