After the cleaning cartridge has been inserted, the remainder of the cleaning
process is automatic. The DAT 160 tape drive:
1. Loads the cleaning cartridge into the tape drive
2. Cleans the drive by advancing the cleaning tape forward for approximately 30
seconds
3. Unloads the cleaning cartridge when the cleaning operation is complete
4. Indicates a successful cleaning operation by turning off the Cleaning status
LED (if the Cleaning LED was on prior to the cleaning process.)
Note: If the cleaning operation completes but the Cleaning LED remains on,
the cleaning cartridge may no longer be usable. Repeat the cleaning
procedure with a new cleaning cartridge. If the LED still remain on,
contact your authorized service representative. If the cleaning cartridge is
expired, discard it.
Note: Ensure the cleaning cartridge is supported by the drive. If a
non-supported cleaning cartridge is used, it will be ejected and the
Cleaning LED will remain ON.
To determine how many times a cleaning cartridge may be used, check the
information printed on the cartridge. If you attempt to use a depleted cleaning
cartridge, the DAT 160 tape drive automatically detects the error and ejects the
cartridge. If the Cleaning status LED was on prior to the cleaning process, it
stays on; if the Cleaning LED was off, the depleted cartridge causes the LED to
come on.
If a system error occurs, clean the drive and retry the operation. If the operation
fails, replace the data cartridge, clean the drive again, then retry the operation.
DAT 160 Tape Drive Self-Test Procedure
The DAT 160 tape drive can run a diagnostic self-test to find problems. To run the
self-test follow the following procedure:
Enter Diagnostic Mode
1. Verify that a tape cartridge is not loaded in the drive. To unload a cartridge,
press the eject button on the front of the drive.
2. Press and hold the eject button for 7 seconds, until the green Ready LED starts
flashing rapidly, then release the button. The Ready LED will continue flashing,
indicating that the drive is waiting for a cartridge to be inserted.
Running the Self-Test
3. Start the self-test by inserting a DAT160 test tape (P/N 23R5636). If a test tape
is not available you can substitute a partially written tape which has no useful
information on it.
Attention: Use a cartridge that does not contain customer data. During this
self-test, the cartridge data will have a test pattern written at the end of any
existing data, and any customer data may no longer be accessible.
Note: Overall test duration is about 3 minutes with a blank DAT160 test tape.
Duration with a partly written tape will be significantly longer due to
the time taken to space to the end of existing data. With a fully written
cartridge the self-test will still be able to write the small amount of data
it needs to write, but can take up to 10 minutes to complete the test.
