Configuring and Operating the DLT2500 Mini-Library
DLT2000/DLT2500/DLT2700 Cartridge Tape Subsytem 4-15
4.7.1 Front Panel Density Select Mode
To select density via the front panel:
1. If a tape is loaded in the drive, the display shows the tape's pre-recorded density.
2. The user can use the mini-library OCP at various times, not just after you load a
tape. Density selection is inactive until you issue the write from BOT command.
The controller remembers the density selection state until you do one of the
following:
• Change the density selection
• Press the Open button to open the door
3. Enter Density Select mode by pressing the Display Mode button and then the
Select button on the OCP. Using Density Select mode always overrides a host
selection.
Example
If you loaded a tape with a prerecorded 2.6 density and you use Density Select mode to
select 10 density:
Before a write from BOT occurs, you should see the 2.6 show steady, and the 10 and
OVR flash in the display:
LDR RDY
2.6 10 OVR
After a write from BOT occurs, you should see the selected density 10 and the OVR
show steady in the display:
LDR RDY
10 OVR
