Chapter 2 Installation Procedures

Before Installing the LTO-4 Half-Height Tape Drive

Handling Precautions and Installation Guidelines 2

Always observe the following precautions and guidelines when handling and installing LTO-4 Half-Height Tape Drives:

• Internal, at all times

• Tabletop, when removed from its free-standing enclosure

Handling Precautions

• Internal drives have exposed components that are sensitive to static electricity. To reduce the possibility of damage from static discharge, the drives are packaged in a protective antistatic bag. Do not remove the drive from the antistatic bag until you are ready to install it.

• Wear an ESD-preventive grounding wrist strap or observe similar ESD precautions when working with the drive. Be sure the wrist strap makes good skin contact. Do not remove the wrist strap until you finish working with the drive.

Also, avoid contact between the drive, other equipment, and clothing. The wrist strap only protects the equipment from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Before removing the drive from the antistatic bag, touch a grounded metal surface to discharge any static electricity buildup from your body.

Chapter 2 Installation Procedures

Before Installing the LTO-4 Half-Height Tape Drive

Preinstallation Requirements 2

Handling Precautions (continued)

• Handle the drive by its sides rather than by the top cover to reduce the risk of dropping the drive or damaging it during installation.

• Either lay the drive on a nonconductive surface or put it back inside the protective antistatic bag to reduce the chance of damage from static discharge

Installation Guidelines

Due to the high speed of the LTO-4 HalfHeight Tape Drive, do not connect more than one LTO-4 drive to the same channel on a host SCSI adapter.

Before installing the LTO-4 Half-Height Tape Drive, make sure you have:

• A serial SCSI host bus adapter (HBA) installed and properly configured in the host computer

• Interface components, either:

• 7-pin 1x SATA style interface cable for an internal drive

• 26-pin SFF-8088 mini-SAS style interface cable for a tabletop

drive

• Backup application software that supports the tape drive. For a list of the backup software applications that have been tested with the LTO4 Half-Height Tape Drive, please visit our website at:

Unpacking and Inspecting the Drive 2

www.quantum.com/support

Although each LTO-4 Half-Height Tape Drive is inspected and carefully packaged at the factory, damage can occur:

• In shipment

• When being unpacked
