Drive Warning Signals
The 4mm drives used in the VLS employ front panel LEDs to indicate SCSI interface
activity, drive fault conditions, and cartridge status. Figure 16 is a close-up of the
Sony SDT-5000 (SDT-7000/SDT-9000 are the same) drive and the location of the
warning LEDs. The LEDs on all other drives are located in approximately the same
place. Refer to the following tables for descriptions of the methods employed by
different drives to indicate activity, status, and fault conditions.
