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.

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.
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).
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.
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.
