Installing the Craft Interface

To install the craft interface, follow this procedure (see Figure 49):

1. Verify that the router is powered off. If necessary, halt the Routing Engine software and power off the power supplies as described in Removing the Craft Interface.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. Verify that the router is attached to a proper earth ground. For more information about ESD, see Preventing Electrostatic Discharge Damage.
3. Place one hand under the craft interface to support it and grasp one of the ejector levers at the front with the other hand.
4. Align the rear of the craft interface with the guides inside the chassis and slide it in completely.
5. Press the ejector lever at each end of the craft interface inward toward the faceplate.
6. Tighten the thumbscrew at each end of the craft interface faceplate until the craft interface is seated firmly in the chassis.
7. Reattach an external management device to one of the Routing Engine ports on the craft interface (AUX/MODEM, CONSOLE, or MGMT). If two Routing Engines are installed, connect to the Routing Engine that is configured to become the master, which by default is the Routing Engine in slot RE0. For more information, see Routing Engine. Also reattach alarm relay contacts if desired. For instructions, see Replacing Connections to Routing Engine Interface Ports.
