Install and Remove PTX10004 Routing and Control Boards

The PTX10004 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 system, the RCB comes online as the primary 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.

How to Hold a Routing and Control Board

Pay proper attention to the way you are holding an RCB. An RCB is installed horizontally, and it is best to hold it by the sides of the unit when it isn’t in the chassis.

To handle and store an RCB properly:

  1. Orient the RCB so that the faceplate is toward you.
  2. Grasp each side of the unit firmly as you slide the unit out of the chassis.
  3. Take care not to strike the unit against any object as you carry it.
    CAUTION:

    Never hold the RCB by the connector edge. The connectors are fragile and the RCB will not seat properly if the connector is damaged.

  4. If you must rest an RCB on an edge, place a cushion between the edge and the surface.
    CAUTION:

    Do not stack RCBs on top of one another or on top of any other component.

  5. Place each RCB in an individual antistatic bag or separately on an antistatic mat that is placed on a flat, stable surface.

How to Store a Routing and Control Board

You must store an RCB either in the chassis or in a spare shipping container, horizontally and sheet-metal side down. Do not stack these units on top of one another or on top of any other component. Place each unit separately in an antistatic bag or on an antistatic mat placed on a flat, stable surface.

Note:

Because these units are heavy, and because antistatic bags are fragile, inserting the line card into the bag is best done by two people.

To insert an RCB into an electrostatic bag:

  1. Hold the unit horizontally with the faceplate toward you.
  2. Have the second person slide the opening of the antistatic bag over the connector edge and then pull the bag to cover the unit.

If you must insert an RCB into a bag by yourself:

  1. Lay the unit horizontally on an antistatic mat that is on a flat, stable surface with the sheet-metal side down.

  2. Orient the unit with the faceplate toward you.

  3. Carefully insert the connector edge into the opening of the bag and pull the bag toward you to cover the unit.

Install a PTX10004 Routing and Control Board

In redundant configurations, a PTX10004 RCB is a hot-removable and hot-insertable field-replaceable unit (FRU). In base configurations, you need to install a second RCB before you remove a failing RCB 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 PTX10004 Routing and Control Board).

  3. Remove the new RCB from the antistatic bag and inspect it for any damage before installing it in 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 PTX10004 Power Planning and Power Requirements for PTX10004 Components to ensure that you have adequate power for the additional unit.

    Another method to verifyi that the RCB is online is to use the following CLI command:

Remove a PTX10004 Routing and Control Board

In redundant configurations, a PTX10004 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 to prevent the router 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. Place an antistatic bag or antistatic mat on a flat, stable surface.
  2. Use the following CLI commands to take the RCB offline (re0 or re1).

    You can use the show chassis environment cb | match State CLI command to verify that the RCB is offline.

    For example, your primary RCB is re0 and your backup RCB is re1 and you want to remove the backup RCB from the chassis. You would issue the above commands from the console of the primary RCB. On the console of the backup, you would see output similar to the following:

  3. 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).

  4. Simultaneously rotate the RCB handles counterclockwise to unseat the RCB.
  5. Grasp the handles and slide the RCB about halfway out of the chassis (see Figure 5).

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