AT8901M User Guide

The LED number on the front plate indicates the logical ATCA slot (not the channel number) of
the connection. LED 1 for the base interface is the combined status/activity LED for both ShMC
links. If any of the two ShMC links is up, the LED is lit. If any of the links is active, the LED blinks.

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.
