All OExx reference codes are tape unit microcode errors and should be
reported to your next level of support
Action
The tape unit is not communicating with the system.
If the tape unit cannot power on, go to "No Response Service Check
on page 1-35.
If the tape unit can power on and the power-on diagnostics run cor-
rectly, run test 2
to
isolate FRUs inside the tape unit If test 2 fails,
exchange the FRUs inside the tape unit in sequence as needed, and
run test 2 after each FRU is exchanged to verify the repair.
If test 2 was correct, attempt the customer's job again to get more
information. When a failure occurs, exchange the FRUs in sequence
as needed, and attempt the customer's job after each FRU is
exchanged to verify the repair.
The tape unit has stopped with *** XX in its status display where xx is
any number from 1 to 10. Exchange the FRUs as needed in the
sequence shown. Power on the tape unit after each FRU is exchanged
to verify the repair. If the power comes on successfully, the problem
has been corrected and this procedure is complete. If the power does
not come on successfully, continue this procedure with the next FRU
until the problem is corrected.
A reference code that is not listed was sent from the tape unit
to
the
system. Run test 0. If a listed reference code now occurs, go to that
reference code and follow the procedure for it If the reference code
that is not listed in the table continues to occur, exchange the FRUs as
needed in the sequence shown. Run test 0 after each FRU is
exchanged to verify the repair.
If the reference code continues to occur, contact your next level of
support.
The tape unit sent statistical data to the host system. This is not an
error condition. The FFFG reference code is logged when the tape is
unloaded by the host system.
If the tape is unloaded by pressing the Unload button, a FFFG reference
code will not be logged until a tape is loaded again and a command is
received from the host system.
The attached 9348 tape unit does not support synchronous data
transfer. Synchronous data transfer might improve the savefrestore
performance of the 9348 tape unit.
The tape unit will continue to operate and does not need immediate
attention. Call your service representative to install new EPROMs to
enable synchronous data transfer.
