Replacing an MX2000 CB-RE
Removing a CB-RE from an MX2000 Router
To remove a CB-RE:
You can remove the CB-RE as a unit.
Before removing a CB-RE, ensure that you know how to operate the ejector handles properly to avoid damage to the equipment.
Before you replace a CB-RE, you must take the host subsystem offline. If there is only one host subsystem, taking the host subsystem offline shuts down the router.
- Take the host subsystem offline.
- Place an electrostatic bag or antistatic mat on a flat, stable surface.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Open the ejector handles outward simultaneously to unseat the CB-RE.
- Grasp the ejector handles, and slide the CB-RE about halfway out of the chassis.
- Place one hand underneath the CB-RE to support it, and slide it completely out of the chassis.
- Place the CB-RE on the antistatic mat or into an antistatic bag.
- If you are not replacing the CB-RE immediately, install a blank panel over the empty slot.
Installing an MX2020 CB-RE
To install a CB-RE (see Figure 3):
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Take each CB-RE to be installed out of its electrostatic bag, and identify the slot on the CB-RE where it will be connected.
- Verify that each fiber-optic CB-RE has a rubber safety cap covering the transceiver. If it does not, cover the transceiver with a safety cap.
- Locate the slot in the CB-RE card cage in which you plan to install the CB-RE.
- Ensure that the CB-RE is right-side up, with the text on the faceplate of the CB-RE facing upward.
- Lift the CB-RE into place, and carefully align first the bottom, then the top of the CB-RE with the guides inside the card cage.
- Slide the CB-RE all the way into the card cage until you feel resistance.
- Grasp both ejector handles, and gently close them inward
simultaneously until the CB-RE is fully seated.

- Check the LEDs on the CB-RE faceplate to verify that it
is functioning normally.
The green
OK/FAILLED should light steadily a few minutes after the CB-RE is installed.If the
OK/FAILLED is red, remove and install the CB-RE again. If theOK/FAILLED still lights steadily, the CB-RE is not functioning properly. Contact your customer support representative. See Contacting Customer Support.
- Check the status of the CB-RE using the show chassis

Installing an MX2010 CB-RE
To install a CB-RE (seeFigure 4):
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Remove the CB-RE from the electrostatic bag.
- Carefully align the sides of the CB-RE with the guides inside the chassis.
- Slide the CB-RE into the chassis until you feel resistance, carefully ensuring that it is correctly aligned.
- Grasp both ejector handles, and gently close them inward simultaneously until the CB-RE is fully seated.
- Check the LEDs on the CB-RE faceplate to verify that it
is functioning normally.
The green
OK/FAILLED should light steadily a few minutes after the CB-RE is installed.If the
OK/FAILLED is red, remove and install the CB-RE again. If theOK/FAILLED still lights steadily, the CB-RE is not functioning properly. Contact your customer support representative. See Contacting Customer Support.
