Troubleshooting tables
Use the troubleshooting tables to find solutions to problems that have identifiable
symptoms.
If you cannot find a problem in these tables, see “IBM Dynamic System Analysis”
on page 59 for information about testing the server.
If you have just added new software or a new optional device and the server is not
working, complete the following steps before you use the troubleshooting tables:
1. Check the system-error LED on the operator information panel; if it is lit, check
the LEDs on the system board (see “System-board LEDs” on page 20).
2. Remove the software or device that you just added.
3. Run the diagnostic tests to determine whether the server is running correctly.
4. Reinstall the new software or new device.
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 Chapter 4, “Parts listing, Type 7377 server,” on page 125 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.
v Go to the IBM support Web site at http://www.ibm.com/systems/support/ to check for technical
information, hints, tips, and new device drivers or to submit a request for information.
Symptom Action
A cover thumbscrew is broken,
an LED is not working, or a
similar problem has occurred.
If the part is a CRU, replace it. If the part is a FRU, the part must be replaced by a
trained service technician.
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 Chapter 4, “Parts listing, Type 7377 server,” on page 125 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 Action
A hard disk drive has failed, and
the associated amber hard disk
drive status LED is lit.
Replace the failed hard disk drive (see “Removing a hot-swap hard disk drive” on
page 138 and “Installing a hot-swap hard disk drive” on page 138).
