Blinking–medium (approximately twice per 

second)

Blinking–fast (approximately three times per 

second)

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 

 LED 

and 

 LED are on steadily. If an internal 

write/read diagnostic fails due to a permanent 

write error, both the 

 LED and 

 LED 

blink slowly.
