Removing a Routing Engine

Caution: Before you replace a Routing Engine, you must power off the device. See Powering Off the Services Gateway.

To remove a Routing Engine (see Figure 48):

1. Power off the device. See Powering Off the Services Gateway.
2. Place an electrostatic bag or antistatic mat on a flat, stable surface.
3. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage.
4. Loosen the captive screws at each end of the Routing Engine faceplate.
5. Flip the ejector handles outward to unseat the Routing Engine.
6. Grasp the Routing Engine by the ejector handles and slide it about halfway out of the chassis.
7. Place one hand underneath the Routing Engine to support it and slide it completely out of the chassis.
8. Place the Routing Engine on the antistatic mat.

   Note: To maintain proper airflow through the chassis, do not leave an SCB installed in the chassis without a Routing Engine for extended periods of time. If a Routing Engine is removed, a replacement Routing Engine should be installed as soon as possible.
