Upgrading the PTX5000 FPCs

Preparing to Upgrade the FPCs in a PTX5000

When you upgrade a PTX5000 to use second-generation or third-generation FPCs, the forwarding capacity increases. See FPCs Supported on the PTX5000 for more information about the forwarding capacity for each type of FPC.

To prepare to upgrade the FPCs in a PTX5000:

  1. Ensure the site still meets the requirements—such as weight and power—when using the new components. See Overview of Preparing the Site for the PTX5000

  2. Determine the model numbers of the following components already installed:

    • SIBs

    • FPCs

    • Power distribution units (PDUs)

    • Power supply modules (PSMs)

  3. Ensure you have the required new components.

    • Up to eight FPCs

    • Nine SIBs

    • PDUs

    • PSMs

    • Fan trays

    Note:

    For the specific hardware requirements for each type of FPC, see PTX5000 FPC Upgrade Kit.

  4. Review all safety guidelines and warnings for the PTX5000.

    Warning:

    To avoid harm to yourself or the router as you install and maintain it, you must follow the safety procedures for working with Internet routers, as well as the guidelines and warnings for working with and near electrical equipment. However, providing an exhaustive set of guidelines for working with electrical equipment is beyond the scope of this documentation.

    See General Safety Guidelines and Warnings.

  5. Upgrade the software on the PTX5000.

Note:

To accommodate the change in the addressing scheme with eight Packet Forwarding Engines in the new FPC, you must upgrade the Junos OS on the PTX5000 to Junos OS Release 14.1. The upgrade to Junos OS Release 14.1 requires a reboot of the PTX5000.

Upgrading the FPCs in an Operational PTX5000

This topic describes the steps you take to upgrade your operational PTX5000 with new FPCs.

This topic does not describe the steps required to update an offline router with FPCs. See Upgrading the FPCs in an Offline PTX5000 for more information.

Note:

When upgrading to third-generation FPCs (see FPCs Supported on the PTX5000), be aware of the following:

  • When you are upgrading the FPCs on an operational PTX5000, make sure that the router is running Junos OS Release 15.1F5.

  • If the PTX5000 is running Junos OS Release 15.1F3 or 15.1F4, you must use the offline upgrade procedure. See Upgrading the FPCs in an Offline PTX5000.

Before you begin to upgrade:

  • Ensure that you understand how to prevent electrostatic discharge (ESD) damage.

  • Unpack the upgrade components and verify the parts received.

  • Gather the following tools required for the upgrade and integration:

    • Antistatic mat or antistatic bag for any components you remove from the chassis

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

    • ESD grounding wrist strap

    • Phillips (+) screwdriver, number 2

Warning:

To avoid harm to yourself or the PTX5000 as you install and maintain it, you must follow the safety procedures for working with Internet routers, as well as the guidelines and warnings for working with and near electrical equipment. However, providing an exhaustive set of guidelines for working with electrical equipment is beyond the scope of this documentation.

See General Safety Guidelines and Warnings.

To upgrade your operational PTX5000 with new FPCs follow these procedures:

Upgrading Junos OS on an Operational PTX5000

Upgrade Junos OS on the PTX5000 to the appropriate Junos OS Release for the FPC being upgraded to (see FPCs Supported on the PTX5000). For Junos OS upgrade information, see the Installation and Upgrade Guide.

Upgrading to the High Capacity Power System

The FPC that you are upgrading to might require you to upgrade your PTX5000 with the High Capacity power system. To determine whether an upgrade to the High Capacity power system is required, see PTX5000 FPC Upgrade Kit. To upgrade the power supply system, see Upgrading to the High Capacity DC Power System and Upgrading to the High Capacity AC Power System.

Upgrading the Horizontal Fan Tray

The FPC that you are upgrading to might require an upgraded horizontal fan tray. To determine wether an upgrade to the horizontal fan tray is required, see PTX5000 FPC Upgrade Kit. To upgrade the horizontal fan tray, see Replacing a PTX5000 Horizontal Fan Tray.

Removing and Replacing SIBs in an Operational PTX5000

To remove a SIB:

  1. Unpack the new SIBs and verify the parts received.
  2. Issue the following commands to verify the current state of the PTX5000, and the SIBs and FPCs currently installed in the system. If there are errors or alarms, do not proceed until you resolve the issues.
    • Use the show chassis alarms command to view the overall condition of the PTX5000. Resolve any alarms before proceeding.

