INSTALLING ATAPE DRIVE IN
This document explains how to install or replace a tape drive in the Tandberg
StorageLibrary T24 or Tandberg StorageLibrary T48. Please read the entire section that
you are using prior to beginning the procedure.
PREPARING FOR INSTALLATION OR REPLACEMENT
Note: If your library is installed in a rack, it is not necessary to remove the library from the
rack to complete this procedure. It is also not necessary to disconnect the Ethernet
cable from the back of the library.
Obtain these items—a #2 Phillips screwdriver and a small flat-blade screwdriver.
Ensure that the environment is free of conditions that could cause electrostatic
discharge (ESD)—If possible, use an antistatic mat and a grounded static protection
wristband during installation. If a mat and wristband are not available, touch a known
grounded surface, such as a computer’s metal chassis.
Warning Before performing any installation or maintenance procedures, be
sure that the library’s power switch is off and that the power cord is
disconnected from the library and the outlet.
Warnung Vor der Ausführung von Installations- oder Wartungsarbeiten ist
darauf zu achten, daß der Library-Netzschalter auf “Aus” gestellt ist
und daß das Anschlußkabel vom Library und der Steckdose entfernt
ist.
Advertencia Antes de realizar cualquier procedimiento de instalación o de
mantenimiento, comprobar que el interruptor de alimentación de la
biblioteca está apagado y que el cable de alimentación no está
enchufado ni a la biblioteca ni a la toma de corriente.

GENERAL INFORMATION
Both the StorageLibrary T24 and StorageLibrary T48 Library accommodate Ultrium 3
(LTO-3) or Ultrium 2 (LTO-2) tape drives in half height (HH) or full height (FH)
configurations. Neither library will accommodate LTO-1 tape drives.
Note: Most of the illustrations show SCSI configurations. Use the same steps to install Fibre
Channel tape drives.
Information that is specific to the individual libraries is indicated as follows:
StorageLibrary T24—One full height tape drive or two half height tape drives
StorageLibrary T48—One or two full height tape drives, or one, two, three, or four half
height tape drives
! Important The tape drives must be specially configured (at the factory) for use in a
StorageLibrary T24 or StorageLibrary T48 library. Purchase tape drive
kits only from Tandberg Data or Tandberg-approved suppliers.

INSTALLING ADDITIONAL TAPE DRIVES
To install an additional tape drive (or tape drives), follow these steps:
1. Preparing for replacement—
a. Power off the library (press the 0on the back of the unit)
b. Disconnect the power cord, the SCSI or Fibre Channel cable(s), and the terminator
(if one is installed).
c. Power off the host
d. Remove the tape drive cover plate (P). Set the plate and the screws aside.
Note: This figure shows the StorageLibrary T24 SCSI library with one half height tape
drive installed. Remove the StorageLibrary T48 tape drive cover plate (SCSI and
Fibre Channel) the same way.
2. Removing the internal cooling plates and disconnecting cables—
Figure 9 Tape drive cover plate (StorageLibrary T24 library shown)
! Important Remove as many internal cooling plates as necessary to add
tape drives, but leave all empty tape drive bays covered. The
plates are required for proper cooling.

4. Completing the installation—
a. Locate the tape drive cover plate (see “Reference Illustrations” on page 3). First,
remove the necessary SCSI plates (S), then attach the tape drive cover plate (P) with
the screws you removed earlier.
b. Reconfigure your library—You must reconfigure your library for your backup
application to recognize the new tape drive. See page 25 for instructions.
! Important The library requires both the SCSI cover plates (S) and the tape
drive cover plates (P) for ESD protection. Do not leave any
openings uncovered.
Do not connect the SCSI cables until after you reconfigure the
library.
