Preparing to Upgrade the SIBs in an Operational T1600 Router

To prepare to integrate an operational T1600 router:

  1. Issue the show pfe statistics traffic command to verify the level of traffic. Verify that there are no fabric drops.
    show pfe statistics traffic
  2. Include the fabric upgrade-mode statement in the configuration of the TX Matrix Plus router at the [edit chassis] hierarchy level.
    user@host# set chassis fabric upgrade-mode
  3. Include the fabric upgrade-mode statement in the configuration of the T1600 router at the [edit chassis] hierarchy level.
    user@host# set chassis fabric upgrade-mode
  4. On both the TX Matrix Plus router and the T1600 router, verify that upgrade mode has been set.
    user@host# show chassis fabric upgrade-mode
  5. Commit the configuration on both the master and the backup Routing Engines.
    user@host# commit synchronize
  6. Display the status of the T1600 router SIBs by issuing the show chassis sibs command:
    user@host> show chassis sibs

    Verify that the T1600 router contains five SIBs (a requirement for integrating an operational T1600 router with the TX Matrix Plus router). Verify that four SIBs are in the Online state and one SIB is in the Spare state. To bring a SIB online, issue the request chassis sib online operational mode command. If needed, install additional SIBs. Use the installation procedure described in the T1600 Core Router Hardware Guide.

Upgrading a SIB in an Operational T1600 Router

Note

We recommend that you manage the system using a directly attached management device connected to the CONSOLE or AUXILIARY ports on the T1600 CIP instead of an out-of-band management device connected to the ETHERNET port. This provides you access to the system if its control plane is not functioning.

To upgrade a SIB:

  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. Take the spare SIB offline by using one of the following methods:
    • Press and hold the ONLINE/OFFLINE button on the SIB faceplate for about five seconds until the OK LED is not lit.

    • Issue the request chassis sib offline command. For example:

      user@host> request chassis sib offline slot 0
  3. Replace the spare SIB with a TXP-T1600 SIB. Use the replacement procedure described in Upgrading to TXP-T1600 SIBs in a T1600 Router (TXP-T1600 Configuration).Note

    After you replace a SIB with a TXP-T1600 SIB, do not replace another SIB in the T1600 router until you have successfully connected the TXP-T1600 SIB you just installed and verified operation of that switching plane.

    Note

    Do not bring the SIB online until instructed to do so.

  4. Issue the show chassis alarms command to display all alarms in the router.
    user@host> show chassis alarms

Connecting a Switching Plane in an Operational T1600 Router

The fiber-optic array cables should already be connected to the TXP-F13 SIBs on the TX Matrix Plus router. This procedure connects the fiber-optic array cables to the TXP-T1600 SIBs in the T1600 router (four for each TXP-T1600 SIB). To connect the switching planes:

  1. Gather the tools required for the upgrades and integration.
    • Phillips (+) screwdriver, number 2

    • Dust-free resealable plastic bags for temporary storage of TXP-T1600 SIB port dust covers

    • Electrostatic discharge (ESD) grounding wrist strap

  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. Use the labels on the ends of the fiber-optic array cables and Table 1 to identify the cable that plugs into the TXP-T1600 SIB ports labeled A, B, C, and D.
  4. Remove the dust cover from the TXP-T1600 SIB port. Store the dust cover in a dust-free resealable plastic bag.Caution

    If you do not use dust covers, small deposits of oil, dust, and debris can enter the portss and cable connectors. If a dust cover is missing from a port or cable, clean it before you connect the cable.

  5. Remove the dust covers from the four fiber-optic array cable connectors that connect to one TXP-T1600 SIB. Store the dust covers in a dust-free resealable plastic bag.
  6. Align the cable connectors labeled A, B, C, and D with the corresponding TXP-T1600 SIB port, and carefully press each cable connector into the port until it stops. The cable connectors and TXP-T1600 SIB ports are keyed to ensure proper mating.
  7. Optionally, you can route the cables into the rear cable management system. Pull the latch for the cable management clamp toward you to release it. Place the fiber-optic array cable upward into one the cable slots. Route the cable upward toward the 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.

