LED Indicators
The tape drive has four light emitting diodes (LEDs). This section describes the functions of the LEDs.

OTE
:
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. All LEDs turn
off momentarily. 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.
Normal Operation — Ready LED Indicator Activity
State
Description
Off
Indicates that there is no power to the tape drive.
On
Indicates that power is on, no data cartridge is loaded, or a loaded data cartridge is
idle with no tape motion.
Blinking
A data cartridge is in the process of loading, or there is tape motion on a loaded data
cartridge. Tape motion includes reading, writing, locating, rewinding, calibrating,
and so on.
