Equipment Description

The Tape Array (T5) Rackmount Enclosure can house from one to five Quantum® DLT7000 or DLT8000
SCSI tape drives in a well-integrated package for use in rackmount applications. Included on the rear panel
of the T5, 10 HD68 SCSI connectors allow separate SCSI bus connections to each drive. Five drive SCSI ID
selection switches are also included on the rear panel.

The DLT tape drives are mounted in easily removed carriers, which slide into the front of the T5 chassis and
are retained with captive screws. The carriers contain SCSI and power connectors which dock with mating
connectors mounted inside the T5 chassis and provide all power and data connections between the drives and
the T5. The T5 Enclosure features a snap on/off front bezel, which can be easily snapped off for drive carrier
removal, and allows access to the media cartridges when in place.

Dual, redundant hot-swappable 300-watt power supplies provide all necessary operating voltages for the
DLT drives. Two cooling fans mounted on the T5 rear panel, and a self-contained cooling fan in each of the
power supplies provide drive cooling.

Power Supplies

Two redundant hot-swappable 300-watt power supplies provide operating voltages for the DLT tape drives
installed in the T5 Enclosure. The two supplies operate in parallel using proprietary power control and
sharing modules. Each supply plugs into the rear of the T5 and can be removed or replaced while the other
supply keeps the system fully operational. There is a normally green indicator on the T5 rear panel, at the top
of each power supply module, which extinguishes whenever the associated power supply fails, is turned off,
or is removed from the chassis.

Unpacking and Inspecting

Unpack the T5 chassis and visually inspect for any damage that might have occurred during shipment. Retain
the shipping carton in case reshipment is necessary.

Remove the top cover of the chassis and inspect the power supplies and cabling for component damage. If
any damage has occurred, notify ADIC immediately.

Each shipping carton should contain the following:

• A T5 Enclosure chassis with two removable power supply assemblies and internal SCSI data cables, as

ordered.

• Accessories box containing this Installation and Operating Guide, a right and a left side rack mount

support bracket, and an accessory bag containing an AC power cord and hardware necessary to rack
mount the enclosure.

Installing Tape Drives

1. Insert each drive carrier assembly into the unit. Check the carrier to insure proper docking connections.

2. Fully tighten the captive screw at the top and bottom of the carrier to secure it in the T5 chassis.

Caution

When inserting a carrier, be sure that the orientation of the carrier is
correct. The SCSI data cable connector should be nearest the top of the
chassis.

8 Installation

Installing SCSI Cables, Jumpers, and Terminators

Follow the steps on the following pages to connect your T5 to one or more SCSI busses. This involves
installing SCSI cables, jumpers (daisy chain cables), and terminator(s) onto the SCSI I/O connectors on the
rear panel of the T5.

Note

The interface cable(s) must be shielded – ADIC can supply you with the correct
type(s).

The T5 Enclosure can contain up to five SCSI DLT tape drives. Listed below are the SCSI configurations
supported by the T5 Enclosure:

• Each DLT drive can be connected to a separate SCSI bus, or from two to five drives can be daisy-

chained together and connected to the same SCSI bus.

• Each SCSI bus can be either single-ended or differential. They must each match the SCSI host they are

connected to.

• Termination can be active or passive. ADIC recommends using active termination on a single-ended

bus.

• All termination must be external. Never use internal terminators to terminate the drives.

SCSI Cables and Jumpers

1. Attach one end of the SCSI interface cable(s) to the connector(s) shown on the rear of your T5

Enclosure. Press firmly and secure the jackscrews.

2. Attach the other end of the SCSI interface cable(s) to the external connector(s) on the SCSI interface

card(s). Press firmly and secure the jackscrews.

Note

The jackscrews at both ends of the SCSI cable must be securely fastened in
order for the drives to communicate properly with the host computer.

3. If daisy-chaining two or more drives together for connection to a single SCSI bus, attach one end of the

SCSI jumper cable to one of the drives.

