Removing the Routing Engine
To remove the backup Routing Engine from the chassis (see
and Figure 188 on page
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 electrostatic discharge
(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 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.
