Disc drive mounting Do not touch the connector pins or any PCB compo- nents without observing static-discharge precautions.
  • Page 36 Hawk 2 Family Installation Guide, Rev. C • 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 0.150 inch (3.81 mm), and 0.20 inch (5.08 mm) into bottom holes, measured from the outer surface of the chassis.
  • Page 37 Hawk 2 Family Installation Guide, Rev. C Do not power up the host system until the drive is mounted and the system cover is replaced. • Connect DC power connector to the drive, except on "NC" model drives which do not have a separate DC power connector.
