Removing a TXP-T1600 SIB

Five SIBs are installed in the router. The SIBs are located in the rear of the chassis in the slots marked SIB0 through SIB4. Each TXP-T1600 SIB weighs 10.2 lb (4.6 kg).

To remove the TXP-T1600 SIBs (see Figure 1):

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  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 to the TXP-T1600 SIB are labeled so you can reconnect them correctly.
  4. Use one of the following methods to take the TXP-T1600 SIB offline:
    • Issue the request chassis sib lcc number slot slot-number offline command. For example:

      user@host> request chassis sib lcc 0 slot 3 offline
    • Press and hold the SIB ONLINE/OFFLINE button in the middle of the TXP-T1600 SIB faceplate to take the SIB offline. Hold the buttons down until all the LEDs on the faceplate are not lit.

  5. Remove all four fiber-optic array cables from the TXP-T1600 SIB. Warning

    Do not look directly into a fiber-optic array 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.

  6. Install a dust cover on each cable you removed from the TXP-T1600 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.
  7. Move the fiber-optic array cables to the side of the TXP-T1600 SIB so they do not interfere with the removal of the TXP-T1600 SIB.
  8. Loosen the captive screws (using a Phillips (+) screwdriver, number 2) on the ejector handles on each side of the SIB faceplate.
  9. Flip the ejector handles outward to unseat the SIB.
  10. Grasp both ejector handles, pull firmly, and slide the SIB about three-quarters of the way out of the chassis.
  11. Place one hand underneath the 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.

Installing a TXP-T1600 SIB

Each TXP-T1600 SIB weighs approximately 10.2 lb (4.6 kg). To install a TXP-T1600 SIB (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. Place one hand underneath the TXP-T1600 SIB to support it. With the other hand, hold one of the ejector handles on the TXP-T1600 SIB faceplate.
  3. Carefully align the sides of the TXP-T1600 SIB with the guides inside the chassis.
  4. Slide the TXP-T1600 SIB into the chassis, carefully ensuring that it is correctly aligned.
  5. Grasp both ejector handles and press them inward to seat the TXP-T1600 SIB. Ensure that the ejector handle tabs are properly mated inside their corresponding chassis slots. You might have to close and open the handles a few times before the tabs catch the slots.
  6. Tighten the captive screws on the ejector handles.
  7. Remove the dust cover from covering each TXP-F13 SIB fiber-optic array port.
  8. Remove the dust covers from the fiber-optic array cable connectors.
  9. Clean the fiber-optic array 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 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.

  10. Connect each cable to its corresponding TXP-T1600 port. Align the cable with its corresponding TXP-T1600 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 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-T1600 SIB.

  11. Bring the TXP-T1600 SIB online using one of the following methods:

    • Press and hold the ONLINE/OFFLINE button on the TXP-T1600 SIB faceplate. The green OK LED on the faceplate begins to blink. Hold the button down until the LED blinks.

    • Issue the following CLI command on the router:

      user@host> request chassis sib online slot 0

Verifying the Installation of a TXP-T1600 SIB

To verify that the TXP-T1600 is functioning normally:

  1. Check the LEDs on the TXP-T1600 faceplate. A few minutes after the TXP-T1600 is installed:
    • The green OK LED should light steadily, indicating that the TXP-T1600 SIB is installed correctly.

    • The green LINK port LED should light steadily, indicating that the link between the TXP-F13 SIB port and the TXP-T1600 SIB port has been established successfully.

    • The green RxPWR port LED should light steadily, indicating that full optical power is being received.

    • The green OK LED should light steadily a few minutes after the TXP-T1600 is installed.

    • If the FAIL LED is lit steadily, remove and install the TXP-T1600 again. Make sure that the TXP-T1600 is seated properly. If the FAIL LED still lights steadily, the TXP-T1600 is not functioning properly. Contact your customer support representative.

  2. Verify that four TXP-T1600s are in the Online state and one SIB is in the Spare state. Display the status of the TXP-T1600 by issuing the show chassis sibs command:
    user@host> show chassis sibs

    To bring a TXP-T1600 online, issue the request chassis sib online operational mode command.
