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. Table 15 on page 38
