Step 1: View the Craft Interface Status
Action
To view the craft interface status, look at the craft interface panel on the front of the router chassis. (See Figure 71 through Figure 76.)
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.
Alternative Action
You can view the craft interface information with the following CLI command:
user@host>show chassis craft-interfaceIf the craft interface fails, you can still view current craft interface information at the command line. A craft interface failure or removal generates a red alarm. See Viewing Craft Interface Information from the Command Line.
