Front Board Assembly (FB) Diagnostic Tests
The FB diagnostics tests check the FB circuits and boards. To avoid frequent rebooting of the system,
these tests must be performed in the sequence described below. When performing FB tests out of
sequence, follow the instructions displayed in the
Comment
area of the
FE Diagnostics
dialog box, and
reboot as required. Refer to
Chapter 5 - Components and Function (Theory)
for additional details about
the FB circuits and boards.
Note:
Before performing the FB tests, make sure that the RFI (or IMP, VME Bus, RFT, FEC) and
BF diagnostic tests have been performed, as described beginning on page

If the FB tests are performed without first performing these tests, and errors are identified, you must
perform the following tests (
in the order listed
) to ensure that the FB is in fact the source of the error:
