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). Four User LEDs (see figure 3-
4) and 16 STAT/ACT LEDs give status information for the base and fabric switches and their
links.
The LED push button toggles between the display of the base interface's and the fabric inter-
face's links. User LEDs 2 (base IF) and 4 (fabric IF) indicate which interface's links' status and
activity are currently displayed by the 16 STAT/ACT LEDs.
