Understanding the LEDs
LEDs during self-test
Using the LEDs for troubleshooting
Use the following table to interpret the front panel LED sequences and the appropriate action
to take, if any.
LED
Sequence
Your Ultrium Generation 2 tape drive has four LEDs (light emitting
diodes) on the front panel, which indicate drive status. These LEDs
provide useful troubleshooting information.
The tape drive performs a power on self-test whenever power is applied
or the drive is reset. The test takes about 5 seconds.
The green Ready light flashes several times and then remains on if self-
test passes. All other LEDs remain off.
If the self-test fails, the Drive Error and Tape Error LEDs flash, while the
Ready and Clean LEDs are off. This continues until the drive is reset.
Cause
All LEDs OFF.
Drive may not have
power, may be faulty or
may have been power
cycled or reset during a
firmware upgrade.
Ready and Clean OFF.
Drive Error and Tape Error
.
FLASHING
The drive has failed to
execute power-on self
test (POST).
Ready is ON.
The drive is ready for
operation.
Action required
Make sure the server is switched on.
If this is not on, check the internal power cable con-
nection and replace the cable if necessary.
If the power supply is present and all LEDs remain off,
press emergency reset (see page 23) or power cycle
the server. If it still fails, call for service.
Power cycle or reset the server.
If the error condition reappears, call for service.
None. This is normal.
