Hardware Compatibility

IBM has qualified the DLT 35/70 GB Internal DLT TApe Drive only for the IBM Server 704 family of systems. The 35/70 GB drive is 5.25-Inch FH form factor but does include extra length.
Consequently, most non-IBM systems would only be able to attach the 35/70 GB drive in an external SCSI enclosure.

   Appr. height: 86.3mm (3.4 -Inch)
   Appr. width: 148.3mm (5.84-Inch)
   Appr. depth: 243.8mm (9.6 -Inch)


The CD also contains backup applications that are used with other products but are not applicable to the 35/70GB DLT Internal Tape Drive.

Supported tapedrive configurations can be found on the IBM Server Compatibility Webpage at:

External Tape Drive

 

1    Power switch
   2    Power cord connector
   3    SCSI interface connectors
   4    SCSI ID-selection push switch


Configuration jumperblocks


 


 

1    SCSI ID jumperblock
   2    SCSI termination power jumper block
   3    SCSI termination jumper
   4    SCSI parity jumperblock
   5    SCSI disable parity jumper

Most SCSI adapters provide termination power.
However, if your SCSI adapter does not provide termination power, you must place a jumper in the enable termination power position 3 on the jumperblock 2.
Check the documentation that come with the PC or SCSI adapter for more information.
If the system does not generate parity, you can disable parity checking by placing a jumper in the disable parity position 5 on the jumperblock 4.
The DLT-drive is shipped with default SCSI ID address 5, use the below table for setup the DLT-drive SCSI ID on SCSI ID jumperblock 1.

  1.  Locate the SCSI cable (usually a 68-pin ribbon cable with one end  connected to the SCSI adapter) and find the next available connector that  is farthest from the adapter. Use all empty bus connectors beginning with  the one farthest away from the adapter to ensure better signal quality.

    NOTE: The SCSI adapter can be part of the computer system board  or can be an adapter installed in an expansion slot.

  2.  Attach the SCSI cable to the tape drive SCSI connector (rear side).  The fast/wide SCSI connector will only attach to the drive one way.
     Do not force the cable onto the drive.


Using the Drive - Button / Indicators

(See drawing on left side)

LED
Button
Function Description
1 Write Protect
(orange)
When indicator is on, the tape is write protected.
2 Tape in Use
(yellow)
When indicator is blinking, the tape is in motion.
When indicator lights steadily, the tape is loaded
and ready for use.
3 Use Cleaning Tape
(yellow)
When indicator is on, the drive head needs cleaning,
-or- the tape (media) is damaged,
-or- the tape head is damaged.
4 Operate Handle
(green)
When indicator is on, the Cartridge Insert/Release
handle can be lifted.
When indicator blinking, push the handle down and wait
for the indicator to turn solid green.
5 Unload Press this button to unload a tape or to reset the
tape drive.
6 Cartridge
Insert/Release
Lift this handle to insert or to remove a cartridge
when the Operate Handle indicator lights.
7 Select When the Density Override indicator 8 is flashing,
you can press this button to cycle through tape
capacity options.
8 Density Override
(yellow)
When indicator is lit, it indicates you use the
Select button 7 to change tape capacity.
9 Compress
(yellow)
When indicator is lit, data compression is enabled.
(Available in 10/15/20 and 35 GB density only)
10 35.0
(yellow)
When indicator lights steadily, the tape is recorded
at 35.0 GB capacity.
When indicator is blinking, it indicates you requested
this capacity.
11 20.0
(yellow)
When indicator lights steadily, the tape is recorded
at 20.0 GB capacity.
When indicator is blinking, it indicates you requested
this capacity.
12 10.0/15.0
(yellow)
When indicator lights steadily, the tape is recorded
at 10.0 or 15.0 GB capacity.
When indicator is blinking, it indicates you requested
this capacity.
13 6.0
(yellow)
When indicator lights steadily, the tape is recorded
at 6.0 GB capacity.
When indicator is blinking, it indicates you requested
this capacity.
14 2.6
(yellow)
When indicator lights steadily, the tape is recorded
at 2.6 GB capacity.
When indicator is blinking, it indicates you requested
this capacity.


Selecting Data Cartridges

 

The front of the cartridge has an orange Write Protect indicator 1, and Write Protect switch 2 to prevent accidential erasure. Slide the switch to the right to write enable 3 or to the left to write protect 4.
You can change the Write Protect switch before or after inserting the tape.
If you change the Write Protect switch while the tape is inserted, there is a delay of a few seconds before the Write Protect indicator changes.

NOTE: The backup/restore software might also provide write protection for the cartridge.


For writing data, use only DLT data cartridges
Any of the following data cartridges are acceptable and require no formatting or other media conditioning before use.


Selecting Record Capacity

You might want to decrease tape capacity for compatibility with older tapedrives, or increase capacity for better performance.

Insert a tape cartridge, and wait for the tape motion to stop and the Tape in Use indicator to light steadily. The capacity indicators show the current tape capacity.
If they are not lit, it means the tape is blank.

Density changes can occur only when writing from the beginning of the tape. You cannot mix capacities on a single data cartridge.


Press Select button to change density.
When the Density Override indicator is blinking, you can press the Select button to change the recording capacity of the tape.
Press the Select button until the desired capacity indicator is flashing.
The indicator will continue flashing until the tape drive begins recording in the new capacity. Then, the new capacity indicator is on steadily (the old capacity indicator is off).
