LED Warning Conditions - DDS-DC Drive The following sections describe actions to take if the LEDs indicate a warning condition. High Humidity If the LEDs display the high humidity signal, the humidity is too high and 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 contact 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. If the LED indicators on your DDS-format drive display the Media Wear (Caution) condition, follow this procedure: 1. Check the system console for any tape error messages. A hard error during a read or write operation may have occurred. 2. Clean the heads with a cleaning cassette (HP92283K) as de- scribed in the "Cleaning the Tape Heads" section, later in this chapter. 3. Repeat the operation you performed when the Media Wear (Cau- tion) signal displayed. If the Media Wear (Caution) signal still displays, then the data cassette should be replaced. 4-5
