Removing a TXP-F13 SIB

The TXP-F13 SIBs are located in the rear of the chassis in slots 0 through 15. Each TXP-F13 SIB weighs approximately 17.0 lb (7.7 kg).

TXP-F13 SIBs in active data switching planes are hot-pluggable. TXP-F13 SIBs in a spare data switching planes are hot-insertable and hot-removable. When you remove a TXP-F13 SIB in a spare switching plane, traffic forwarding continues without any degradation as long as the TXP-F13 SIBs in the other four switching planes remain in the chassis and online. When you remove a TXP-F13 SIB in an active switching plane, traffic forwarding continues without any degradation in the active switching planes. However, removing a TXP-F13 SIB in an active switching plane causes performance degredation in that switching plane. To avoid performance degredation, you can take the switching plane offline before you remove a TXP-F13 SIB.

To remove a TXP-F13 SIB (see Figure 1):

  1. Have ready an antistatic mat for the TXP-F13 SIB, and one dust cover for each fiber-optic array you remove from the TXP-F13 SIB.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Ensure the fiber-optic array cables connected to the TXP-F13 SIB are labeled so you can reconnect them correctly.
  4. Take the switching plane offline.

    See Taking a Switching Data Plane Offline.

  5. Use one of the following methods to take the TXP-F13 SIB offline:
    • Issue the request chassis sib f13 slot slot-number offline command. For example:

      user@host> request chassis sib f13 slot 6 offline

      For more information, see request chassis sib.

    • Press and hold the SIB ONLINE/OFFLINE button in the middle of the TXP-F13 SIB faceplate to take the TXP-F13 SIB offline. Press and hold the EVEN and ODD ONLINE/OFFLINE buttons on either side of the SIB ONLINE/OFFLINE button to take the connections to the TXP-T1600 SIBs offline. Hold the buttons down until all the LEDs on the faceplate are not lit.

  6. Remove each fiber-optic array cable (up to eight) from the TXP-F13 SIB. Warning

    Do not look directly into a fiber-optic array switching plane port or a connector at the end of a fiber-optic array cable connected to a port. The fiber optics emit laser light that can damage your eyes.

  7. Install a dust cover on each cable you removed from the TXP-F13 SIB. Align the dust cover with the cable and carefully press them together until they stop. The cover and the cable are keyed to ensure proper mating.
  8. Move the fiber-optic array cables to the side of the TXP-F13 SIB so they do not interfere with the removal of the TXP-F13 SIB. You might need to remove the cables from the cable management system.
  9. Simultaneously turn both ejector handles on the left and right of the faceplate counterclockwise to unseat the TXP-F13 SIB.
  10. Grasp both ejector handles, pull firmly, and slide the TXP-F13 SIB about three-quarters of the way out of the chassis.Caution

    Be prepared to support the weight of the TXP-F13 SIB (approximately 17.0 lb (7.7 kg)) before you slide it completely out of the chassis.

    When the TX-SIB is out of the chassis, do not hold it by its ejector handles or edge connectors. They cannot support its weight.

  11. Place one hand underneath the TXP-F13 SIB to support it and slide it completely out of the chassis. Place it on the antistatic mat.Caution

    Do not stack hardware components on one another after you remove them. Place each component on an antistatic mat resting on a stable, flat surface.

  12. If you are not reinstalling a TXP-F13 SIB into the emptied TXP-F13 SIB slot within a short time, install a blank TXP-F13 SIB panel over the slot to maintain proper airflow in the TXP-F13 SIB card cage.

To install a TXP-F13 SIB into the rear of the chassis (see Figure 2):

Caution

Be prepared to support the weight of the TXP-F13 SIB (approximately 17.0 lb (7.7 kg)) before you lift it.

  1. Have ready a replacement TXP-F13 SIB or TXP-F13 SIB blank panel.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Locate the slot in the TXP-F13 SIB card cage in which you plan to install the TXP-F13 SIB.
  4. Place one hand under the bottom edge of the TXP-F13 SIB and one hand around the top of the TXP-F13 SIB faceplate.Caution

    When the TXP-F13 SIB is out of the chassis, do not hold it by its ejector handles or edge connectors. They cannot support its weight.

  5. Lift the TXP-F13 SIB into place and carefully align the left and right edges with the guides inside the card cage.
  6. Carefully slide the TXP-F13 SIB all the way into the card cage until you feel resistance.
  7. Simultaneously turn both left and right ejector handles clockwise to seat the TXP-F13 SIB.
  8. Remove the dust cover from each TXP-F13 SIB fiber-optic array switching plane port.
  9. Remove the dust covers from the fiber-optic array cable connectors.
  10. Clean the fiber-optic array switching plane ports and cables.Caution

    While you replace a fiber-optic array cable, small deposits of oil, dust, and debris can enter the TXP-F13 SIB and TXP-T1600 SIB fiber-optic array switching plane ports, the fiber-optic array cables. We recommend that you clean the optics in these components, as well as the dust covers, immediately before connecting them.

  11. Connect each cable (up to eight) to its corresponding TXP-F13 SIB port. Align the cable with its corresponding TXP-F13 SIB port and carefully press it into the port until it stops. The cable and port are keyed to ensure proper mating. Note

    The optics in a fiber-optic array switching plane port are spring loaded, so you must continue to apply force to a fiber-optic array cable or loopback connector while securing it to a TXP-F13 SIB.

  12. Use one of the following methods to bring the TXP-F13 SIB online:
    • Press and hold the SIB ONLINE/OFFLINE button in the middle of the TXP-F13 SIB faceplate. The green OK LED should light steadily a few minutes after the TXP-F13 SIB is installed.

    • Issue the following CLI command:

      user@host> request chassis sib f13 slot slot-number online

      For more information, see request chassis sib.

  13. Verify that the TXP-F13 SIB is functioning normally:

    • Verify that the green OK LED is lit steadily.

    • Verify that the TXP-F13 SIB is online by issuing the show chassis sibs command.

      For more information, see show chassis sibs.
