Spectra 50-Series Library Tape Drive Replacement Guide

Introduction

About This Guide

This guide describes the procedure for replacing a tape drive in the Spectra 50-Series library.

Note: This guide shows pictures of a library that has two full-height drives installed.

The same procedure can be followed for any drive configuration.

Estimated Time Required

This procedure takes about 30 minutes.

Materials and Tools Required

You need a replacement LTO tape drive as shown in Figure 1. Note that the drive needs to be:

• The same type as you already have installed in the library.

• The drive must be already installed in a Spectra 50-Series library drive sled.

You also need:

• A #1 Phillips screwdriver

• An anti-static wrist strap

Preparing the Library

Moving the Carousel

Before you can replace a drive, you must position an empty TeraPack carrier space behind the drive

bay assembly (DBA). This makes it possible to access and remove the DBA.

If your library is fully loaded, you must remove a TeraPack magazine first.

Both these procedures are covered in the following pages; be sure to read them in order.

Before you begin this process, read the following useful information on how magazines and carriers

are numbered inside the library.

•Physical magazine numbers have nothing to do with the logical chambers found in a library

partition.

• Magazines are numbered clockwise.

For example, if Magazine 1 is at the TAP, and you are facing the front of the library, then

Magazine 2 is the next magazine to the left, Magazine 10 is the next magazine to the right, and

Magazine 6 is behind the DBA (see Figure 2).

Using the Run Robotics Utility

9. Once you know which magazine carrier is empty, use the Belt and Door Diagnostics screen to

move the magazine carrier behind the drives.

You accomplish this by moving to the door the magazine that is opposite the empty magazine

carrier; simply calculate the opposite it by adding or subtracting five to or from the empty

magazine number. For example:

• If Magazine 3 is empty, move Magazine 8 to the door.

• If Magazine 6 is empty, move Magazine 1 to the door.

1. Use the library’s front panel to select Maintenance >

Utilities; the Basic Utilities screen appears.

2. Select Show Advanced; a confirmation screen appears.

3. Select Yes; the Advanced Utilities screen appears.

4. Scroll down the list of utilities; find and

select the Run Robotics Utility.

5. Tap Select; a Description screen appears that describes

this utility.

6. Select Run.

A progress screen appears for a few seconds,

then the Robotic Tests screen appears (Figure 3).

7. Select Belt and Door; the Belt and Door

Diagnostics screen appears (Figure 4).

8. If you don’t know which magazine carrier is empty, use

the Belt and Door Diagnostics screen to move each

magazine to the door, and open and close the door to

check if you have selected an empty one.

If there are no empty magazines, open the door and

remove one, then close the door.

Removing the Library Cover

1. Turn off power to the library.

2. Put an anti-static strap on your wrist and connect it to the back of the library.

Caution: If you do not wear an anti-static strap, any damage caused to the library by

static will not be covered by the library’s warranty.

5. Pull the cover back (Figure 6), and finally up (Figure 7).

6. Place the cover in a safe place; do not set anything on top of the cover.

7. Proceed to Removing the Old Drive on page 8.

3. Remove the seven Phillips screws from

the library cover (Figure 5).

• Four screws in the top center of

the cover.

• Three screws on the rear of the

cover.

4. Lift the rear of the cover up slightly to

loosen it from the chassis.

Removing the Old Drive

Removing the DBA from the Library

1. Disconnect the fan cable(s) from the

drive interface board (DIB).

The fan cables are yellow, red, and black,

and they are plugged into the top of the

DIB (Figure 8).

Figure 8 The fan cables plugged into the board.

2. Pinch the tabs on the sides of the fan(s)

to slide the fan(s) gently upward and out

of the DBA (Figure 9).

Figure 9 Removing the fans from the library.

3. Disconnect the drive power and

communication cables from the DIB.

The drive power and communication

cables are black cables shrinkwrapped in

green sheathing and plugged into the top

of the DIB (Figure 10).

Figure 10 The drive communication and power cables plugged into the board.

4. Disconnect the SCSI or Fibre Channel cable(s)

from the drive(s).

SCSI cables are flat and white (shown in

Figure 11). Remove them by holding the sides

of the connector and gently pulling outward.

Fibre Channel cables are thin and orange.

Remove them by pinching the top and bottom

of the connector, then gently pulling outward.

Figure 11 The SCSI cables.

5. Loosen the two thumbscrews located near the

back of the DBA (Figure 12).

Figure 12 The thumbscrews as seen from above.

6. Slide the DBA back, toward the rear of the

library, until the base of the DBA is clear of the

captive pin (Figure 13).

Figure 13 The captive pin.

7. Lift the DBA up and out of the library (Figure 14)

and place it on a flat work surface.

Removing the Drive from the DBA

1. Unplug the drive that needs to be replaced from the DIB.

• Drives in a Spectra 50-Series library are numbered from the bottom up.

• If you have a library with full-height (FH) drives, the bottom drive

is Drive 1, and the top drive is Drive 2. They are plugged into the

DIB in ports 1A and 2A respectively.

• If you have a library with half-height (HH) drives, they are

numbered from Drive 1A at the bottom to Drive 2B at the top.

• Figure 15 at right shows the drive interface portion of the DIB.

It shows how drives in the library are installed from the bottom up.

2. Remove the screws for the drive you

want to replace (Figure 16).

There are two screws on each side of the

DBA.

3. Carefully slide the drive out through the

front of the DBA (Figure 17).
