Disconnecting the Craft Interface Ribbon Cable from the Chassis Midplane

The craft interface communicates with the router through a ribbon cable that is attached to the original
top hat. Attached to the end of the ribbon cable is a female connector that plugs into a male connector
on the chassis midplane. The female connector contains a small mating clip on each of its sides. During
normal operation, the female connector is plugged inside the male connector and is held into place by the
mating clips. Figure 84 on page 297 shows the ribbon cable plugged into the male connector (viewed from
the front of the chassis).
The craft interface ribbon cable must be disconnected from the midplane connector before the top hat of
the chassis can be removed (as described in "Removing the Original Top Hat of the Chassis" on page 297).
To disconnect the ribbon cable from the chassis midplane, follow this procedure (see Figure 84 on page 297):
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
