When the Nucleus Controller powers up, if it detects a difference between what was
configured last and the current configuration, it applies the new configuration and
the D15 LED shows an FPGA validation error, see Figure 182 The next time the
Nucleus Controller is rebooted there is no mismatch and therefore the D15 LED is
off. If the D15 LED remains on, it could indicate a fault in the interface to the
modules.
An FPGA interface validation error occurs if the software detects a difference
between the modules configured in the database and the configuration last written
D15
to the modules in the frame. This can happen when a reconfigure is done to
recognise new cards and the Nucleus Controller is rebooted.
On a dual processor system, the D15 LED can indicate a mismatch between the
databases on the two controllers.
•
Red = FPGA interface validation error
•
Off = no error
