Removing the Craft Interface

To remove the craft interface, follow this procedure (see Figure 48):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. On the console or other management device connected to the master Routing Engine, enter CLI operational mode and issue the following command to shut down the router software. (If two Routing Engines are installed, also issue the command on the backup Routing Engine.)
   user@host> request system halt

   Note: Wait until a message appears on the console confirming that the operating system has halted.

   For more information about the command, see the JUNOS System Basics and Services Command Reference.

3. Power off the router by pressing the power switch for both power supplies to the OFF (0) position. On a DC power supply, the switch is located above the terminal studs on the power supply faceplate. On an AC power supply, the switch is just below the appliance inlet on the power supply faceplate.
4. 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.
5. Disconnect any external devices connected to the craft interface. For instructions, see Replacing Connections to Routing Engine Interface Ports.
6. Unscrew the thumbscrew at each end of the craft interface, using a Phillips screwdriver if necessary.
7. Pull the ends of the ejector levers, which are adjacent to the thumbscrews, away from the face of the craft interface.
8. Grasp the craft interface with both hands and slide it about halfway out of the chassis.
9. Place one hand underneath the craft interface to support it, slide it completely out of the chassis, and set it on the antistatic mat or in the electrostatic bag.
