The controller has three lights that indicate the operational state of the tape library (see Figure 3). The lights are:
A green light that, when lit, indicates 24 V is available to power the robotic shuttle.
If the light is not lit, 24 V is not available because the shuttle could not move and
caused a power overload that dropped the 24 V, or because of problem with the power supply.
When the tape library controller determines that it has a problem with the robotics,
it removes the 24 V.
Also, when the front door is open, the 24 V is removed.
A green light that, when lit, indicates 5 V is present for the controller logic and tape drives.
A red light that, when lit, indicates a problem with the controller.
