Overland Storage ARCvault LTO-4 Replacement Instruction

Brand: Overland Storage

Model: ARCvault LTO-4

Type: Replacement Instruction

This document describes how to do the following options:

• Replace existing drives in a drive bay with an LTO-4

SCSI or FC tape drive in an ARCvault loader or library.

• Add a new LTO-4 SCSI or FC tape drive in an empty

drive bay of an ARCvault 48 Library.

WARNING: To reduce the risk of electric shock or

damage to equipment, remove the power cord.

CAUTION: Adding a new tape drive results in a

reconfiguration of the library. In the ARCvault 48, it also

automatically disables any existing partitions.

IMPORTANT: When installing an LTO-4 drive into an

empty ARCvault 48 drive bay, an ARCvault Drive Bay

Upgrade Kit (available separately) is required. If two half-height

drives exist in a drive bay, both must be removed.

Unpacking

Carefully unpack and verify that you have all these parts:

• LTO-4 full height tape drive (SCSI or FC)

• Four M3x5 screws

• LVD SCSI cable, 2m (6.5 ft.) (SCSI add-on drive only)

• SCSI terminator (SCSI add-on drive only)

• These remove & replace instructions

Electrostatic Discharge Information

A discharge of static electricity can damage micro-circuitry

or static-sensitive devices. To help prevent Electrostatic

Discharge (ESD) damage, observe these and other

standard ESD precautions:

• Transport and store items in static-safe containers.

• Make sure you are always properly grounded.

• Avoid touching pins, leads, or circuitry.

Use this procedure to install a new LTO-4 full-height drive in a drive bay currently containing one or two drives. The new

drive replaces the existing drives. To install a drive in an empty drive bay, use the “New Drive Installation” on page 3.

Remove the Drive Assembly

1. To power down the unit from the Operator Control

Panel (OCP), press Power > Power Off Library >

OK (at the power down message).

2. After the unit has shut down, remove the power cord.

3. At the rear, remove either the SCSI cables and

terminator or FC cables from the appropriate drive

cover (Figure 1).

4. Loosen the two thumbscrews on the drive cover.

5. Remove the drive cover as follows:

a. Gently pull the drive cover out and hold it about

2 inches (5cm) below the drive bay (Figure 2).

b. Unplug the fan wiring from the fan connector.

c. For a SCSI drive assembly, using the guide handles,

pull the assembly out about 1 inch (2.5cm) and

unplug the SCSI cables from the drives.

d. Set the old drive cover aside.

6. Unplug the power and serial cables from the drive

assembly and position them off to the right.

7. Grasp the drive assembly guide grips and carefully

slide the assembly out of the unit.

Install the New Drive

1. Check the jumper pins on the new drive to confirm

they are at the default settings (ON-off-off-off-ON-ON).

2. Remove the drive assembly guides (Figure 3) located

on the sides of the assembly.

Figure 3. Remove Drive Assembly Guides (Single HH Drive)

3. Attach the drive guides to the sides of the new drive

(Figure 4) with four new M3x5mm screws.

Be sure the thicker guide is on the left side (when

looking at the front of the drive).

Reinstall the Drive Assembly

1. With the wiring positioned off to the right, slide the

drive assembly back into the drive bay.

For a SCSI drive assembly, leave the assembly sticking

out about 1 inch (2.5cm).

2. Attach black cable of the serial Y-cable to the drive

(Figure 5).

CAUTION: You MUST connect the BLACK serial

cable to the new LTO-4 drive for the unit to operate

correctly.

Use this procedure to install a new LTO-4 drive into an

empty drive bay on an ARCvault 48.

IMPORTANT: An ARCvault Drive Bay Upgrade Kit

(available separately) is required for this procedure. The

kit contains:

• 4-port drive cover assembly

• Left and right drive guides with four screws

• Serial Y-cable

• Air baffle with two screws (not used for this installation)

Remove the Drive Bay Baffle

1. From the Operator Control Panel (OCP), press Power

> Power Off Library > OK (at the power down

message) to power down the unit.

2. After the unit has shut down, remove the power cord.

3. Using a Phillips screwdriver, remove the two screws

holding the drive bay baffle (Figure 6).

4. Remove the baffle and set it aside.

Install the New Drive

1. Check the jumper pins on the new drive to confirm

they are at the default settings (ON-off-off-off-ON-ON).

2. Attach the drive guides to the sides of the new drive

(Figure 7) with four new M3x5mm screws.

Be sure the thicker guide is on the left side (when

looking at the front of the drive).

Install the New Drive Assembly

1. With the wiring positioned off to the right, slide the

drive assembly back into the drive bay.

For a SCSI drive assembly, leave the assembly sticking

out about 1 inch (2.5cm).

2. Attach the main plug of the new serial Y-cable to the

serial cable going into the unit.

3. Attach the black cable of the Y-cable to the drive

(Figure 8).

CAUTION: You MUST connect the BLACK serial

cable to the new LTO-4 drive for the unit to operate

correctly.

IMPORTANT: For optimum performance of the library, it is

recommended that each drive be connected to the host

by a separate bus.

1. Install the drive cover as follows:

a. Holding the drive cover below the drive bay opening,

plug in the fan connector.

b. On a SCSI system, reattach the SCSI drive cables,

and slide the drive assembly the rest of the way

into the drive bay.

c. Carefully seat the drive cover and tighten the two

thumbscrews.

CAUTION: Be sure that all drive wiring is secure in

the space between the drive assembly and the

drive cover.

2. Reconnect the SCSI cables and terminator or FC

cables to the rear of the unit.

3. Plug in the power cord and power on the unit.

4. During POST, as soon as the reconfiguration message

appears, press OK.

5. After the library reboots, check the OCP Status to

verify that the unit recognizes the new drive.
