Replacing a T1600 TXP-LCC-3D SIB

 

Five SIBs are located in the rear of the chassis in the slots marked SIB0 through SIB4. The TXP-LCC-3D SIBs connect to the TXP-F13-3D SIBs in a TX Matrix Plus router.

TXP-LCC-3D SIBs in active data switching planes are hot-pluggable. TXP-LCC-3D SIBs in a spare data switching planes are hot-insertable and hot-removable. When you remove a TXP-LCC-3D SIB in a spare switching plane, traffic forwarding continues without any degradation as long as the other four switching planes remain online. However, removing a TXP-LCC-3D SIB in an active switching plane might cause performance degradation in that switching plane. To avoid performance degradation, you can take the switching plane offline before you remove a TXP-LCC-3D SIB. For more information, see the TX Matrix Plus Router Hardware Guide

Removing a T1600 TXP-LCC-3D SIB

Each TXP-LCC-3D SIB weighs approximately 9.4 lb (4.2 kg). To remove a TXP-LCC-3D SIB (see Figure 4):

  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 that the cables connected to the TXP-3D-LCC SIB are labeled so you can reconnect them correctly.
  4. Use one of the following methods to take the TXP-LCC-3D 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-LCC-3D SIB faceplate to take the SIB offline. Hold the buttons down until all the LEDs on the faceplate are not lit.

  5. Remove each switching plane cable from the SIB.
    • CXP—Disconnect the CXP cables (Figure 1) from the CXP transceivers. After all the CXP cables have been disconnected from the transceivers, remove the CXP transceivers (Figure 2) from the SIB.

      Warning

      Do not look directly into a CXP cable connected to a port. The fiber optics emit laser light that can damage your eyes.

    • AOC—Remove the AOC transceivers from the SIB (Figure 3).

  6. Install dust covers on the cables and transceivers that you removed. Align the dust cover with the cable or transceiver and carefully press them together until they stop. The dust cover and the cable or transceiver are keyed to ensure proper mating.
    • CXP—Install a dust cover on each CXP transceiver and CXP cable.

    • AOC—Install a dust cover on each AOC transceiver.

  7. Move the cables to the side of the SIB so they do not interfere with the removal of the SIB.
  8. Using a Phillips (+) screwdriver, number 2, loosen the captive screws 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 T4000 TXP-LCC-3D SIB

To install a TXP-LCC-3D SIB (see Figure 7):

  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 SIB to support it. With the other hand, hold one of the ejector handles on the SIB.
  3. Carefully align the sides of the SIB with the guides inside the chassis.
  4. Slide the SIB into the chassis, carefully ensuring that it is correctly aligned.
  5. Grasp both ejector handles, and press them inward to seat the 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 covers from the transceivers and cables. Store the dust covers in a dust-free resealable plastic bag.
  8. Insert the transceiver into the ports.
    • CXP—Insert the CXP transceivers into the TXP-LCC-3D ports. The CXP transceivers and the port are keyed to ensure proper mating. After all the CXP transceiver have been installed, reconnect each CXP cable (Figure 5) to the CXP transceiver in the TXP-LCC-3D port that corresponds to the label on the cable.

      Align the cable with the port and carefully press it into the port until it your hear a click and it stops. The CXP cables and CXP transceivers are keyed to ensure proper mating.

    • AOC—Using the cable labels, insert each AOC transceiver into its corresponding TXP-F13-3D port (Figure 6).

      Align the transceiver with the port and carefully press it into the port until it your hear a click and it stops. The AOC transceivers and the port are keyed to ensure proper mating.

  9. Bring the TXP-LCC-3D SIB online using one of the following methods:

    • Press and hold the ONLINE/OFFLINE button on the TXP-LCC-3D 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
  10. Check the LEDs on the TXP-LCC-3D SIB faceplate.
    • The green OK LED should light steadily a few minutes after the SIB is installed.

    • If the FAIL LED is lit steadily, remove and install the TXP-LCC-3D SIB again. Make sure that the SIB is seated properly. If the FAIL LED still lights steadily, the SIB is not functioning properly. Contact your customer support representative.

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

    If a SIB is not online, issue the request chassis sib online operational mode command.
