Installing an MX240 Routing Engine
To install a Routing Engine into an SCB (see Figure 91 on page 233):
1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2. Ensure that the ejector handles are not in the locked position. If necessary, flip the
ejector handles outward.
3. Place one hand underneath the Routing Engine to support it.
4. Carefully align the sides of the Routing Engine with the guides inside the opening on
the SCB.
5. Slide the Routing Engine into the SCB until you feel resistance, and then press the
Routing Engine's faceplate until it engages the connectors.
6. Press both of the ejector handles inward to seat the Routing Engine.
