Actual compression ratios achieved depend on the redundancy of data files being recorded. Performance may vary when the tape drive reads data previously written to the DLT VS80 and DLT1 formatted data cartridges. Performance depends on the quality of the data cartridge you are reading, not the DLT VS160 tape drive. 81-81275-01 REV A02 September 2004 3-1 LED Indicators DLT VS160 Product Specification 3. 1 LED Indicators The tape drive has four light emitting diodes (LEDs). This section describes the functions of the LEDs. NOTE: The front panel controls and indicators are in the same locations on both the internal and tabletop tape drives. The tabletop tape drive has a Power LED. 3. 1. 1 Power-On Self-Test (POST) Indicator Activity Each time you apply power to the tape drive, or reset the tape drive, it performs a power-on self-test (POST). During POST, the LEDs illuminate one at a time, from left to right. First, the Ready LED (Green) comes on, followed by the Fault LED (Orange) approximately one second later, then the Clean LED (Orange) approximately one second later, then four seconds later the Media LED (Orange) illuminates. Each LED signifies a different portion of the power-on process. If no data cartridge is loaded in the tape drive, the Ready LED then illuminates steadily and POST is complete. This process takes approximately eight seconds. If a data cartridge is in the tape drive during POST, the Ready LED flashes until the tape drive executes a mid-tape load, which can take several minutes. As POST completes, the tape drive makes a faint buzzing noise for several seconds. The noise associated with this activity is normal for this technology and does not indicate a problem with the tape drive. 3. 1. 2 Normal Operation -- Ready LED Indicator Activity During normal operation, the Ready LED displays one of the three following states. The Ready LED acts independently of the other LEDs. Table 3-2. State Off On Blinking Normal Operation -- Ready LED Indicator Activity Description Indicates that there is no power to the tape drive.
