Connecting Offline SIBs While Performing Operational Upgrades with 3D SIBs

 

While performing an operational upgrade you must connect offline SIBs one switch fabric plane at a time. This topic describes the steps to follow in these circumstances. This topic applies to the following scenarios:

TXP-F13-3D and TXP-LCC-3D SIBs use active optical cables (AOCs) with integrated transceivers or CXP transceivers and CXP cables to interconnect the SFC and LCCs.

Before you begin connecting cables to the offline SIBs:

Each TXP-F13-3D SIB has 16 ports labeled 0 through 15. Each TXP-LCC-3D SIB has 8 ports labeled 0 through 7. To connect cables to the offline switch fabric plane SIBs, perform one of the following procedures, depending on which types of cables you are using:

Connecting Offline TXP-F13-3D and TXP-LCC-3D SIBs By Using Active Optical Cables

To connect offline TXP-F13-3D and TXP-LCC-3D SIBs by using AOCs:

  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. Make sure that both ends of the AOC are labeled so that you can easily identify which ports you are connecting. (See Switching Plane Connections Between TXP-F13-3D SIBs and TXP-LCC-3D SIBs.)
  3. Identify the TXP-F13-3D SIB port that corresponds to the label you attached to the end of the AOC.
  4. Remove the dust cover from the AOC transceiver (see Figure 1) that you plan to connect to the TXP-F13-3D SIB port. Store the dust cover in a dust-free resealable plastic bag.

  5. Insert the AOC transceiver into the TXP-F13-3D SIB port. Align the transceiver with the TXP-F13-3D SIB port, and carefully press the transceiver into the port until you hear a click and it stops. The transceiver and port are keyed to ensure proper mating.
  6. Route the cable through the cable management system.

    1. Pull the latch for the cable management clamp toward you to release it.
    2. Place the switching plane cable into the cable management system.
    3. Route the cable upward toward the comb assembly on top of the chassis, and press it into the divider.
    Caution

    You must maintain a minimum bend radius of 4 in. (10.2 cm) short term, and 3 in. (7.6 cm) long term.

  7. Route the AOC to the LCC, using the attached label to identify the correct LCC. (See Switching Plane Connections Between TXP-F13-3D SIBs and TXP-LCC-3D SIBs.)
  8. Identify the TXP-LCC-3D SIB port that corresponds to the label you attached to the end of the AOC.
  9. Remove the dust cover from the AOC transceiver (see Figure 1) that you plan to connect to the TXP-F13-3D SIB port. Store the dust cover in a dust-free resealable plastic bag.
  10. Insert the AOC transceiver into the TXP-LCC-3D SIB port. Align the transceiver with the TXP-LCC-3D SIB port, and carefully press the transceiver into the port until you hear a click and it stops. The transceiver and port are keyed to ensure proper mating.
  11. Arrange the switching plane cables so that they do not interfere with system airflow and maintenance access.

    For an illustration of airflow through the SFC, see TX Matrix Plus Cooling System Description.

  12. Repeat the procedure for the remaining switching plane cables that connect to the TXP-F13-3D and TXP-LCC-3D SIBs in the offline switch fabric plane.

Connecting Offline TXP-F13-3D and TXP-LCC-3D SIBs By Using CXP Transceivers and CXP Cables

To connect offline TXP-F13-3D and TXP-LCC-3D SIBs by using CXP transceivers and CXP cables:

  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. Make sure that both ends of the CXP cable are labeled so that you can easily identify which ports you are connecting. (See Switching Plane Connections Between TXP-F13-3D SIBs and TXP-LCC-3D SIBs.)
  3. Using the labels you created for the switching plane cables, identify which cable will be connected to each TXP-F13-3D SIB port. See Labeling the TX Matrix Plus Switching Plane Cables.
  4. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  5. Identify the TXP-F13-3D SIB port that corresponds to the label you attached to the end of the CXP cable.
  6. Remove the dust cover from a CXP transceiver (see Figure 2). Store the dust cover in a dust-free resealable plastic bag.

  7. Insert the CXP transceiver into the TXP-F13-3D SIB port.
  8. Remove the dust cover from one end of the CXP cable (see Figure 3). Store the dust cover in a dust-free resealable plastic bag.

  9. Insert the CXP cable into the CXP transceiver. Align the cable connector with the transceiver, and carefully press the cable into the transceiver until you hear click and it stops. The cable and transceiver are keyed to ensure proper mating.
  10. Route the cable through the cable management system.

    1. Pull the latch for the cable management clamp toward you to release it.
    2. Place the switching plane cable into the cable management system.
    3. Route the cable upward toward the comb assembly on top of the chassis, and press it into the divider.
    Caution

    You must maintain a minimum bend radius of 4 in. (10.2 cm) short term, and 3 in. (7.6 cm) long term.

  11. Route the CXP cable to the LCC, using the attached label to identify the correct LCC. (See Switching Plane Connections Between TXP-F13-3D SIBs and TXP-LCC-3D SIBs.)
  12. Identify the TXP-LCC-3D SIB port that corresponds to the label you attached to the end of the CXP cable.
  13. Remove the dust cover from a CXP transceiver (see Figure 2). Store the dust cover in a dust-free resealable plastic bag.
  14. Insert the CXP transceiver into the TXP-LCC-3D SIB port.
  15. Remove the dust cover from one end of the CXP cable (see Figure 3). Store the dust cover in a dust-free resealable plastic bag.
  16. Insert the CXP cable into the CXP transceiver. Align the cable connector with the transceiver, and carefully press the cable into the transceiver until you hear a click and it stops. The cable and transceiver are keyed to ensure proper mating.
  17. Arrange the switching plane cables so that they do not interfere with system airflow and maintenance access.

  18. Repeat the procedure for the remaining switching plane cables that connect to the TXP-F13-3D and TXP-LCC-3D SIBs in the offline switch fabric plane.
