Orientation ----------- We recommend orienting the drive or directing the air flow in a way that creates the least amount of air-flow resistance while providing air flow above the circuit boards and around the head and disc assembly (HDA). Also, choose the shortest possible path between the air inlet and exit. This minimizes the distance traveled by air that is heated by the drive and by other nearby heat sources. The air-flow patterns can be created by the fans either pushing or drawing air. The overall flow pattern can be directed from front to back, back to front, or side to side. Mounting the drive and connecting cables ---------------------------------------- Do not touch the connector pins or any components on the control board without observing static-discharge precautions. Always handle the drive by the frame only. The drive may be mounted in any orientation (horizontally, vertically, and any combination thereof); however, you must ensure that the drive receives adequate air flow for cooling. 1. Mount the drive to the host system's chassis using four 6-32 UNC screws. Two mounting holes are in each side of the HDA and there are four mounting holes in the bottom of the HDA. The maximum length that the screws should extend into the HDA mounting holes is 0.17 inch (4.318 mm), measured from the outer surface of the HDA. Tighten the screws down evenly. Do not over-tighten or force the screw if it does not seem to screw in easily, because this means the threads are not properly aligned. In this case, back the screw out and try again. 2. Verify that all connections between the drive and the host system are correctly installed. 3. Verify that you have correctly installed jumpers. 4. Connect the SCSI cable into the drive's SCSI connector. Take care not to stretch or crimp this cable, and do not block the system's cooling air flow with the cable. The drive receives DC power through a 4-pin connector mounted next to the SCSI connector. The output of a power supply must meet SELV (safety extra low voltage) as defined in IEC 950. To connect the DC power cable to the drive, simply insert the cable end into the drive's DC power connector. Note. Signal ground on the printed circuit board assembly (PCB) and the head and disc assembly (HDA) are connected together in this drive and you cannot separate them. Ensure the equipment in which you have mounted the drive is connected directly to the HDA. Maximizing the conductive contact area between HDA ground and system ground may reduce radiated emissions. If you do not want the system chassis to be connected to the HDA/PCB ground, you must provide a nonconductive (electrically isolating) method of mounting the drive in the host system. This may increase radiated emissions and is the system designer's responsibility. 5. Replace the host system's cover. ********************************************************************** G E N E R A L ********************************************************************** NEVER Announced but never produced.
