The four front panel ATCA LEDs (ATCA LEDs 1 to 3 and the Blue LED alongside the AMC slots)
display the board’s health and hotswap status (see table 3-17). LED1 of the User LEDs (see
figure 3-4) and the 16 STAT/ACT LEDs give status information for the base switch and its links.
User LED2 is always lit. The other two User LEDs and the LED push button do not have any
function.
