Understanding the Craft Interface
Purpose Inspect the craft interface to ensure that you can monitor the status of the router
and perform system management functions. The craft interface is also referred to
as the Front Panel Module (FPM).
What Is the Craft
Interface
The craft interface, located on the front of the router chassis, provides status
information, alarm indicators and contacts, Physical Interface Card (PIC) online and
offline buttons, Flexible PIC Concentrator (FPC) online and offline buttons and LED
status indicators, Routing Engine offline button and LED status indicators, and
management access to the router.
You can display craft interface status information from the JUNOS software CLI.
The craft interface is hot-removable and hot-insertable. You can remove and replace
it without powering down the router or disrupting routing functions.
For detailed information about how the router craft interface works, see the
appropriate router hardware guide.
