LINK/ACT indicator of an upper electrical port


Steady on: A link has been established on the port.

Blinking: The port is transmitting and receiving data.


LINK/ACT indicator of a lower electrical port


RUN/ALM: running status indicator


Steady on: The card is powered on. If the indicator is steady green for no more than 30 seconds, the CPU is being started. If the indicator is steady green for more than 30 seconds, the software is not running.

Slow blinking: The card software is running properly.

Fast blinking: The card software is starting.


Steady on: The card has failed and the fault requires manual intervention.
