Replacing an MX2000 CB-RE

Removing a CB-RE from an MX2000 Router

To remove a CB-RE:

Note:

You can remove the CB-RE as a unit.

CAUTION:

Before removing a CB-RE, ensure that you know how to operate the ejector handles properly to avoid damage to the equipment.

CAUTION:

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.

  1. Take the host subsystem offline.
  2. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  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.
  4. Open the ejector handles outward simultaneously to unseat the CB-RE.
  5. Grasp the ejector handles, and slide the CB-RE about halfway out of the chassis.
  6. Place one hand underneath the CB-RE to support it, and slide it completely out of the chassis.
  7. Place the CB-RE on the antistatic mat or into an antistatic bag.
  8. 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):

  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. 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.
  3. 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.
  4. Locate the slot in the CB-RE card cage in which you plan to install the CB-RE.
  5. Ensure that the CB-RE is right-side up, with the text on the faceplate of the CB-RE facing upward.
  6. 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.
  7. Slide the CB-RE all the way into the card cage until you feel resistance.
  8. Grasp both ejector handles, and gently close them inward simultaneously until the CB-RE is fully seated.

  9. 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 Contact Customer Support.

Installing an MX2010 CB-RE

To install a CB-RE (seeFigure 4):

  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 Contact Customer Support.
