7. Examine the I/O module LEDs. If an I/O module has an amber LED:
a. Replace the I/O module as follows:
a. Detach the SAS cable connecting the I/O module to the X9700c controller.
b. Ensure that the disk drawer is fully pushed in and locked.
c. Remove the I/O module.
d. Replace with a new I/O module (it will not engage with the disk drawer unless the
drawer is fully pushed in)
e. Re-attach the SAS cable. Ensure it is attached to the "IN" port (the bottom port).
b. Re-seat controller 1 as described below in the section
(page 150).
c. Wait for the controller to boot, and then check the seven-segment display.
If the seven-segment display shows "on" then the fault has been corrected and the
system has returned to normal and you can proceed to step 1 1.
If the seven-segment display continues to show an Hn 67 or Cn 02 code, continue
to the next step.
8. One of the I/O modules may be failed even though the amber LED is not on. Replace the I/O
modules one by one as follows:
a. Remove the left (top or bottom as identified in step 4) I/O module and replace it with a
new module as follows:
a. Detach the SAS cable connecting the I/O module to the X9700c controller.
b. Ensure that the disk drawer is fully pushed in and locked.
c. Remove the I/O module.
d. Replace with a new I/O module (it will not engage with the disk drawer unless the
drawer is fully pushed in)
e. Re-attach the SAS cable. Ensure it is attached to the "IN" port (the bottom port).
b. Re-seat the appropriate X9700c controller as described below in the section
an X9700c controller" (page
c. Wait for the controller to boot.
If the seven-segment display shows "on," then the fault has been corrected and the
system has returned to normal and you can proceed to step 1 1.
If the seven-segment continues to shows an Hn 67 or Cn 02 code, continue to the
next step.
d. If the fault does not clear, remove the left I/O module and reinsert the original I/O module.
e. Re-seat the appropriate X9700c controller as described below in the section
an X9700c controller" (page
f. Wait for the controller to boot.
If the seven-segment display shows "on," then the fault has been corrected, the system
has returned to normal, and you can proceed to step 1 1.
If the seven-segment display continues to shows an Hn 67 or Cn 02 code, continue
to the next step.
g. If the fault does not clear, remove the right I/O module and replace with the new I/O
module.
h. Re-seat the appropriate X9700c controller as described below in the section
an X9700c controller" (page
9. If the seven-segment display now shows "on," run the exds_stdiag command and validate
that both controllers are seen by exds_stdiag.
10. If the fault has not cleared at this stage, there could be a double fault (that is, failure of two
I/O modules). Alternatively, one of the SAS cables could be faulty. Contact HP Support to
