Installing an M10i HCM
To install an HCM (see Figure 1 and Figure 2):
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Place one hand under the HCM to support it and grasp the handle on the faceplate with the other hand.
- Align the rear of the HCM with the guide rails
inside the chassis and slide it in completely.

Caution: Align the HCM carefully with the guide rails and push it in evenly. Damage can result if it gets lodged in the rails because of uneven movement.
- Place one hand under the Routing Engine to support it and grasp the handle on the faceplate with the other hand.
- Align the rear of the Routing Engine with the guide
rails inside the chassis and slide it in completely.

Caution: Align the Routing Engine carefully with the guide rails and push it in evenly. Damage can result if it gets lodged in the rails because of uneven movement.
- Tighten the thumbscrews on the Routing Engine faceplate to secure the Routing Engine.
- Issue the show chassis hardware command to verify that the HCM is functioning correctly.
