Maintaining MX10003 Routing and Control Board

 

Maintaining the Routing and Control Board (RCB)

Purpose

For optimum router performance, verify the condition of the RCB on regular basis.

Action

On a regular basis:

  • Check the LEDs on the front panel to view information about the status of the RCB.

  • To check the status of the Routing Engine on the RCB, issue the show chassis routing-engine command. The output is similar to the following:

    user@host> show chassis routing-engine

Replacing an MX10003 RCB

Removing an MX10003 RCB

The MX10003 host subsystem consists of two Routing and Control Boards (RCBs). The RCB is an integrated board and a single FRU that provides Routing Engine and Control Board functionality and supports virtualization.

To remove an RCB (see Figure 1):

Note

You can remove the RCB as a unit.

Caution

Before removing an RCB, ensure that you know how to operate the ejector handles properly to avoid damage to the equipment.

Caution

Before you replace an RCB, 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 handle outward to unseat the RCB.
  5. Grasp the ejector handle, and slide the RCB about halfway out of the chassis.
  6. Place one hand underneath the RCB to support it, and slide it completely out of the chassis.
  7. Place the RCB on the antistatic mat or into an antistatic bag.
  8. If you are not replacing the RCB immediately, install a blank panel over the empty slot.

Installing an MX10003 RCB

To install an MX10003 RCB (see Figure 2):

  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 RCB from the electrostatic bag.
  3. Carefully align the sides of the RCB with the guides inside the chassis.
  4. Slide the RCB into the chassis until you feel resistance, carefully ensuring that it is correctly aligned.
  5. Grasp the ejector handle, and gently close it inward simultaneously until the RCB is fully seated.
  6. Check the LEDs on the RCB faceplate to verify that it is functioning normally.
    • The green OK/FAIL LED should light steadily a few minutes after the RCB is installed.

    • If the OK/FAIL LED is red, remove and install the RCB again. If the OK/FAIL LED still lights steadily, the RCB is not functioning properly. Contact your customer support representative. See Contacting Customer Support.

  7. Check the status of the RCB by using the show chassis routing-engine command:
    user@host> show chassis routing-engine
