Operating the AIT Drive Front Panel LED Indicators The following table describes and explains the front panel LEDs.
Operating the AIT Drive Importance of Using Compaq-Approved Cassettes Compaq-approved cassettes are thoroughly tested to meet high-quality standards. Before Compaq recommends a cassette, the quality and reliability of the magnetic media and the cassette are evaluated. Do not use unapproved cassettes; they may not be compatible with Compaq tape drives.
Operating the AIT Drive Forcing the Ejection of a Cassette CAUTION: You can lose data if you force the ejection of a cassette or the cassette can end up invalidly formatted because End of Data (EOD) may not have been written. Force an ejection only as a last resort; never use it as a quick way to eject the cassette. A cassette can be forced to eject when immediate ejection is required, even at the risk of losing data. To eject a cassette immediately, hold the eject button down for at least 5 seconds.
Operating the AIT Drive Write-Protecting a Cassette The cassette has a write-protect switch 1 to prevent accidental erasure of data. Before loading the cassette into the drive, position the write-protect switch on the front of the cassette. By moving the switch to SAFE, the cassette is write-protected and by moving the switch to REC, the cassette is write-enabled. 1 Figure 3–2: Cassette write-protect switch NOTE: Your tape switch may differ from the illustration.
Operating the AIT Drive Cassette Handling and Storage For longer life of recorded or unrecorded cassettes, store cassettes in a clean environment with these conditions: • Keep the cassette out of direct sunlight and away from heaters and other heat sources. • Store the cassette in temperatures between 5° C and 32° C (41°F to 89.6°F).

4 Cleaning the AIT Drive Reliable backup of your system is the product of at least four components: • A reliable tape drive • Quality cassettes • Regular backup schedule with backup media stored off-site • Routine tape drive maintenance Compaq tape drives are designed to operate reliably under worst-case conditions; however, they require simple routine maintenance to operate efficiently. Regular cleaning is the most essential step in properly maintaining a tape drive and preventing errors.
Cleaning the AIT Drive When a drive is cleaned according to a regular schedule, one cleaning cycle typically removes accumulated dirt and particle deposits. However, in a dusty environment, one cleaning cycle may not fully clean the AIT drive read/write heads. Up to four cleaning cycles may be necessary to fully clean the drive.
Cleaning the AIT Drive Tape Drive Cleaning Procedure CAUTION: Do not use alcohol or a cleaning solution to clean AIT drives. Do not clean read/write heads with a cotton swab. Fibers from a cotton swab can cause permanent damage to the head. 1. Insert the cleaning cassette into the drive. The drive automatically takes the cassette, loads it, and cleans the heads. When cassette cleaning is finished, the drive ejects it. 2.
