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).

cartridge is near the end of its life. Steady amber means a hard fault.

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:
