# 3 Hardware Installation

The installation instructions in this manual address a two module SL150 and a rack with square holes.

## Overview

The base module (Module 1) sits on rails which are secured to the rack with 8-32 screws and mounting blocks. The installation allows sufficient space to expand the library to include a maximum of ten modules. Each module is secured to a vertical rack rail (or stile) with screws and a back rail. The base module connects to each expansion module by a cable. Figure 3-1 shows screws and a clip nut.

4 - Module Flange

5 - Clip Nut

The module accessory package contains parts needed to complete the installation (such as the back rail pieces, screws, clip nuts, and mounting blocks).

After securing the base module in the rack, you can add one or more modules to expand cartridge capacity and increase the number of tape drives. The tape drive assemblies and power supplies are located at the back of a module (see Figure 3-2).

The robot CRU is located at the top of the base module. The robot is locked in the retracted position during shipment (see Figure 3-2). You must reset the robot lock during the initial installation process. To add modules after the initial library installation, you must park the robot and lock it in the shipping position prior to installation of an expansion module.

Each module is identified by a label in the rear, upper–left corner (Module 1 in Figure 3-2). The first expansion module is identified as Module 2 while the ninth expansion module is identified as Module 10. The identification label for an expansion module is attached during the installation process.

## Base Module Mounting Rail

The base module mounting rail consists of two parts (front rail and back rail). The front rail is installed after the back rail.

### Back Rail

Installation of the back rails involves three part types: back rail, mounting block, and an 8–32 screw. A back rail installed on each side of the rack. Figure 3-4 shows the completed installation of the back rail.

Note: The mounting block has two pins and a threaded hole. These elements must reside within a single defined U boundary. Use the scribe marks, notches, or other designations to identify the U boundary. Do not mount the block with the pins straddling a U boundary.

### Tool Requirement

#2 Phillips screwdriver (not provided).

Figure 3-4 Back Rails Installed

### To Install the Base Module Back Rails

Note: An operator in a seated position might need to access the library front control panel and mail slot. Mount the base module at a height that enables easy user access to the front control panel while providing sufficient space for library expansion below the base module (a 10 module library spans 21U).

The following instructions and supporting illustrations use rack units 32 through 34 for installation of the base module while providing access for seated users. The back rail is mounted in the middle rack unit (U 33 for this example).

1. Locate the rack unit designation where you will install the back rail (use the rail installation template as necessary), and allow rack space for library expansion.

2. Position the mounting block so the screw hole is in the second hole (center hole) of the rack unit.

   Note: The pins and screw hole must be within the boundaries of a single rack unit. Pay attention to the rack stile scribe lines or notches which identify the rack unit boundaries.

3. Hold the block in place.

4. Position the back rail so the blade extends to the interior of the rack (see Figure 3-5).

5. Use one hand to hold the back rail and the mounting block in position.

6. Insert the 8–32 screw into the mounting block hole, and turn the screw several full turns by hand.

7. Tighten the 8–32 screw with a #2 Phillips screwdriver.

   Note: If this is a square hole installation, make sure the face of the mounting block is flush with the rack rail. In round hole racks, make sure the pins are within a rack unit and extend an equal distance (see Figure 3-5).

8. Make sure the wide surface of the back rail is plumb with the inside edge of the rack stile while maintaining an equal gap between the rack stile and the top and bottom edges of the back rail.

   Note: The back rails should neither tilt in nor out.

9. Repeat the procedure for the back rail at the identical rack unit on the opposite side of the rack.

   Note: It is critical that the top edges of the back rails are level with each other (see Figure 3-4).

   Figure 3-5 Back Rail Position

### Front Rail

The front rail engages the back rail and is installed from the front of the rack (see Figure 3-6). Installation hardware involves three parts: front rail, mounting block, and an 8–32 screw.

### Tool Requirement

#2 Phillips screwdriver.

### To Install the Front Rail

Task 1 Connect the Front Rail to the Back Rail

  1. Grasp the front rail and position it so the blade is facing into the rack with the rail tabs toward the outside of the rack.

  2. Align the back edge of the front rail with the back rail (see Figure 3-6).

  3. Slide the front rail toward the back rail to engage the front rail tabs.

  4. Push the front rail into the rack until the front edge of the rail is approximately 6 cm (2.4 inches) from the rack stile.

  2 - Front Rail

Task 2 Secure the Front Rail

  1. Position the mounting block behind the rack stile in the second U of the three U span (see Figure 3-7).

     Note: The pins and screw hole must be within the boundaries of a single rack unit. Pay attention to the rack stile scribe lines or notches which identify the rack unit boundaries.

     Tip: You might need to flex the front of the rail away from the rack stile while positioning the mounting block.

  2. Hold the block in position with one hand.

  3. Push the front rail against the rack stile.

  4. Insert the 8–32 screw through the hole in the front rail and thread the screw by hand a few turns into the mounting block.

  5. Tighten the 8–32 screw with a Phillips screwdriver while making sure that the rail is plumb with the inside edge of the rack stile.

     Note: The front rail should not tilt in or tilt out.

  6. Repeat Task 1 and Task 2 for the front rail at the identical rack unit on the opposite side of the rack.

  2 - Second U

  3 - Third U

Task 3 Verify Proper Front Rail Installation

  1. Verify that the rack rails are parallel with each other (installed in the same rack unit positions).

     Note: Do not proceed with the installation unless the rails are parallel. It is critical for the rack rails to be installed parallel with each other (see Figure 3-8).

  2. If your rack has threaded holes, proceed to "Mount the Base Module".

     Figure 3-8 Rails Installed - Front View

### Clip Nut Location

Note: Clip nuts are only used in racks with square holes.

Two screws secure the module to the rack. Racks with square holes use a clip nut and a 10–32 X 5/8 screw. The base module spans 3Us, and the clip nut is installed in the center hole of the lowest (third) rack unit (see Figure 3-9).

Figure 3-9 Clip Nut Location for the Base Module
