2. Place shipping containers on a flat, clean, stable surface; then carefully remove the contents. If

the equipment is damaged, notify your Certance representative.

3. Always save the containers and packing materials for any future reshipment.

Internal Tape Drive Guidelines and Cautions

The following guidelines and cautions apply to handling and installing internal tape drives. Keep them in mind as you install the drive.

• Handle the drive by the sides rather than by the top cover to reduce the risk of dropping the

drive or damaging it during installation.

• Internal drives contain some exposed components that are sensitive to static electricity. To

reduce the possibility of damage from static discharge, the drives are shipped in a protective antistatic bag. Do not remove the drive from the antistatic bag until you are ready to install it.

• Before you remove the drive from the antistatic bag, touch a metal or grounded surface to dis-

charge any static electricity buildup from your body.

Installation (and Quick Start) Drive Installation Instructions

• Always lay the drive either on top of the antistatic bag or place it inside of the bag to reduce

the chance of damage from static discharge.

• Install HVD drives only in an HVD environment, Fibre Channel drives only in a Fibre Channel

environment, and LVD drives only in an LVD environment. Do not mix HVD and LVD devices on the same SCSI bus. Look at the label above the drive’s SCSI connector to determine whether the drive is an HVD or an LVD model (see

Figure 2 on page 16):

DIFF

Fibre Channel

• Due to the speed of the LTO-2 drive, it is recommended that a maximum of one LTO-2 drive be

connected to one host SCSI adapter. In a switched Fibre Channel environment, the maximum number of drives that can be used simultaneously depends on the bandwidth of the loop.

Drive Installation Instructions

After unpacking and inspecting your shipping containers and reviewing the installation guidelines and cautions, proceed to the appropriate section in this chapter for instructions on installing your LTO-1 or LTO-2 tape drive.

• If you have an internal LTO-1 or LTO-2 tape drive, go to “Installing an Internal LTO-1 or LTO-2

Drive” on page 16.

• If you have an internal LTO-1 Fibre Channel tape drive, go to “Installing an Internal LTO-1

Fibre Channel Drive” on page 23.

• If you have a desktop LTO-1 or LTO-2 tape drive, go to “Installing a Desktop Drive” on

page 28.

Installing an Internal LTO-1 or LTO-2 Drive

Installing an internal LTO-1 or LTO-2 tape drive with an Ultra2 SCSI LVD or Ultra SCSI HVD interface involves the following steps:

1. “Configuring an HVD or LVD Drive” on page 17

2. “Mounting an Internal HVD or LVD Drive” on page 19

Installation (and Quick Start) Installing an Internal LTO-1 or LTO-2 Drive

Configuring an HVD or LVD Drive

Before you install the HVD or LVD tape drive in your computer, you may need to configure the drive’s SCSI ID and terminator power features. The default configuration settings for the LTO-1 and LTO-2 drives are:

• SCSI ID: 6

• Terminator power: disabled

If you need to change these settings, refer to the following sections. Otherwise, skip to “Mounting an Internal HVD or LVD Drive” on page 19.

SCSI ID

Jumper Pins: 1–2, 3–4, 5–6, 7–8

Default Setting: SCSI ID 6

Each SCSI device on the bus must have its own unique SCSI ID. The internal tape drive is shipped with a default SCSI ID of 6. If another SCSI device in the SCSI chain is using this ID, use jumper pins 1–2, 3–4, 5–6, and 7–8 to change the SCSI ID of the LTO-1 or LTO-2 drive (see

page 17 and Table 1 on page 18), or assign a unique SCSI ID to the other SCSI device.

NOTE: The SCSI controller or host adapter generally uses ID 7. In some systems, the boot drive uses ID 0 or ID 1. Avoid setting your drive’s SCSI ID to these settings.

Terminator Power

By default, terminator power is disabled on internal LTO-1 and LTO-2 tape drives. To enable terminator power, place a jumper across pins 11 and 12.

NOTE: The internal LTO-1 and LTO-2 drives do not provide SCSI termination. Thus, a terminator must be installed on the drive if it is the last device in a SCSI chain.

Installation (and Quick Start) Installing an Internal LTO-1 or LTO-2 Drive

Mounting an Internal HVD or LVD Drive

You can mount the internal LTO-1 and LTO-2 drives either horizontally or vertically, with the drives left side facing up (see

• If you mount the drive vertically, the left side of the drive must face up and the side of the drive

should be within 5 degrees of horizontal.

• If you mount the drive horizontally, the base of the drive must be within 15 degrees of horizon-

tal and the PCB side of the drive must face down.

Figure 4. Acceptable Mounting Orientations

Mount the drive in a 5.25-inch, full-height drive bay and secure it using two M3.0 X 5 metric screws on each side of the drive. Do not use screws longer than 5 mm or you may damage the drive. Figure 5 on page 19 shows the locations of the mounting-screw holes on the side and bottom of the drive, respectively.

Figure 4 on page 19).

Figure 5. Internal LTO-1 and LTO-2 Drive Mounting Dimensions

Installation (and Quick Start) Installing an Internal LTO-1 or LTO-2 Drive

Connecting a SCSI Cable

The internal LTO-1 and LTO-2 drives have an Ultra2 SCSI interface, terminated by either a 68-pin HVD or LVD SCSI connector. Use the following procedure to connect a SCSI cable to this connector.

