Recovery procedures for specific hardware errors

When a hardware failure occurs, a message displays on the control panel. If the failure occurs

during the power-on sequence, DEVICE FAILED displays. If the failure occurs when loading

a disk you may see LOAD ERROR or FULL. If a failure occurs while you are running a test,

TEST FAILED displays. When you press ENTER, the jukebox displays information about

the hardware failure from the error log.

The jukebox firmware can detect broken components such as a dead motor, but if failures are

due to marginal or random problems, the failing component may induce errors in other

components. For example, if the electronics produce an intermittent error or if friction

increases on a part, different components of the jukebox may appear to fail. Several error

codes may be displayed as a result of one problem.

Table 5 shows the hardware error codes possible and recovery procedures for specific

hardware errors.