4. Attach the other end of the SCSI jumper cable to the external connector on an adjacent drive.

Installation 9

SCSI Terminators

External SCSI bus terminators should be used with either single-ended or differential drive configurations.

1. Install any required external terminator(s) on the appropriate SCSI connector(s) on the rear panel of

your T5 Enclosure.

Note

A drive should only be terminated if it is the last physical device on a SCSI bus.

SCSI ID Selection Switches

The SCSI ID selection switches are located at the top, near the center of the T5 rear panel. Each switch has
sixteen positions (0 through 15) and the selected ID is shown in the switch window.

1. To select a higher SCSI ID, push the “+” button. To select a lower SCSI ID, push the “-” button.

Notes

• Each device attached to an individual SCSI channel must be assigned a

unique SCSI ID.

• SCSI IDs are preset at the factory to the following: Drive 1 = 1, Drive 2 = 2,

Drive 3 = 3, Drive 4 = 4, Drive 5 = 5.

10 Installation

Installing in the Rack

Perform the following procedure to install your T5 Enclosure in a standard 19" rack:

15

Powering on the System

1. Plug the power cord into the back of your T5 Enclosure.

2. Plug the power cord from the T5 Enclosure into a grounded electrical outlet.

Use caution when plugging the power cord into an electrical outlet.
Hazardous voltages are present in the sockets of the outlet.

3. Plug the power cord from your host computer into a grounded electrical outlet.
Turn on the power switch located on the rear panel of the T5 Enclosure. Turn on the host computer power.

When the drives have completed their boot and initialization processes they are On-line on the appropriate
SCSI bus(ses).

Normal Operations

General Guidelines

Once your T5 Enclosure and your choice of application software are installed and configured, you can
automatically perform backup and restore operations via the application software. You do not need to
intervene unless the application software instructs you to exchange data cartridges.

Always follow these general-operating guidelines:

p Use only the recommended types of media cartridges described in this manual.
p Clean each of the DLT drives once a month, or whenever the Use Cleaning Tape LED is illuminated

on a drive front panel.

Drive(s) Power-on Self-Test

When you power up your T5 Enclosure, the DLT drives each perform a Power-on Self-Test (POST) while
the library is performing the Power-Up Checks. The sequence of events for each drive is:

1. The LEDs on the right front panel of the drive will turn on sequentially from top to bottom. All LEDs

will remain ON for a few seconds.

16 Operation and Maintenance

2. The LEDs on the left front panel of the drive will turn ON at the same time for about three seconds and

then turn OFF.

3. The Operate Handle, Write Protected, and Use Cleaning Tape LEDs will turn OFF. The Tape

in Use LED will blink while the tape drive initializes.

4 If your external SCSI bus terminator(s) have a Term Power LED it should also be illuminated.

Drive Status

After completion of the drive POST and initialization, each drive will be in one of the four states listed in the
following table:

Drive State Indicator Displays and Actions

1. No cartridge is present

2. A cartridge is present

and the handle is closed.

3. A cartridge is present,

but the handle is open.

4. The drive detects an

error condition.

The drive POST completes in about 13 seconds on each drive, and the drives will respond normally to all
commands. However, it may take longer for the media to become ready.

A. The Tape in Use LED turns OFF.
B. The Operate Handle LED turns ON.
C. The handle is unlatched.
D. The drive beeps momentarily.

The drive loads the cartridge. When the Tape in Use LED stops
blinking and stays ON, the tape’s actual density lights. For example, if
the actual tape density is 2.6, then the LED turns ON next to the 2.6
label. When the Density Override LED blinks, you can select a
density. The drive is ready for use.

The Tape in Use LED turns OFF. The Operate Handle LED
flashes. When the Tape in Use LED stops blinking and stays ON, the
tape’s actual density lights. For example, if the actual tape density is

2.6, then the LED turns ON next to the 2.6 label. When the Density
Override LED blinks, you can select a density. The drive is ready for
use.

Then all right or left side LEDs blink repeatedly. You may try to
unload the tape and reinitialize the drive by pressing the Unload key
or turn power OFF and then ON again. The right or left side LEDs stop
blinking and the drive tries to reinitialize. The LEDs turn ON steadily
again and then turn OFF if the test succeeds.

