Indicates that the status of this LED does not
depend on the specific tape drive condition. This
means that certain tape drive conditions may result
in a combination of two or more of the LED states
in the chart.
For example, if you need to clean the tape drive
while a DLT1 tape is loaded, both the
Clean LED
and
Media LED are on steadily. If an internal
write/read diagnostic fails due to a permanent
write error, both the
Fault LED and Clean LED
blink slowly.
