NOTE:
The unassigned digits (B, D, and G) are not displayed when the options are incremented.
The unload push button must not be pressed more frequently than once per second while scrolling
through the maintenance choices. If the button is pressed more frequently, the currently selected
maintenance option will be executed instead of the desired scrolling operation.
Execute a maintenance function
The drive executes the maintenance function indicated by the character on the single-character display
when you press and hold the unload push button for two seconds. The single digit flashes the selected
maintenance function code during the execution of the operation. If the drive executes the function
successfully, the single-character display indicates 0. If the function fails, the status LED indicates
continuous yellow and the single-character display indicates the reason for the error by displaying an
error code from priority (lowest number) displays.
Exit maintenance mode
The drive exits maintenance mode when the unload push button is pressed twice within one second while
the single-character display indicates 0 or when the selected maintenance function is completed either
successfully or unsuccessfully or when the unload button is pressed during any currently executing
maintenance function.
Execute a dump operation when not in maintenance mode
The drive performs a dump operation when the unload push button is pressed and held for 10 or more
seconds. The microcode goes to its initialized state after a dump operation.
NOTE:
Data from a dump is for use by trained personnel for problem determination or engineering debug.
