MX2020 Craft Interface Description
The craft interface allows the user to view status and troubleshooting information at a glance and to
perform many system control functions. It is hot-insertable and hot-removable.
An extended craft interface is also available for use with the extended cable manager. The extended craft
interface functions the same as the standard craft interface but provides additional clearance for
maintenance on the extended cable manager.
The craft interface is located on the front of the router above the upper fan tray and contains LEDs for
the router components, the alarm relay contacts, and alarm cutoff button.
Refer to Figure 11 on page
LEDs, buttons, and connectors for the craft interface.
