Part 4. Care and Maintenance

Taking Care of the Drive

Safety Considerations

■ Power

• Be sure to use only 100-240 V AC.

• Avoid plugging into the same outlet as high-current equipment like copiers

or shredders.

■ Power Cable Precautions

• Do not crush the cable or place heavy items on it. If the cable insulation appears worn or broken, do not use the cable.

• Always unplug the cable by holding the plug: never pull the cable itself, as it will break.

• If the drive is not being used for a long time, unplug the cable from the outlet.

Avoiding Damage

■ Avoid shock and vibration

Intense shock, such as from dropping the drive, will damage it.

■ Environmental considerations

Do not store or use the drive in locations subject to:

• high humidity • excessive dust

• high temperature • intense vibration

• direct sunlight • sudden changes in temperature

■ Proper ventilation

To avoid overheating, install the drive where it will have free air circulation around the case, and do not cover it during operation. The drive can malfunction if the internal temperature rises too high.

■ Avoid sudden changes in temperature

If the drive is moved from a cool place to a warm place, or if the room temperature suddenly rises, moisture may condense inside the case. After a sudden change in temperature, wait at least one hour before turning the drive on. If the drive is turned on with condensation inside, and a cartridge is installed, the drive or the tape can be damaged.

16 Part 4. Care and Maintenance

■ Abnormal occurrences

If the drive behaves abnormally, or if it begins to smell or smoke, immediately unplug it from the wall outlet and contact your supplier for assistance.

■ Cabinet cleaning

Wipe the cabinet with a soft dry cloth. For heavy dirt, wipe with a soft cloth moistened with a gentle liquid soap, then wipe again with a soft dry cloth. Do not use alcohol, paint thinner, bug sprays or other volatile solvents, as they can damage the finish.

Part 4. Care and Maintenance 17

Taking Care of Cartridges

Use Precautions

• Avoid heavy vibration and dropping.

• The shutter on the face of the cartridge is opened automatically when it is

inserted into the drive. Do not open the shutter by hand, as touching the tape may damage it.

• The cartridge was carefully aligned during assembly at the factory. Please do not try to open it or take it apart.

• The write-protect switch on the face of the cartridge prevents the tape from being written to or accidentally erased. If you do not need to write to the tape, move this switch to the write-protect position (in the direction of the arrow).

• In case of a sudden change in temperature, condensation may interfere with

• Avoid unnecessary insertion and removal of cartridges if you do not need to

• When finished using the drive, remove the cartridge.

Storage Precautions

• Keep cartridges in their cases when not in the drive.

• Avoid storing cartridges in dusty places, in direct sunlight, near heaters or

• Do not place cartridges on the dashboard or in a storage tray in a car.

• La fonction lecture après écriture et le code de correction d’erreur de niveau trois garantissent une grande fiabilité des données.

• La compression des données permet un enregistrement de 260 Gigaoctets

sur une cassette de 230 m de long. La capacité d’origine est de 100 Gigaoctets pour une cassette de 230 m de long.

• Les données enregistrées sont automatiquement vérifiées pour la compression.

• L’interface Ultra 160 SCSI LVD/SE est entièrement compatible pour l’accès à l’ordinateur central.

• L’opération de lecture/écriture est possible pour les formats AIT-1, AIT-2 et AIT-3.

Le lecteur AIT SDX-D500C possède les caractéristiques suivantes :

• Le format évolué AIT permet une grande capacité d’enregistrement sur les cassettes de données AIT-1/AIT-2.

• La fonction lecture après écriture et le code de correction d’erreur de niveau trois garantissent une grande fiabilité des données.

• La compression des données permet un enregistrement de 130 Gigaoctets sur une cassette de 230 m de long.

La capacité d’origine est de 50 Gigaoctets pour une cassette de 230 m de long.

• Les données enregistrées sont automatiquement vérifiées pour la compression.

• L’interface SCSI Ultra large LVD/SE est entièrement compatible pour l’accès à l’ordinateur central.

• L’opération de lecture/écriture est possible pour les formats AIT-1 et AIT-2.

Ceci suppose un taux de compression de 2.6 : 1. Le degré du taux de compression des données atteint pendant l’enregistrement varie en fonction de l’environnement système et du type de données.
