Install and Remove PTX10008 Routing and Control Boards

 

The PTX10008 modular chassis can house one or two Routing and Control Boards (RCBs), depending on the configuration. You can install RCBs in either of the two top slots on the front of the chassis. After the hot insertion, the RCB powers up and comes online. In a single RCB systems, the RCB comes online as the master and restarts the line cards and the switch fabric. In a dual RCB system, the RCB powers up and comes online in the backup mode. To install or remove an RCB, read the following sections.

In redundant configurations, a PTX10008 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 router from shutting down.

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

To install an RCB:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to one of the ESD points on the chassis (see Figure 1).

  2. Either remove the cover from the available RCB slot (see Figure 2) or remove the failing RCB (see Remove a PTX10008 Routing and Control Board).

  3. Remove the new RCB from the antistatic 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 on the RCB and rotate them simultaneously clockwise until the RCB is fully seated and the handles are vertical (see Figure 3).

    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 PTX10008 Power Planning and Power Requirements for PTX10008 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 following CLI command:

    user@host> show chassis environment cb

Remove a PTX10008 Routing and Control Board

In redundant configurations, a PTX10008 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 router from shutting down. We recommend that you take base systems offline before replacing the RCB.

Before you remove a 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 master.

To remove a RCB:

  1. Take the RCB offline.

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

  2. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to one of the ESD points on the chassis (see Figure 4).

  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 5).

  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 immediately, install a cover in the empty slot.
