Troubleshooting
11.1.5 Check Voltage Conversion Status
The circuit board includes multiple LEDs to indicate whether the board is receiving and converting
voltages to support multiple components on the board.
LED1, LED2 and LED3 illuminated
► If the “LED1” LED is on, then the board is receiving 24 V power.
► If the “LED2” LED is on, then the board is converting 24 V power to 5 V.
► If the “LED3” LED is on, then the board is converting 5 V power to 3.3 V.
11.1.6 IRACS Addresses
LED43, 39, 40, 41 and 42 shown
LED41 illuminated
Each IRACS board has a unique address, shown in binary format via LED 39, 40, 41, 42, and 43. The
table represents vertically from top to bottom the order in which the LEDs should be illuminated. 1 means
the LED should be illuminated, 0 means the LED should be o󰀨.
NOTE No two IRACS boards should have the same order of LEDs illuminated.
