Installing an MX104 Routing Engine
To install a Routing Engine (see Figure 44 on page 152):
1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2. Place one hand underneath the Routing Engine to support it.
3. Carefully align the sides of the Routing Engine with the guides inside the opening on
the chassis.
4. Slide the Routing Engine into the chassis until you feel resistance.
5. Tighten the captive screws on both sides of the Routing Engine.
6. Connect the management device cables to the Routing Engine.
NOTE: The Routing Engine might require several minutes to boot.
7. After the Routing Engine boots, verify that it is installed correctly:
•
Check the LEDs on the Routing Engine. If the router is operational and the Routing
Engine is functioning properly, the green ONLINE LED lights steadily. If the red
OK/FAIL LED lights steadily instead, remove and install the Routing Engine again.
If the red OK/FAIL LED still lights steadily, the Routing Engine is not functioning
properly. Contact your customer support representative.
•
Check the status of the Routing Engine, using the show chassis environment
