and remains illuminated; the left LED turns off, and right 

LED remains off.

POST 

Failure

If POST fails, the middle and right LEDs illuminate 

steadily and the left LED flashes.

If a data cartridge is in place when power is turned on, all 

stages remain the same except Stage 3. It may take a 

considerably longer time for Stage 3 to complete due to tape 

rewind and searching operations that occur during that stage.