Data Protection

Warning

The Write-Protect switch on the data cartridge can be moved while the
cartridge is loaded into the drive. The drive will turn on the Write Protected
LED immediately. However, if the drive is writing to the tape, write protect
does not take effect until the write operation completes.

Before loading the data cartridge, if you move the Write-Protect switch to the left, the tape is write­protected; the Write Protected LED (orange) is ON and data cannot be written to, or erased from, the tape.

Before loading the data cartridge, if you move the Write-Protect switch to the right, the tape is write­enabled and data can be written to, or erased from, the tape (if it is not software write-protected).

After loading the data cartridge and during operation, if you move the Write-Protect switch from the write­protected position (to the left) to the write-enabled position (to the right), the tape becomes write-enabled
after a variable amount of time (seconds).

After loading the data cartridge and during operation, if you move the Write-Protect switch from the write­enabled position (to the right) to the write-protected position (to the left), the tape becomes write-protected

Cleaning the Drive Head

Cleaning the head should always be performed as the first step if the Use Cleaning Tape LED is
illuminated on the drive.

Note

The cleaning cartridge is exhausted after it has performed 20 cleanings. The
cleaning tape includes a label with 20 small boxes printed on it. Always place a
check mark in a box each time the tape performs a cleaning. Replace the
cleaning cartridge when it has performed 20 cleanings (all boxes will be
checked).

No routine maintenance is required apart from periodically cleaning a drive head whenever the appropriate
Use Cleaning Tape LED is illuminated.

Caution

Using cloth swabs, cotton swabs, cleaning agents, or unapproved cleaning
cartridges will void your warranty.

To clean the head, use a cleaning cartridge. Insert the cleaning cartridge in the drive following the Loading
the Data Cartridge procedure described earlier in this chapter. The drive will automatically clean the head.
When the cleaning operation is complete, the drive will illuminate the Operate Handle LED alerting you to
remove the cleaning cartridge.

Caution

Do not remove the cleaning cartridge before the drive sounds the beeper.

Follow the Removing the Data Cartridge procedure described earlier in this chapter to remove the cleaning
cartridge from the drive.

Operation and Maintenance 25

Note

If you load the cleaning cartridge into the drive after it has exhausted its
cleaning cycles, it will not clean the head (the cycle is noticeably shorter) and
the Use Cleaning TapeUse Cleaning Tape LED will be illuminated. Be sure to replace the cleaning
cartridge when the cleaning cycle is noticeably shorter.

Cleaning the Enclosure

The outside of the enclosure can be cleaned with a damp towel. If you use a liquid all-purpose cleaner, apply
it to the towel. Do not spray the enclosure.

Power Supplies

Introduction

The T5 comes with two "hot-swappable" 300-watt power supplies. Each auto-sensing (90 to 230 VAC, 50 to
63 Hz) supply provides operating voltages of +5 V @ 30 A and +12 V @ 14 A. Either supply will power the
chassis in the event that the other ceases to function. This is particularly important for DLTTM drives since
data loss can occur as a result of a power failure. Under nominal operating conditions both power supplies
provide approximately half of the chassis power, which results in extending each power supply’s mean-time­between-failure (MTBF) rating.

The power supplies are located at the rear of the T5 chassis. If either supply needs replacement, the entire
power supply assembly should be unplugged and replaced.

Power Supply Operation

The T5 provides dual redundant power supplies, either of which can power the T5 chassis and its installed
DLT drives. The power supplies normally operate in parallel and are controlled by proprietary power control
and sharing circuits. In the event of a power supply failure, the surviving supply immediately assumes the full
chassis load.

The T5 power supplies are "hot-swappable" and can be individually removed or replaced while the system is
operating. If a power supply fault occurs, or if a supply is removed or turned off, the corresponding indicator
will extinguish.

Note

Do not operate the system with only a single power supply for any longer than
is absolutely necessary. Doing so will not jeopardize the T5 in any way but it
does leave all data stored on the currently loaded tapes subject to becoming
unavailable.

