If a cleaning cartridge is inserted while the tape unit is in diagnostic
mode, drive cleaning will occur and the tape unit will then return to
normal operating mode. Return to step 1 to reenter diagnostic mode.
5.
At any time, self-testing can be stopped by pressing the eject button. After
the current operation is completed, the cartridge will be ejected and tape unit
will return to normal operating mode.
6. The Ready (left) LED will continue to flash while the following 4 steps are
performed:
v
The cartridge load sequence has a approximate duration of 30 seconds. The
center LED indicates tape movement.
v
The
hardware test
has an approximate duration of 2
½
minutes. During that
time, a static test is performed on tape unit electrical components. No tape
motion occurs during this step.
v
The cartridge load/unload test has an approximate duration of 1
½
minutes.
During that time, the Ready LED will continue to flash while a dynamic test
is performed on tape unit mechanical components. Two cartridge load cycles
are included.
v
Duration of the write/read test will vary, depending on what type of
cartridge is loaded into the tape unit. When an SLR100 Test Tape is used,
typical duration will be 5 minutes. Use of other cartridge types can increase
the write/read test duration to 30-40 minutes. During this test, the Ready
LED will continue to flash. The center LED indicates tape movement.
Interpreting the Results:
7. Test Passed:Cartridge is unloaded from the tape unit and all LEDs are off
,
when self-testing has completed successfully and no problems were detected.
Proper function of both the tape unit and tape cartridge have now been
verified.
Note: A solid amber light indicates that self-testing has completed successfully,
but the tape unit requires cleaning. Clean the tape unit by inserting an
IBM Dry Process Cleaning Cartridge (P/N 35L0844).
8. Test Failed:
The cartridge will remain loaded inside the tape unit and the amber LED
will flash,
when a problem is detected with either the tape unit or cartridge.
Note: To isolate failure to either tape unit or cartridge, return to step 1 and
repeat this self-test using a different scratch cartridge.
Incorrect cartridge:
9.
When the center (green) and right (amber) LEDs flash and a cartridge is
unloaded, the tape unit has determined that an incorrect tape cartridge has
been inserted, and self-testing cannot be performed. Verify that your tape
cartridge is
not one of the following:
v
Write-protected
v
Damaged
v
Unsupported media type
v
Media which is not write-compatible with tape unit.
Press the eject button, to end self-test and return the tape unit to normal
operating mode. Then return to step 1 and run the self-test using another
cartridge, or one which is not write-protected.
This ends the procedure.