  8. Arrange the fiber-optic array cables so that they do not interfere with system airflow and maintenance access.
  9. Bring the TXP-T1600 online by using one of the following methods:
    • Press and hold the ONLINE/OFFLINE button on the SIB faceplate for about five seconds until the OK LED is lit.

    • Issue the request chassis sib online command. For example:

      user@host> request chassis sib online slot 0
  10. On the T1600 router, verify the TXP-T1600 SIB LEDs.
    • Verify that the OK LED is lit steadily green.

    • Verify that the RxPWR LED for each port is lit steadily green. If a RxPWR port LED is yellow or red, clean the fiber-optic port and fiber optic array cables again. If the LEDs continue to be yellow or red after cleaning, contact your customer support representative for additional instructions. Do not proceed with the upgrade until you have spoken to your customer support representative.

  11. On the TX Matrix Plus router, verify the TXP-F13 SIB LEDs
    • Verify that the OK is lit steadily green.

    • Verify that the RxPWR LED for each port is lit steadily green. If a RxPWR port LED is yellow or red, clean the fiber-optic port and fiber optic array cables again. If the LEDs continue to be yellow or red after cleaning, contact your customer support representative for additional instructions. Do not proceed with the upgrade until you have spoken to your customer support representative.

  12. From the TX Matrix Plus router, issue the request chassis sib F13 train-link-receive slot command, where slot corresponds to the slot location of each TXP-F13 installed 0, 3, 6, 8, or 11. For example:
    user@host> request chassis sib F13 train-link-receive slot 0
  13. From the T1600 router, issue the request chassis sib train-link-receive slot command, where slotcorresponds to the slot location of each TXP-T1600 SIB installed 0, 1, 2, 3, or 4. For example:
    user@host> request chassis sib train-link-receive slot 0
  14. From the TX Matrix Plus router, issue the request chassis sib F13 train-link-transmit slot command, where slot corresponds to the slot location of each TXP-F13 installed 0, 3, 6, 8, or 11. For example:
    user@host> request chassis sib F13 train-link-transmit slot 0
  15. From the T1600 router, issue the request chassis sib train-link-transmit slot command, where slot corresponds to the slot location of each TXP-T1600 SIB installed 0, 1, 2, 3, or 4. . For example:
    user@host> request chassis sib train-link-transmit slot 0
  16. On the T1600 router, verify that the LINK and RxPWR port LEDs for each port and the OK and ACTIVE TXP-T1600 LEDs are lit steadily green.
  17. On the TX Matrix Plus router, verify that the LINK and RxPWR port LEDs for each port and the OK and ACTIVE TXP-F13 LEDs are lit steadily green. If the LEDs are not steadily lit green, contact your customer support representative for additional instructions. Do not proceed with the upgrade until you have spoken to your customer support representative.
  18. Issue the show chassis alarms command to display all alarms in the router.
    user@host> show chassis alarms
  19. Bring an active T1600-SIB offline by using one of the following methods:
    • Press and hold the ONLINE/OFFLINE button on the SIB faceplate for about five seconds until the OK LED is lit.

    • Issue the request chassis sib online command. For example:

      user@host> request chassis sib offline slot 1
  20. Display the status of the T1600 router SIBs by issuing the show chassis sibs command:
    user@host> show chassis sibs

    Verify that four SIBs are in the Online state and one SIB is in the Spare state.

    If show chassis sibs shows that any SIB is in the Check state, issue the show pfe statistics traffic command to verify the level of traffic. Verify that there are no fabric drops. If there are fabric drops, contact your customer support representative for additional instructions. Do not proceed with the upgrade until you have spoken to your customer support representative.

    show pfe statistics traffic
  21. Repeat the procedure for the remaining SIBs.
