SelectingDensity
You can select the density that the tape cartridge will record data by using the
front-panel Select button or by using a software command. In either case, the
new density does not take effect until a write from beginning of tape (BOT) is
executed. Until then, the original density will be used.
Note – Blank tape cartridges do not have default densities. The DLT7000 will
not light any LEDs on the left-side of the front panel until data has been
written to the tape.

Table 2-4 shows the densities that can be selected for the DLT7000 tape drive.
SelectingDensityUsingtheFrontPanel
To select density using the front panel:
1. Load the tape cartridge into the tape drive.
The Tape in Use LED blinks while the tape loads. After the tape is loaded,
the Tape in Use LED remains lit. The LEDs on the left side of the drive light
to show the tape cartridge’s prerecorded density.
2. Press the Select button until the LED(s) showing the desired density light.
The original density LED(s) will go out. The selected density LED(s) will be
on steady and the Density Override LED will blink. Then the selected
density will blink and the LED(s) for the original density and the Density
Override LED will be steady.
3. When a write from BOT occurs, the selected density will be used.
The selected density and the Density Override LEDs are on steady.
