LEDs
The front panel has two colored LEDs: the Tape Light and the Clean/Attention Light. The Tape Light flashes green to show activity (loading, unloading, reading, and writing). Steady green means a cartridge is loaded.
The Clean/Attention Light flashes amber to indicate head cleaning is needed or a cartridge is near the end of its life. Steady amber means a hard fault.

Data Cassettes
Media Life
HP DDS data cassettes are currently specified to 2000 passes over any part of the tape under optimal environmental conditions (50% relative humidity, 22 degrees C). During a tape operation, any one area of the tape may have multiple passes over the heads. This translates into approximately 200 to 300 backups or restores.
Under certain conditions, the life of your data cassette is less than 200 to 300 backups or restores. Replace your data cassettes after 100 backups or restores if your operating conditions meet any of the following criteria:
