A Using the Tape Drive

A1 Handling the Tape Drive

and Data Cartridges

Handling the Tape Drive

!Do not carry the tape drive by inserting your fingers into

the receiver area. You could damage the tape drive if you

lift or carry it in this manner.

Do not stand the tape drive on its front panel.

Always place the tape drive on a flat, stable surface.

Avoid dusty, humid, or smoke-filled areas.

Use proper Electrostatic Discharge (ESD) protection.

Allow at least 6 inches of space behind the drive for

ventilation.

Handling Data Cartridges

Protect cartridges from shock, vibration, moisture, direct

sunlight, dust, smoke, and magnetic fields.

Use the slide-in labels provided. Do not use adhesive

labels or Post-it®notes, and do not write on the cartridge.

Never touch the tape or tape leader. Dust and oils from

your skin contaminate the tape and affect performance.

Keep cartridges in their protective cases when not in use.

Store data cartridges vertically.

!Always visually inspect a data cartridge before placing it

in the tape drive. If it is damaged, do not use the cartridge.

B4

!Never power off the tape drive while it contains a

cartridge.

cartridge from the tape drive. When

you press Eject, the tape drive

finishes writing data to the tape,

then ejects the cartridge.

A3 Loading and Unloading

Data Cartridges

To Load a Data Cartridge

1. Insert the data cartridge into the receiver on the front of the

tape drive.

2. Push the cartridge completely into the receiver.

The green Drive Status LED (A2)flashes as the tape loads.

When the tape reaches the Beginning of Tape (BOT) marker,

the Drive Status and Drive Density LEDs (A2)light

steadily, indicating that the cartridge is ready for use.

To Unload a Data Cartridge

1. Press the Eject button on the front bezel.

The tape drive completes writing data to the tape, and the

green LED (A2) flashes as the tape rewinds.

When the tape reaches the BOT marker, the tape drive ejects

the data cartridge. The green LED lights steadily.

2. Remove the cartridge from the tape drive and return it to its

plastic case (A1).

Cleaning the Tape Heads | A4

A4 Cleaning the Tape Heads

Over time, ambient pollution and particulates in the

environment contaminate the tape heads. The tape drive

indicates when cleaning is required by illuminating the

yellow Cleaning Required LED. A2

!Do not clean the tape heads unless the Cleaning Required

LED is illuminated.

!Use ONLY the SDLT CleaningTape. Other cleaning tapes,

such as CleaningTape III or DLT VS CleaningTape, are

incompatible with the SDLT 220/320 tape drive heads.

To Clean the Tape Heads

1. Insert a Super DLTtape cleaning cartridge (the brand name

to look for is SDLTtape™ CleaningTape) into the tape

drive.

The green Drive Status LED flashes and the cleaning cycle

begins automatically.

When the cleaning cycle completes, the tape drive

automatically ejects the CleaningTape; turns off the Cleaning

Required LED; and steadily illuminates the Drive Status

LED.

2. Remove the CleaningTape, place it back in its plastic case,

and mark the label after each cleaning.

Note: On the last cleaning, the tape drive does not eject the

CleaningTape. Use the Eject button on the front of the

tape drive to eject the expired cleaning cartridge and

dispose of it.

B1 | Super DLTtape Media

B Using Data Cartridges

B1 Super DLTtape Media

From the outside, the Super DLTtape I cartridge looks very

similar to the DLTtape IV cartridges. The basic geometry,

write-protect switch, and label space are unchanged from the

DLTtape IV cartridge. This simplifies the integration of

Super DLTtape into existing operating environments and

into automated tape libraries.

The Super DLTtape I cartridge is easy to recognize; it has

a different color (green) than the DLTtape IV cartridge

(charcoal gray) and contains a distinctive pattern molded

into the shell. The Super DLTtape I cartridge has a keying

feature to ensure that it cannot be loaded into previous

generation DLTtape drives.

Both the SDLT 220 and SDLT 320 tape drives feature an

optional backward-read compatibility (BRC) mode. When in

BRC mode, the drives are capable of reading DLTtape IV

tapes with DLT 4000, DLT 7000, DLT 8000, and DLT 1

formats. The Backward-Read Compatibility table below lists

BRC rates for the Super DLTtape drive.

Backward-Read Compatibility

Format Cartridge Type Native Capacity (GB)

Native Read Transfer

Rate (MB/second)

SDLT 320 SDLT I 160 16.0

SDLT 220 SDLT I 110 11.0

DLT 8000 DLT IV 40 4.0

DLT 7000 DLT IV 35 3.5

DLT 4000 DLT IV 20 1.5

DLT 1 (Benchmark) DLT IV 40 3.0

Notes:

• Transfer rates quoted are nominal, measured reading uncompressed data.

• Non-SDLT drives will eject a cartridge written in SDLT 320 format.

• The SDLT 320 can read and write the SDLT 220 format at the native SDLT 220 transfer rate of

11.0 MB/s.

Write-protecting Data Cartridges | B2

B2 Write-protecting Data

Cartridges

To prevent accidental erasure of your data, each data

cartridge has a write-protect switch. When active, this switch

prevents the tape drive from writing data to the cartridge.

!For valuable data, always make sure the cartridge is

write-protected before inserting it into the tape drive.

To enable write-protection:

Move the write-protect switch left so that the bright

orange rectangle is visible.

To disable write-protection:

Move the write-protect switch right so that the orange

rectangle is not visible.

On the SDLT 220 tape drive, when you insert a write-

protected cartridge into the drive, the amber LED on the

front panel lights.

On the SDLT 320 tape drive, the amber LED indicates the

format of the tape: Light on or blinking indicates SDLT 220

density; light off indicates SDLT 320 density.

Move switch down to

write-protect media.

Orange indicates

write-protected.
