Green
System in normal operation mode.
blinking
Orange <=> Green
FPGA_CONF_DONE = low
IF-FPGA not initialized -> probably FrontEnd (RFM board) or Power Supply
(RSP) issue
NO light
System is switched OFF (circuit breaker)
NO light
probably Power Supply (RSP) defect
7.3.2 Power Supply (RSP) - Status LEDs
On the backside of the ATX board near the fans 3 green status LEDs are mounted. These LEDs are used for
signaling the status of the Power Supply (RSP).
Figure 7-6 check green LEDs inside RSP
