This topic shows the status lights for the MLR3 and MLR1 tape units and provides information for interpreting the display.
The symbols located next to the status lights are the International Organization for Standardization (ISO) symbols that define the general function of the status lights as follows:
| Symbol | Definition |
|---|---|
| A | Disturbance. The amber status light flashes whenever the tape unit encounters an unrecoverable fault. It is on solid whenever the tape drive requires cleaning. |
| B | Ready. The green status light is on solid whenever the tape unit is ready to receive the tape backup commands. |
| C | Read-Write. The green status light flashes whenever the tape unit is moving the tape. |
The various on/off combinations of the status lights are shown in the following figure.