Power supply removal requires only the unfastening of three captive retaining screws. Pulling straight out on
the handle will then de-couple the docking connectors and allow the supply to be taken directly out of the
chassis.

26 Operation and Maintenance

Caution

Removal of the wrong power supply can threaten the security of stored
data. Use the indicators on the rear panel of the T5 to be certain that the
correct power supply is being removed.

Power Supply Removal

Follow this procedure below to remove a power supply module.

1. Unfasten the three captive screws that retain the supply module in the chassis. Refer to Figure 3-1 for
the location of these screws.

Power Supply

Captive Retaining

Figure 3-3 Power Supplies

2. Use the handle on the module to pull the supply assembly from the chassis. The module docking
connector will disengage from the chassis connector.

3. Replace the power supply module as soon as possible and make sure that the module connector mates
firmly with the chassis connector.

4. Reattach the three captive screws to secure the supply module.

Fan Removal

Follow this procedure to remove and replace a chassis-mounted fan. The power supply fans are an integral
part of the power supply modules and are not field-replaceable.

Operation and Maintenance 27

1. Remove the two screws at the top of the fan, as shown in Figure 3.2

Figure 3.4 Fan Removal

2. Gently pull the fan away from its mounting location. Reach inside the T5 chassis and disconnect the red

DC power connectors, then remove the fan from the chassis.

3. Replace the fan as soon as possible making sure that the power connector on the fan is firmly mated

with the DC power connector in the T5 chassis.

4. Reinstall the two screws to secure the fan to the T5 chassis.

Troubleshooting and Diagnostics

This Chapter. . .

p describes the effects of high humidity on the T5 Enclosure.
p explains what to do when you need technical support.

31

High Humidity

If the drive detects high humidity, a warning is displayed by the drive LEDs. Any commands which are
currently being executed are aborted, and any commands which access the tape are rejected with a CHECK
CONDITION. In addition, the tape is unthreaded to prevent tape and head damage. As soon as the drive
detects that the humidity is at an acceptable level, it will once again respond to commands which access the
tape.

To minimize the chance of condensation, please observe the following guidelines:

• If you expose cartridges to temperatures outside the operating limits (5-40°C/40-113°F), stabilize them

before you use them. To do this, leave the cartridges in the operating temperature for a minimum of two
hours.

• Avoid temperature problems by ensuring that the ventilator slots at the front of the drive and the grille

on the side of the chassis are not obstructed so that the drive has adequate ventilation.

• Position the drive where the temperature is relatively stable, for example, away from open windows, fan

heaters, and doors.

• Avoid leaving cartridges in severe temperature conditions, for example, in a car standing in bright

sunlight.

• Avoid transferring data (reading from and writing to cartridges) when the temperature is changing by

more than 10°C per hour.

RMA (Return Material Authorization)

When it has been determined that there is a hardware problem with an ADIC system, ADIC Customer
Assistance Center will provide you with an RMA number. The warranty card must be completed and returned
to ADIC before the warranty is valid. (Customers who have not completed warranty registration can fax the
warranty card to ADIC. Call the ADIC Sales Department at [phone] for details.)

Warranty exchange service is provided at no charge to customers with validated warranties. If the item is
NOT in warranty, the repairs will be billable. Therefore, we will need a PO number at the time the RMA
number is issued. However, with first-time customers, it may be necessary to ship the system back C.O.D. for
the first repair until credit information can be obtained by the accounting department.

p Be sure all procedures in the ADIC user's manual have been checked and tried.
p When calling for an RMA number have the exact ADIC model number, serial number, and a brief,

descriptive explanation of the problem found. Be sure you give complete address information (e.g., any
mail stops or special codes) at the time the RMA is issued.

p Please send the complete ADIC system, i.e., interface cables, and the unit, if possible. A defective

component as well as the unit may have caused problems itself.

p The RMA number should be kept as a reference for calling to check on the status of an open RMA. It

must also be written on the outside of the package for identification purposes.
