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.

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).

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.
Figure 16 A side view of the DBA.
3. Carefully slide the drive out through the
front of the DBA (Figure 17).

screws on each side of the drive.
Figure 18 Sliding the drive in through the front of the DBA.
1. Carefully lower the DBA into the
library while making sure that all
cabling is safely out of the way
(Figure 19).
Caution: It is extremely
important that no
cabling be pinched
under the DBA.
If necessary, enlist the
help of a second
person to hold the
cabling out of the way
while you position the
DBA in place.

Testing the New Drive
1. Reconnect the AC cable and turn on power to the library.
2. After the library initializes, check if a message comes up on the front panel.
• If there is a message, read it and follow any instructions in the listed remedy.
• If there are no messages, proceed to Step 3.
3. Have your host system or backup application perform a short read and write operation.
• This can be done manually on the command line in UNIX or LINUX (tar).
• On Windows, the backup application confirms read and write status.
• If time is an issue, you can use the backup application to identify a single piece of
previously written media. If that identification process completes without error, it confirms
that the drive can read previously written media.
This completes the drive replacement procedure.
