LED Warning Conditions
The following sections describe actions to take if the LEDs indicate a warn-
ing condition.
High Humidity If the LEDs display the high humidity signal, the humidity is
too high. The drive does not perform any operations until the humidity
drops.
Self-Test (Failure) If the LEDs display the self-test (failure) signal, a fault
was diagnosed during the self tests. Note the pattern of the pulses and con-
tact your local service representative.
Media Wear (Caution) Hewlett-Packard DDS drives continually monitor the
number of errors they have to correct when reading and writing to a tape to
determine tape wear and tape head cleanliness. If excessive tape wear or
dirty tape heads are suspected, the drive warns you by displaying the Media
Wear (Caution) signal on the LED indicators.
