ARCvault ® Series

SAS Tape Drive

Add-On Instructions

Overview & Notes

This document describes how to add a SAS half-height tape drive to an ARCvault loader or library.

WARNING: To reduce the risk of electric shock or damage to equipment, always remove the power cord.

CAUTION: Adding a SAS tape drive:

• Results in a library reconfiguration

• Disables any existing partitions in an ARCvault 48

• Requires the firmware to be at 5.06 or higher.

NOTE: The existing SAS drive cover on an ARCvault 48

supports up to four (4) drives (see Figure 8 ).

Unpacking

Carefully unpack and verify that you have all the parts:

• SAS tape drive with four M4x6 screws

• Internal SATA to SFF-8482 cable assembly

• ARCvault 48 lower drive bay kit

(Consists of the Secondary SAS drive cover, serial

Y-cable, air baffle, drive guides, and screws)

• These add-on instructions

Electrostatic Discharge Information

A discharge of static electricity can damage micro-circuitry or static-sensitive devices. To help prevent Electrostatic

Discharge (ESD), observe standard ESD precautions.

Preparing a Library for Installation

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

Power Off Library > OK (at power down message).

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

3. Determine the type of drive installation being done:

• To add a second tape drive to a drive bay, use the

“Add a Second Drive to a Drive Bay” section.

• To install a tape drive in an empty ARCvault 48

lower drive bay, use the “Add a Drive to the Lower

Drive Bay” section.

4. Go to the appropriate section to continue.

Add a Second Drive to a Drive Bay

This section covers adding a second half-height drive to an

ARCvault loader or library.

Remove the Drive Assembly

1. At the rear, remove the SAS cable from the drive cover

( Figure 1 ).

Reinstall the Drive Assembly

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

drive assembly back into the proper bay leaving about 1 inch (2.5cm) sticking out.

2. Attach the serial Y-cable to the drives ( Figure 5 ).

• Attach the black cable to the top drive.

• Attach the white cable to the bottom drive.

CAUTION: You MUST connect the BLACK cable to the TOP drive and the WHITE to the BOTTOM drive.

Add a Drive to the Lower Drive Bay

This section covers adding a drive in an empty lower drive bay of an ARCvault 48 using the following:

• Secondary SAS lower drive cover assembly (fan only)

• Left and right drive guides with four screws

• Serial Y-cable

• Air baffle with two screws

Remove the Drive Bay Baffle

Using a Phillips screwdriver, remove the two screws holding the drive bay baffle ( Figure 1 on page 1 ) and set the baffle and screws aside.

Prepare New Half-Height Drive

CAUTION: A single half-height drive must ALWAYS be installed in the top position in the drive bay.

1. Using the new M3x6mm screws, loosely attach the drive in the top position between the supplied guides with the thicker guide on the left (when viewed from the front) and the handles extending beyond the rear.

2. Slide the air baffle into the guides below the new drive, aligning it to the guide screw holes.

3. Using the new M3x6mm screws from the upgrade kit, loosely attach the air baffle to the guides ( Figure 6 ).

4. Tighten all six guide screws.

2. Attach the black serial Y-cable to the drive and to the unit serial cable ( Figure 7 ).
