v No: Load the correct media and retry the alternate installation.
This ends the procedure.
4. Is the alternate installation device powered on?
v Yes: Make sure that the alternate installation device is properly connected to the I/O processor or
I/O adapter card.

v The Power light flashes, then remains off.
v The Power light does not go on.
v Another indication of a power problem occurs.
Does one of the above power failure conditions occur?
v No: The alternate device is powered on and runs its power-on self-test. Wait for the power-on
self-test to complete.
Does the power-on self-test complete successfully?
– No: Go to the service information for the specific alternate installation device to correct the
problem. Then retry the alternate installation.
This ends the procedure.
– Yes: Retry the alternate installation.
This ends the procedure.
v Yes: Perform the following:
a. Go to the service information for the specific alternate device to correct the power problem.
b. When you have corrected the power problem, retry the alternate installation.
This ends the procedure.

Tape unit self-test procedure: For use by authorized service providers.
The following procedure is designed to allow you to quickly perform a complete set of diagnostic tests on a
6384 or 6387 tape unit, without impacting iSeries 400 system operation. This test can also be used to
verify good performance of individual tape cartridges.
Enter diagnostic mode:
1. Verify that a cartridge is not loaded in the tape unit. To unload a cartridge, press the eject button on
the front of the tape unit. If the cartridge does not eject, refer to Tape cartridge - manual removal.
2. Press and hold the eject button for about 6 seconds until the amber LED starts flashing slowly, then
release the button. The amber (left) LED will flash, indicating that the tape unit is waiting for a cartridge
to be inserted.
