3.13 Removing the DSSI Cable from the Enclosure

To remove the DSSI cable from the BA42B Enclosure, follow these steps:
1. Remove the upper and lower drive-mounting shelf combination (refer to

Section 3.11).

2. Disconnect the DSSI cable from the drives on the upper drive-mounting

shelf.

3. Loosen the captive screw that secures the upper drive-mounting shelf to

the lower drive-mounting shelf (refer to Figure 3–33).

4. Lift the left side of the upper drive-mounting shelf and slide it to the

left until the tabs on the right side of the upper drive-mounting shelf are

released from the cutouts in the lower drive-mounting shelf.

5. Disconnect the DSSI cable from the mass storage devices on the upper

drive-mounting shelf.
