What It Means The command output displays the information that is currently displayed on the
craft interface, including the alarm indicator status, the component status, and the
alarm messages currently displayed on the LCD display. The command output is for
an M20 router. A craft interface failure generates a red alarm, and you see an
fpx0:

alarm in the LCD screen output. The fpx0 interface or the Ethernet
management interface provides an out-of-band method of connecting to the router
from the craft interface.
Verifying Craft Interface Failure
When the craft interface fails, you might not see any lights on the craft interface
panel and the LCD display will be blank. In addition, the buttons on the panel might
not work as indicated.
On M5 and M10 routers, you can use the lamp test button to ensure that the alarm
LED lights are working properly.
