3.2.2Cable-select option

Computers that use cable select determine the master and slave drives by selecting or deselecting pin 28, CSEL, on the interface bus. Master and slave drives are determined by their physical position on the cable. To enable cable select, set a jumper as shown in Figure 3. Refer to your computer manual to determine whether your computer supports this option.

3.3Drive mounting

You can mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See Figure 4 for drive mounting dimensions. Follow these important mounting precautions when mount- ing the drive:

•Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling.

•Use only M3 UNC mounting screws.

•Do not overtighten the mounting screws (maximum torque: 4.0 inch-lb).

•Four (4) threads (0.080 inches) minimum screw engagement recommended.
