3.12 Installing Cabinet Hardware

After removing the bezel, half bezel, OCP, and cabinet rear panel, prepare the

cabinet hardware for storage element installation as follows:

1. Remove the two clear plastic grille mounting brackets. The brackets are

designated as left-hand (part number 74–37919–02) and right-hand (part

number 74–37919–01). Each bracket is secured with two 10-32 x 5/8

pan-head Phillips sems screws. Save these brackets and screws.

Note

A nylon washer is located in the hardware stack-up of the bottom hole

of the clear plastic grille mounting bracket. The nylon washer resides

between the grille mounting bracket and the cabinet frame. The nylon

washer maintains spacing for bezel alignment until the add-on disk

or tape drive retainer bracket is installed. The nylon washer can be

discarded after the storage element installation.

Be sure to reinstall these plastic grille mounting brackets after placing

the add-on storage element into the cabinet. See Section 3.17.

2. If installing an upper-level storage element, remove the cabinet top cover.

See Section 3.7.

Note

Only for the RA90/RA92 disk drive.

• Remove the two 10-32 x 5/8 hex serrated screws of the associated

cabinet stabilizer bracket from the cabinet frame.

• Attach the cabinet stabilizer bracket to the top of the add-on disk drive

with two 10/32 x 7/16 ﬂat-head Phillips screws (from the plastic bag

that came with the RA90–NA/RA92–NA disk drive add-on kit).

The chassis stabilizer bracket position corresponds to the disk drive

position and level the disk drive will occupy. The chassis stabilizer

brackets for disk drive positions 5 and 6 attach to the cabinet frame

crossbar above the disk drives. The chassis stabilizer brackets for disk

drive positions 1 and 2 attach to the cabinet frame crossbar below

the disk drives. Disk drive positions 3 and 4 do not require chassis

stabilizer brackets.
