Hawk 1LP Family Installation Guide, Rev. D Drive installation This section describes the physical mounting of the drive in the host cabinet and the logical installation as a system member, which is called drive setup. Disc drive mounting Do not touch the connector pins or any PCB compo- nents without observing static-discharge precautions. - Page 35 Hawk 1LP Family Installation Guide, Rev. D • Mount to host system chassis using four 6-32 UNC screws. Three mounting holes are in each side and four in the bottom of the drive. See Figure 4. The maximum length that the screws should extend into the side chassis mounting holes is 0.15 inch (3.81 mm), and 0.20 inch (5.1 mm) into bottom holes, measured from the outer surface of the chassis.
