3.2 Add-On Disk or Tape Drive Positions

Example 1: Two RA90, one SA72, and two SF72 should be mounted.

• First priority is DSSI. Therefore, mount the two SF72 to positions 1 and 2.

• Second priority is the RA90. Therefore, mount the RA90 to positions 5 and

6. Use the chassis stabilizer brackets.

• Mount the SA72 to position 4.

Example 2: Two SF72, one TF857, two RA92, and one SA70 should be mounted

in the cabinet.

• First priority is DSSI. Therefore, mount the SF72 to positions 1 and 2.

Mount the TF857 tape loader magazine to position 6.

• Second priority is to mount the RA9x to the top or bottom slots. Therefore,

mount the ﬁrst RA92 to position 5. Use the Stabilizer brackets.

• Fill the rest of the open slots with the SDI storage elements. For example,

you might mount the SA70 to position 4 and the second RA92 to position 3.

Example 3: There are two SA72’s mounted to the storage cabinet to positions 1

and 2. The customer would like to add one SF72 storage element.

• First priority is DSSI. Therefore, the SF72 Storage Element should be

mounted to position 1. Remount the SA72 from position 1 and mount the

SF72 to position 1. Another possibility is to mount the ﬁrst SF storage

element in position 4. Nevertheless, cable the ﬁrst DSSI storage element

as SF1 and label it accordingly.

• Mount the second SA72 to position 4 in case you mounted the ﬁrst SF

storage element into Position 1.

1. Upper level disk or tape drive installation

When installing an add-on RA9x storage element to positions 6 or 5 of the

cabinet, it is necessary to remove the cabinet top cover. The drive chassis

stabilizer bracket cannot be removed from the frame and attached to the

upper level disk drive without ﬁrst removing the cabinet top cover. See

Section 3.7.

Each upper level disk or tape drive is supported by two chassis retainer

brackets (top and bottom). Only for the RA90/RA92 you need one chassis

stabilizer bracket, and two (top and bottom) rear lock-down brackets

with one U-clip each. Detailed instructions for removing/installing this

hardware are found in Section 3.12 and in Section 3.17.
