Removing a Routing Engine | The Routing Engine is hot-pluggable. Follow the procedures in the applicable router hardware guide. Note: The M5/M10 routers have a cover over the Routing Engine. The M40e and M160 routers have a cover over all the rear chassis components. Remember to remove the screws (M5/M10, M20, M40e, and M160 routers) or captive screws (T320 router and T640 router) next to the ejector clips before you remove the Routing Engine. |
