The four front panel ATCA LEDs display the board’s health status.
It also provides 16 LEDs for status indication for the base and fabric interfaces. A switch allows
to select if the status information for the base or fabric interface is displayed. Four user LEDs
show information on which interface is selected to be displayed by the 16 link LEDs and on the
status of the base and fabric switches (see figure 3-5).
Each RJ45 displays the status of the link with the two integrated LEDs.
The reset switch will perform a reset on the CPU when pressed for less than 1 second and a
complete board reset (including IPMI) when pressed for more than 2 seconds.
