Maintaining QFX10000 Routing and Control Boards

 

Removing a QFX10000 Routing and Control Board

The QFX10000 line of modular chassis can have one or two Routing and Control Boards (RCBs), depending on the configuration. RCBs can be installed in either of the two top slots on the front of the chassis.

In redundant configurations, a QFX10000 RCB is a hot-removable and hot-insertable field-replaceable unit (FRU). In base configurations, you need to install a second RCB before removing a failing RCB in order to prevent the switch from shutting down. We recommend that you take base systems offline before replacing the RCB.

Before you remove an RCB, ensure that you have an electrostatic discharge (ESD) grounding strap.

Caution

In base configurations, removal of the RCB causes the system to shut down. In redundant configurations, removal of the RCB causes the system to reboot and start the election process for a new primary.

To remove an RCB:

  1. Take the RCB offline.

    Place an electrostatic bag or antistatic mat on a flat, stable surface.

  2. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis (see Figure 1 and Figure 2).

  3. Simultaneously rotate the RCB handles counterclockwise to unseat the RCB.
  4. Grasp the handles and slide the RCB about halfway out of the chassis (see Figure 3).

  5. Grasp each side of the RCB and slide it completely out of the chassis.
  6. Place the RCB on the antistatic mat.
  7. If you are not replacing the RCB now, install a cover in the empty slot.

Installing a QFX10000 Routing and Control Board

Before you install a RCB, ensure that you have an electrostatic discharge (ESD) grounding strap.

To install a RCB:

  1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the front of the chassis (see Figure 4 and Figure 5).

  2. Either remove the cover from the available RCB slot (see Figure 6) or remove the failing RCB (see Removing a QFX10000 Routing and Control Board).

  3. Remove the new RCB from the electrostatic bag and inspect it for any damage before installing it into the chassis.
  4. Lift the RCB by its sides, being careful not to bump the connectors.
  5. Carefully align the sides of the RCB with the guides inside the chassis.
  6. Slide the RCB into the chassis, carefully ensuring that it is correctly aligned.
  7. Grasp both handles and rotate them simultaneously clockwise until the RCB is fully seated and the handles are vertical (see Figure 7).

    The RCB begins the power-on sequence when fully seated.

  8. To verify that the RCB is functioning normally, check the PWR LED on its faceplate and the CONTROL BOARDS LED on the status panel. Both LEDs should light steadily shortly after the RCB is installed. If the PWR LED is blinking yellow, there might be insufficient power available. See Power Requirements for QFX10000 Components to ensure that you have adequate power for the additional unit.

    Another method of verifying that the RCB is online is to use the CLI command:
