7. Set the disk aside and open the Universal Installation Kit which contains
the installation hardware.
The kit contains two bags. One bag contains the LED lenses, the LED with
the connector cable assembly, and the faceplate. The second bag con-
tains the mounting rails, spacer bar, and a bag of screws needed for
assembly and mounting.
8. Discard the LED lenses and the LED connector cable assembly. These
items are not needed to assemble the hard disk.
9. Assemble the installation kit according to the directions in the box. See Fig-
ure 4-4.
10. Place the mounting rails parallel to each other with the smaller of the two
flanges of the rails on the inside.
11. Assemble the spacer bar and faceplate to form a rectangle using the 6-32 x
3/16 inch screws.
12. Turn the drive over so the circuit side is down.
13. Locate the drive between the rails; the J1, J3 connector end of the drive
unit should be flush with the spacer bar as illustrated in Figure 4-4.
14. Find the two mounting holes on each side of the drive farthest apart. Then,
while holding the 6-32 x 3/16 inch screw with needle nose pliers, start the
screw through the mounting kit rails. Repeat this for the other screw.
15. Tighten the screws while keeping the J1, J3 connector edge of the drive
flush with the spacer bar.
16. Remove the screws holding the spacer bar and discard all 3 items.
