Removing the Routing Engine
To remove the Routing Engine from the chassis:
1. On the external management device connected to the Routing Engine, shut down the
host subsystem by using the request system power-off command.
2. Wait until a message appears on the console confirming that the operating system
has halted.
3. Remove the cables connected to the Routing Engine.
4. Place an electrostatic bag or antistatic mat on a flat, stable surface. Attach an ESD
grounding strap to your bare wrist and connect the strap to one of the ESD points on
the chassis.
5. Verify that the Routing Engine LEDs are off. Loosen the captive screws on the top and
bottom of 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. Place the Routing Engine on the antistatic mat.
NOTE: To maintain proper airflow through the chassis, do not leave an SCB
installed inthe 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.
