Introduction

This Chapter. . .

p provides a physical description of the switches, indicators and connectors on the rear panel of the T5 Enclosure.

1

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.

Power Supplies

Figure 1-3: T5 Rear Panel

4 Introduction

Cooling

The T5 enclosure is cooled by four fans, two of which are contained in the power supply modules and whose status is reflected by the power supply status indicators. The other two fans are mounted on the chassis rear panel and are easily removed and replaced while the system remains in operation.

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 daisychained 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

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 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.

2. A cartridge is present and the handle is closed.

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.

3. A cartridge is present, but the handle is open.

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.

4. The drive detects an error condition.

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.

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.

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 after a variable amount of time (seconds).

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 DLT

TM

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.

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

Screws

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.

Troubleshooting and Diagnostics

This Chapter. . .

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 (425) 881-8004 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.
