Diskette drive problems

v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See the parts listing in the Problem Determination and Service Guide to determine which components are
customer replaceable units (CRU) and which components are field replaceable units (FRU).
v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a
trained service technician.
Symptom
The optional diskette drive
activity LED stays lit, or the
server bypasses the diskette
drive.

General problems

v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See the parts listing in the Problem Determination and Service Guide to determine which components are
customer replaceable units (CRU) and which components are field replaceable units (FRU).
v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a
trained service technician.
Symptom
A cover lock is broken, an LED
is not working, or a similar
problem has occurred.

Hard disk drive problems

v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See the parts listing in the Problem Determination and Service Guide to determine which components are
customer replaceable units (CRU) and which components are field replaceable units (FRU).
v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a
trained service technician.
Symptom
Not all drives are recognized by
the hard disk drive diagnostic
test (the Fixed Disk Test).
The server stops responding
during the hard disk drive
diagnostic test.
Action
v If there is a diskette in the drive, make sure that:
– The diskette drive cables are correctly and securely connected.
– The diskette drive is enabled in the Configuration/Setup Utility program.
– The diskette is good and not damaged. (Try another diskette if you have
one.)
– The diskette is inserted correctly in the drive.
– The diskette contains the necessary files to start the server.
– Your software program is working properly.
v To prevent diskette drive read/write errors, make sure that the distance between
monitors and diskette drives is at least 76 mm (3 in.).
If the problem remains, replace the internal diskette drive (see the Problem
Determination and Service Guide on the IBM System x3400 Documentation CD).
Action
If the part is a CRU, replace it. If the part is a FRU, the part must be replaced by a
trained service technician.
Action
Remove the drive that is indicated by the diagnostic tests; then, run the hard disk
drive diagnostic test again. If the remaining drives are recognized, replace the drive
that you removed with a new one.
Remove the hard disk drive that was being tested when the server stopped
responding, and run the diagnostic test again. If the hard disk drive diagnostic test
runs successfully, replace the drive that you removed with a new one.