    • show chassis fabric fpcs—Check the switch fabric links between the FPCs and the SIBs. The value of the Fabric management FPC state field in the command output should be Links ok. The Link error state indicates that the link between the SIB and FPC has CRC errors. However, the link is still eligible to carry traffic.

    • show chassis fabric sibs—Check the switch fabric links between the SIBs and FPCs. The value of the Fabric management SIB state field in the command output should be Links ok. The Link error state indicates that the link between the SIB and the FPC is not operational.

    Tip:

    If there are errors, the show chassis fabric topology command shows more details about the current fabric plane and link state. See Troubleshooting the PTX5000 Switch Interface Boards for more information.

  3. Reset the interface statistics by using the clear interfaces statistics all command so that you can easily determine whether any traffic drops are occurring during the procedure. Use the show interfaces statistics command to determine whether there are any errors.
  4. Include the fabric upgrade-mode default statement in the configuration of the PTX5000 at the [edit chassis] hierarchy level.
  5. Commit the configuration on both the primary and the backup Routing Engines.
  6. Use the show configuration chassis operational-mode command to verify that upgrade mode is set.
  7. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  8. To prevent damage to the equipment caused by static discharge, attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  9. Take one of the old SIBs offline by using the request chassis sib offline slot slot-number command. Leave the remaining SIBs online.
  10. Remove the offline SIB:
    1. Twist the ejector handles counterclockwise to unseat the SIB.
    2. Grasp both ejector handles, pull firmly, and slide the SIB about three-quarters of the way out of the chassis.
      Figure 1: Removing a SIB from the PTX5000Removing a SIB from the PTX5000
    3. 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.

  11. Install the new SIB:
    Figure 2: Installing a SIB into the PTX5000Installing a SIB into the PTX5000
    1. Attach an 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 faceplate.
    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. Twist the ejector handles clockwise until they stop.
  12. Bring the new SIB online by using the request chassis sib online slot slot-number command.
  13. When the new SIB is online, check for any link errors or traffic drops with the following commands:
    • show chassis alarms—Ensure there are no active alarms.

    • show chassis sibs —The value of the state field should be Online, indicating that the SIBs are operational and running.

    • show interfaces statistics and show pfe statistics traffic—Ensure that there are no traffic drops.

    Note:

    If link errors or traffic drops occur at any point during the upgrade, you can reverse the upgrade procedure and return the PTX5000 to its original state by taking the newly installed SIBs offline and replacing them with the original SIBs, one at a time. After the original SIBs are installed, use the commands listed above to verify that there are no longer any link errors or traffic drops. Finally, delete the fabric upgrade-mode default statement from the configuration of the PTX5000 at the [edit chassis] hierarchy level, and commit the configuration change.

  14. Repeat Step 9 through Step 13 until you have replaced each of the old SIBs with the new SIBs.
  15. Delete the fabric upgrade-mode default statement from the configuration of the PTX5000 at the [edit chassis] hierarchy level.
  16. Commit the configuration on both the primary and the backup Routing Engines.
  17. Check again for any issues with the following commands:
    • show chassis alarms

    • show chassis fabric fpcs

    • show chassis fabric sibs

    • show interfaces statistics and show pfe statistics traffic

Upgrading the FPCs in an Operational PTX5000

Before you begin upgrading the FPCs, use the show chassis hardware command to verify the following:

  • That the correct SIBs are installed.

  • That the correct PDUs and PSMs are installed.

  • That the correct fan trays are installed.

To determine which hardware is required for the FPC that you are upgrading to, see PTX5000 FPC Upgrade Kit.

To remove an existing FPC:

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  2. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Use one of the following methods to take the FPC offline:
    • Press and hold the FPC ONLINE/OFFLINE button. The green OK LED next to the button begins to blink. Hold the button down until the LED turns off.

    • Issue the following CLI command:

  4. Disconnect the cables from the PICs installed in the FPC. Immediately cover each transceiver and the end of each cable with a rubber safety cap. Arrange the disconnected cables in the cable management system, to prevent the cables from developing stress points.
    Warning:

    Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.

