Replacing a TX-CIP

 

The TX-CIP is located to the left side of the TX-SIB card cage. The TX-CIP is hot-removable and hot-insertable. It weighs approximately 8 lb (3.6 kg). When the TX-CIP is removed, the backup TX-CIP provides redundant connections to the active host subsystem in the TX Matrix router and the active Control Boards in the T640 routers.

Note

If you are replacing a TX-CIP in an operational TX Matrix router, the TX Matrix router and each T640 router in the routing matrix must have redundant host subsystems.

Removing a TX-CIP

To remove a TX-CIP (see Figure 1):

  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. Label each cable with its corresponding port name—for example, LCC0, ETHERNET, CONSOLE, and RED ALARM.
  3. Disconnect all cables connected to the TX-CIP. For instructions, see Replacing a TX Matrix Console or Auxiliary Cable or Replacing a TX Matrix Management Ethernet Cable.
  4. Loosen the captive screws at the top and bottom of the TX-CIP faceplate.
  5. Grasp the handle on the TX-CIP faceplate and carefully pull the TX-CIP straight out of the chassis.Caution

    Be sure to slide the TX-CIP straight within the slot to avoid damaging the connector pins on the front of the midplane.

Installing a TX-CIP

To install a TX-CIP (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. Grasp the TX-CIP handle with one hand and hold the bottom edge of the TX-CIP with the other hand to support its weight.Note

    The components on the TX-CIP are on the left side of the board, unlike the components of a TX-SIB, which are on the right side. Verify that the components are on the left before inserting the TX-CIP.

  3. Insert the TX-CIP into its chassis slot, carefully aligning the top and bottom of the TX-CIP with the guides in the card cage.
  4. Carefully push the TX-CIP straight into the chassis until it contacts the midplane.Caution

    Be sure to slide the TX-CIP straight within the slot to avoid damaging the connector pins on the front of the midplane.

  5. Tighten the screws at the top and bottom of the TX-CIP faceplate.
  6. Using the labels to assist you, reattach all cables to the TX-CIP.
  7. To verify that the TX-CIP is installed correctly, plug an Ethernet cable into the ETHERNET port on the TX-CIP. If the host module is operational, the ACT LED blinks to indicate Ethernet activity. If you can run the CLI from a management device attached to the TX-CIP, the TX-CIP is installed correctly.
