Installing an MX2010 CB-RE
To install a CB-RE (see Figure 185 on page 403 ):
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
2. Remove the CB-RE from the electrostatic bag.
3. Carefully align the sides of the CB-RE with the guides inside the chassis.
4. Slide the CB-RE into the chassis until you feel resistance, carefully ensuring that it is correctly aligned.
5. Grasp both ejector handles, and gently close them inward simultaneously until the CB-RE is fully seated.
6. Check the LEDs on the CB-RE faceplate to verify that it is functioning normally.
•
The green OK/FAIL LED should light steadily a few minutes after the CB-RE is installed.
•
If the OK/FAIL LED is red, remove and install the CB-RE again. If the OK/FAIL LED still lights steadily,
the CB-RE is not functioning properly. Contact your customer support representative. See “Contacting
Customer Support” on page 731 .
7. Check the status of the CB-RE by using the show chassis environment cb command:
