A computer cabinet and hot-pluggable disk drive module design including indicator light support for the disk drive module. The cabinet includes a disk drive module receiving bay into which the disk drive module is removably installed. The disk drive receiving bay includes a backplane having at least one connector for engagement with a corresponding connector, preferably a single connector architecture (SCA) connector, protruding from a leading surface of the disk drive module. A light source mounted to the backplane near the backplane connector is illuminated to provide status information concerning the disk drive module. A light conduit extends from the light source to a conspicuous viewing location on the computer cabinet. Multiple indicator lights and corresponding light conduits tinted to different colors may be employed to provide different status indications, e.g., power, activity and fault status information. The light conduits may also be incorporated into the disk drive modules, such that once the disk drive module has been installed within the drive bay the light conduits extend from a location on a leading surface of disk drive tray opposing the light sources contained on the backplane to a conspicuous viewing location on a visible surface of the disk drive module.

Method and apparatus for providing power activity and fault light

The subject invention is a device for joining and separating first and second printed circuit boards connectable by a socket on one of the boards and a plurality of pins projecting from the other of the boards. The device comprises a screw held captive to the first board but rotatable therein, and a spacer fastened to the second board and having a threaded hole for receiving the screw. The pins are inserted into and withdrawn from the socket by the engagement and disengagement, respectively, of the threaded hole by the screw.

Printed circuit board assembly

A high-voltage biological macromolecule transfer and cell fusion system for transforming a low input voltage into a high-voltage discharge output. The system comprises voltages source means, a frequency source means, a burst control means, a cycle control means, a pulse generating means, a pulse control means, and a high-voltage discharge generating means. The voltages source means is adapted to transform the generally low input voltage into a system-enabling control signal, a direct-current base voltage, and a generally low-voltage direct-current system voltage. The frequency source means generates system-enabling control pulses. The burst control means is provided to control the burst time of the high-voltage discharge output. The cycle control means is adapted to control the number of cycles in the high-voltage discharge output. The pulse generating means generates the pulses that evolve into the high-voltage discharge output. The pulse control means is adapted to control the number of pulses within each cycle of the high-voltage discharge output. The burst control means, the cycle control means, the pulse generating means and the pulse control means produce a composite signal. The high-voltage discharge generating means is provided for transforming the low-voltage system voltage and the composite signal into the high-voltage discharge output.
