The Power-On Self-Test
When you power on the HP SureStore DLT drive, it performs a self-test to
check that it is functioning correctly. The test takes about 13 seconds if no
tape cartridge is loaded, and the pattern of front panel lights at the end
tells you the results of the test.
During the test the following occurs:
1 All the lights on the left side of the front panel are lit simultaneously
while the lights on the right side are lit in sequence.
2 The lights go off, leaving the “Tape in Use” light flashing.
3 The self-test finishes. If the test is successful and no cartridge is in the
drive, the only light showing will be the green “Operate Handle” light,
lit steadily.
After a Successful Self-Test
No cartridge in the drive:
• Only the green “Operate Handle” light is lit.
Cartridge in the drive—Cartridge Locking Handle down:
1 The “Tape in Use” light flashes while the drive loads the cartridge.
2 The “Tape in Use” light stops flashing and stays lit; the density and
“Compress” lights show the tape cartridge’s density.
When the “Density Override” light flashes, you can select a new density
if you need to. See page 5-5.
Cartridge in the drive—Cartridge Locking Handle Up:
Caution It is inadvisable to leave a drive in this state.
• The “Operate Handle” light flashes. All other lights are off.
Lower the Cartridge Locking Handle to load the cartridge.
After an Unsuccessful Self-Test
All left side or right side lights flash:
The test has failed. See Chapter 6, “Troubleshooting,” for what to do.
No lights are lit:
The drive is probably not receiving power. Check the power supply. See
Chapter 6 for more details.
