4.11 Self Test and Error Codes
After power on the 10 GB C&C Card performs a test sequence. If a
critical error occurs the board cannot start up. In this case three status LEDs
(the power on LED, the management port LINK LED and the ACT LED) are
blinking. In case of non critical errors the corresponding flag in the Hardware
Error register is set. The power on test sequence is the following:
1. Microcontroller SDRAM, EEPROM, External Flash1 and Flash2 test.
SDRAM and EEPROM errors are critical. (In case of Flash1 error the
WEB interface is not working, only the UDP based communication is
active.)
2. Loading the settings from the EEPROM. An error is critical.
3. Waiting for FPGA program loading (boot). The card waits 2 seconds as
a maximum. (In case of FPGA program error the management port of
the controller is active, the user can read the Hardware Error register.)
In case of critical error the three status LEDs blink N times depends on
the error type.