1. Turn off all power to the drive and the computer.

2. Attach the SCSI interface cable to the 68-pin SCSI interface connector on the back of the drive

(see

Figure 6 on page 20).

CAUTION: Install an HVD drive only in an HVD environment and an LVD drive only in an LVD environment. Look at the label above the drive’s SCSI connector to determine if the drive is an HVD or an LVD model (see Figure 2 on page 16). Plugging an HVD drive into an LVD bus, or vice versa, makes the entire bus non-functional and may permanently damage the drive or other SCSI devices on the bus.

Checking the SCSI Termination

By default, the Internal LTO-1 and LTO-2 drives do not provide SCSI termination. If you use this default setting, you must place a SCSI bus terminator or a SCSI device with termination enabled at the end of the SCSI chain. Two examples of SCSI termination are shown in

The Internal LTO-1 and LTO-2 drives will provide terminator power if a jumper is placed on the termination power jumper pins (see “Terminator Power” on page 18).

Connecting a Power Cable

Attach a four-pin power cable to the power connector on the back of the drive. Figure 6 on page 20 shows the location of the power connector.

The recommended 4-pin power connector for internal drives is an AMP 1-48024-0 housing with AMP 60617-1 pins or equivalent.

Installing the LTO Driver

If you intend to use your drive with the Microsoft native backup applet on Windows Server 2003, Windows XP, or Microsoft Windows 2000 operating system, install the appropriate LTO driver. See the Tape Resource CD. This driver is not necessary with commercial backup application software.

Registering Your Tape Drive

After you install the internal tape drive, be sure to register it. Registering your drive ensures that you will receive the latest information about your drive, as well as other product, service, and support information. For your convenience, you can register your drive either through our Web site or by fax.

• If you have an Internet connection, please visit www.certance.com and select “Product

Registration” from the “Products” menu.

• If you do not have an Internet connection, complete the Registration Card included with your

package and either mail or fax it to the address or fax number on the Card.

Installing an Internal LTO-1 Fibre Channel Drive

This section describes how to install an internal LTO-1 drive equipped with a Fibre Channel LC Optical (FC) interface. Installing an internal LTO-1 FC drive involves the following steps:

1. “Configuring the Internal Fibre Channel Drive” on page 23

2. “Mounting the Internal FC Drive” on page 24

3. “Connecting a Fibre Channel Cable” on page 25

4. “Connecting a Serial Cable for Tape Libraries” on page 26

5. “Connecting a Power Cable” on page 27

6. “Registering Your Tape Drive” on page 27

Configuring the Internal Fibre Channel Drive

Before you install the tape drive in your computer, you may need to configure the drive’s hardassigned loop identifier. Jumpers located on the back of the drive (see used to configure the ID.

Figure 8 on page 23) are

Figure 8. Connectors and Jumpers on the Back of the LTO-1 FC Drive

Loop ID

Jumper Pins: 13–14, 11–12, 9–10, 7–8, 5–6, 3–4, 1–2

Default Setting: Loop ID 0000000

By default, the LTO-1 internal FC drive uses Loop ID 0000000 (no jumpers in place). You can change this Loop ID by placing jumpers on jumper pins 13–14, 11–12, 9–10, 7–8, 5–6, 3–4, 1–2.

Mounting the Internal FC Drive

You can mount the internal FC drive either horizontally or vertically, with the drive’s left side facing up (see

Figure 9 on page 24).

• If you mount the drive vertically, the left side of the drive must face up and the side of the drive

should be within 5 degrees of horizontal.

• If you mount the drive horizontally, the base of the drive must be within 15 degrees of horizon-

tal and the PCB side of the drive must face down.

Figure 9. Acceptable Mounting Orientations

Mount the drive in a 5.25-inch, full-height drive bay and secure it using two M3.0 X 5 metric screws on each side of the drive. Do not use screws longer than 5 mm or you may damage the drive. Figure 10 on page 25 shows the locations of the mounting-screw holes on the side and bottom of the drive, respectively.

Connecting a Fibre Channel Cable

The internal LTO-1 FC drive has two FC connectors that can connect to either a hub or a switch. In systems that support failover, both FC connectors can be used to allow hosts to maintain a connec tion with the drive if one connection fails. The internal LTO-1 FC drive is 100-M5-SN-I compliant and uses LC style connectors. Either 50 or 62.5µm multimode optical fiber cables can be used.

1. Turn off all power to the drive and the computer.

2. Attach the interface cable to either of the two LC optical interface connectors on the back of

the drive (labeled A and B in

3. In systems that support “failover,” connect the other port through separate loops or fabrics to

the same set of host computers. This way, if one connection fails, the other can be used to con tinue the data transfer.

Figure 11 on page 26).

Connecting a Serial Cable for Tape Libraries

The Internal LTO-1 FC drive includes an RS-422 serial interface for tape libraries. This connector is located on the lower left side of the back of the drive (see

Figure 12 on page 26).

Table 5 on page 26 shows the pin descriptions for the serial interface connector. The pins on this connector are set on 2-millimeter centers. The drive uses pin 1 to detect the presence of a tape library. The serial interface cable must connect this pin to the adjacent pin 3.
