After taking the action listed in Table 8 , power ON the DLT80 drive to rerun
POST. If all right-side or left-side LEDs blink again, hardware failure is likely.
Basic Health Check (BHC) Test
The BHC uses the tape drive system's firmware to check the various
EEROM-based information packets for log entries of events that occurred in the
previous 120 hours of operation. Based on that information, the system can report
on its "health." This test is pass/fail only.
To run the BHC:
1. Press and hold the Density Select button for five seconds. The Density
Override LED flashes for five seconds. After the five seconds, the top two
density LEDs will illuminate.
Note: If the Density Select button is held for less than five seconds, the BHC test will not
run and the density LEDs return to their original state.
2. Release, then momentarily hold the Density Select button. The top two
density LEDs will flash, indicating that the BHC test is running. The two
density LEDs continue to flash while the test proceeds.
