Meaning The command output displays the router system operation status for an M160 router,
including the alarm indicators, the information displayed on the craft interface LCD
display, and the component LEDs. An asterisk (*) indicates that the component is
operating normally. A dot is merely a placeholder, and indicates nothing. For example,
the asterisks in the Host Front Panel System LEDs section indicate that the Routing Engine
in slot 1 is operating normally and that it is the master. The dots in the Front Panel Alarm
Indicators section indicate that there are no system alarms.
NOTE: Physically look at the router craft interface. The router name in the
LCD display helps verify that you have located the correct router to monitor.
