Performing Front End (FE) Diagnostics
When performing Front End Diagnostics tests, it is strongly recommended to start with Auto Sequence,
especially if the system shows signs of an intermittent problem. As described in this section, the testing
sequence can be paused and restarted at any stage, providing a quick and easy method of reviewing
any detected faults.
NOTE:
When using Auto Sequence, most of the FE tests that can be performed manually (refer to the list numbered
1 through 8, below) are automatically performed, in sequence. However the following tests are NOT included
in Auto Sequence. These should be performed manually, as described in the appropriate sections:
•
•
NOTE:
During Auto Sequence, the system will automatically re-boot at least twice. This is normal and should
not give cause for concern.
The Front End diagnostic tests listed below can be initiated manually and performed by the system, as
described in this section. It is recommended that these diagnostic tests be performed in the following
sequence:
1.) Image Port (IMP) Diagnostic Test, as described in
page
2.) VME Bus (VME) Diagnostic Test, as described in
Configuration)" on page
3.) RFT Diagnostic Test, as described in
7-17.
4.) Front End Controller (FEC) Diagnostic Test, as described in
Diagnostic Tests (RFT Configuration" on page
5.) Beamformer (BF) Diagnostic Test, as described in

system.
6.) Front Board Assembly (FB) Diagnostic Test, as described in

7.) MUX Diagnostic Test, as described in
8.) H/W Report Diagnostic Test, as described in
NOTE:
If the system must be re-booted, do so. Continue testing from the point at which you were required to
reboot. If a failure occurs, re-boot the system and test again to verify the outcome of the test.