    CAUTION:

    Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

    CAUTION:

    Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

  5. If necessary, remove each installed PIC from the FPC.
  6. After you remove each PIC, immediately place it on an antistatic mat or in an electrostatic bag.
  7. Simultaneously turn both the ejector handles counterclockwise to unseat the FPC.
  8. Grasp the handles and slide the FPC straight out of the card cage halfway.
    Figure 3: Removing an FPC from the PTX5000Removing an FPC from the PTX5000
  9. Place one hand around the front of the FPC (the PIC housing) and the other hand under it to support it. Slide the FPC completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag. For detailed handling instructions, see Holding PTX5000 FPCs.
    CAUTION:

    The weight of the FPC is concentrated in the back end. Be prepared to accept the full weight—up to 50 lb (22.7 kg)—as you slide the FPC out of the chassis.

    When the FPC is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. These components cannot support its weight.

    Do not stack FPCs on top of one another after removal. Place each one individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.

  10. If you are not reinstalling an FPC into the emptied FPC slot within a short time, install a blank FPC panel over the slot to maintain proper airflow in the FPC card cage.
    CAUTION:

    After removing an FPC from the chassis, wait at least 30 seconds before reinserting it, installing another FPC in that slot, removing an FPC from a different slot, or inserting an FPC into a different slot.

To install an FPC:

CAUTION:

The FPC power connector is located in the corner where the bottom and the connector edges meet. If a power connector prong becomes bent, it no longer aligns with the socket connector on the midplane, and the FPC no longer functions.

  1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.

  2. Place the FPC on an antistatic mat.

  3. Take each PIC to be installed in the replacement FPC out of its electrostatic bag and identify the slot on the FPC where it will be installed.

  4. Verify that each fiber-optic transceiver has a rubber safety cap covering the transceiver. If it does not, cover the transceiver with a safety cap.

  5. Install each PIC into the appropriate slot on the FPC. See PTX Series PIC/FPC Compatibility for installing the supported PICs on the FPC. For information about installing a PIC, see the installation instructions in Replacing a PTX5000 PIC.

  6. Locate the slot in the FPC card cage in which you plan to install the FPC.

  7. Inspect the slot in the FPC card cage to verify that there are no missing or bent pins on the midplane.

  8. Inspect the FPC to verify that the connectors are not misaligned or damaged.

  9. Orient the FPC vertically with the component side facing to the right. Be sure the FPC is right-side up, with the components on the right of the FPC.

    CAUTION:

    When the FPC is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. These components cannot support its weight.

  10. Carefully align the connector edge of the FPC with the appropriate empty slot in the chassis.

  11. Lift the FPC into place and carefully align the bottom and top of the FPC with the guides inside the card cage.

    Figure 4: Installing an FPC into the PTX5000Installing an FPC into the PTX5000
  12. Gently rest the bottom edge of the FPC on the bottom edge of the slot opening, making contact a short distance forward of the power connector.

    CAUTION:

    Take care not to bend or otherwise damage the power connector prongs.

  13. Slowly slide the FPC into the slot until you feel resistance.

  14. Align the ejector handles on the FPC faceplate in a position close to horizontal.

  15. Simultaneously turn both ejector handles clockwise until you cannot turn them further.

  16. Remove the rubber safety cap from each fiber-optic transceiver and fiber-optic cable.

    Laser Warning:

    Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.

  17. Insert the appropriate cable into the cable connector ports on each PIC on the FPC. Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in a neatly coiled loop, using the cable management system. Placing fasteners on a loop helps to maintain its shape.

    CAUTION:

    Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.

    CAUTION:

    Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

  18. Use one of the following methods to bring the FPC online:

    • Press and hold the FPC ONLINE/OFFLINE button until the green OK LED next to the button begins to blink, in about 5 seconds.

    • Issue the following CLI command:

    CAUTION:

    After the OK LED lights steadily, wait at least 30 seconds before removing the FPC again, removing an FPC from a different slot, or inserting an FPC in a different slot.

  19. Verify that all the eight FPCs are installed properly and working by using the show chassis fpc command. The replaced FPCs are displayed as FPC E in the command output.

You can also verify correct FPC and PIC functioning by issuing the show chassis fpc and show chassis fpc pic-status commands, as described in Maintaining the PTX5000 FPCs.
