7. Turn the rear-bracket thumbscrews to attach the rear brackets to the sides of the
storage enclosure. The screw holes are located about 51 mm (2 in.) from the
rack flange.
Note: To align the thumbscrews with the holes in the unit, you might need to
loosen the screws that attach the rear brackets to the rack cabinet.
8. Tighten all of the M5 screws to secure the rear bracket to the rack cabinet.
9. Continue with “Installing the DDMs.”
Installing the DDMs
Attention:
1. Potential damage to DDMs - Repeatedly turning the power off and on without
waiting for the DDMs to spin down can damage them. Always wait at least 90
seconds from when you turn off the power until you turn it on again.
2. The installation order within each drawer is from left to right in rows. Slots 1,
4, 7, and 10 must have a drive installed in these locations to ensure that there is
sufficient airflow to the drives (see Figure 15 on page 40). To verify these slots,
check the overlay on the front of each of the five drive drawers. Ensure that the
four drives in each row are adjacent to each other. The long edge of each drive
should touch the drive next to it. To maintain a uniform airflow across all drive
drawers, the storage enclosure must be configured with a minimum of 20
drives, with four drives in the front row of each of the five drive drawers.
