Upgrading an Operational TX Matrix Plus Routing Matrix to 3D SIBs

 

This topic describes the steps you take to upgrade your operational TX Matrix Plus routing matrix to 3D SIBs. During the operational upgrade the TX Matrix Plus switch-fabric chassis (SFC) and up to four attached T1600 line-card chassis (LCCs) are upgraded simultaneously. If you plan to later attach additional LCCs, they must be integrated into the routing matrix while they are powered off.

Note

This topic does not describe the steps required to integrate an operational standalone router into a TX Matrix Plus routing matrix with 3D SIBs. See Upgrading an Operational Standalone Router and Integrating It into a TX Matrix Plus Routing Matrix with 3D SIBs for more information.

Before you begin to upgrade an operational TX Matrix Plus routing matrix to 3D SIBs:

  • Perform the tasks described in Preparing to Upgrade an Operational TX Matrix Plus Routing Matrix to 3D SIBs.

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

  • Unpack the upgrade components and verify the parts received.

  • Gather the tools required for the upgrades 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

    • Electrostatic discharge (ESD) grounding wrist strap

    • Phillips (+) screwdriver, number 2

To upgrade your operational TX Matrix Plus routing matrix to 3D SIBs:

  1. Upgrading the Junos OS on the TX Matrix Plus Routing Matrix

  2. Removing and Replacing FRUs in the TX Matrix Plus Routing Matrix

  3. Preparing to Upgrade the Switch Fabric on the TX Matrix Plus Routing Matrix

  4. Upgrading the Switch Fabric Planes on the TX Matrix Plus Routing Matrix

  5. Completing the Upgrade and Restarting the TX Matrix Plus Routing Matrix

Upgrading the Junos OS on the TX Matrix Plus Routing Matrix

Upgrade the Junos OS on the SFC and attached LCCs to 64-bit Junos OS Release 13.2 or later.

See Upgrading the Junos OS on a Routing Matrix with a TX Matrix Plus Router for more information.

Note

The SFC and LCCs must each contain two host subsystems. All host subsystems must be running the same Junos OS release. This is a requirement for graceful switchover.

After confirming that the new packages are successfully installed and running, issue the request system snapshot all-chassis command to back up the new software.

See request system snapshot for more information.

Removing and Replacing FRUs in the TX Matrix Plus Routing Matrix

Depending on your hardware configuration, you might need to remove or replace FRUs in the SFC and attached LCCs. See Line-Card Chassis Component Overview for information about the required hardware, and Upgrade Kits for TX Matrix Plus Routers and Line-Card Chassis for information about the upgrade kits that can be purchased.

  1. Remove unsupported FPCs and PICs from the T1600 LCC. The following FPCs are not supported in a TX Matrix Plus routing matrix with 3D SIBs:
    • T640-FPC1-E and T640-FPC1-E2

    • T640-FPC2, T640-FPC2-E, and T640-FPC2-E2

    • T640-FPC3, T640-FPC3-E, and T640-FPC3-E2

    See Removing a T1600 FPC for more information.

  2. Install two six-input DC power supplies (model number PWR-T-6-60-DC) in each LCC. See Upgrading the Line-Card Chassis Power Supplies for more information.
  3. Upgrade the rear fan tray (model number FAN-R-TXP-3D-LCC) in each LCC. See Upgrading the Line-Card Chassis Rear Fan Tray for more information.
  4. If you are upgrading from a T640 router or T16000 router, upgrade the two front fan trays (model number FANTRAY-T4000) in each LCC. See Upgrading to a T4000 Upper Front Fan Tray in the T1600 Router and Upgrading to a T4000 Lower Front Fan Tray in the T1600 Router for more information.
  5. Upgrade the front air filter cover on the SFC. Refer to the air filter cover replacement procedure described in Upgrading the TX Matrix Plus Left Front Air Filter Coverfor more information.
  6. (Optional) Upgrade the rear cable management system (model number CBL-MGR-TXP-3D-LCC) in each LCC. See Installing the Line-Card Chassis Rear Cable Management System for more information.

Preparing to Upgrade the Switch Fabric on the TX Matrix Plus Routing Matrix

Before you begin upgrading the switch fabric on the TX Matrix Plus routing matrix, you must perform the following steps:

  1. Delete unsupported configurations from the TX Matrix Plus routing matrix configuration.

    For any configured CoS schedulers, the non-tcp and tcp options are not supported in the protocol statement. Only the any protocol option is supported in the statement below:

  2. Include the fabric upgrade-mode 3d-fabric statement in the configuration of the TX Matrix Plus routing matrix at the [edit chassis] hierarchy level.
    user@host# set fabric upgrade-mode 3d-fabric


  3. Commit the configuration.
    user@host# commit


    Caution

    During the commit process Junos OS will verify the compatibility of the TX Matrix Plus routing matrix hardware. Correct any errors before proceeding to the next step.

  4. Issue the show chassis fabric plane command to determine which switch fabric plane is operating as the spare, or standby, switch fabric plane. There are five switch fabric planes, numbered 0 through 4. One switch fabric plane operates as the spare switch fabric plane. The other four switch fabric planes are normally online, indicating that they are operational. In the following example, switch fabric plane 0 on the SFC and SIB 0 on the LCC are Spare, indicating that switch fabric plane 0 is the standby switch fabric plane. The remaining switch fabric planes on the SFC and SIBs on the LCC are Online:
    user@host> show chassis fabric plane


    Caution

    If one or more switch fabric planes are offline, or if other errors are indicated, use the procedures described in Troubleshooting the TX Matrix Plus TXP-F13 and TXP-F2 SIBs to try to resolve any problems. Do not proceed to the next step until the issues are resolved.

Upgrading the Switch Fabric Planes on the TX Matrix Plus Routing Matrix

You must upgrade one switch fabric plane at a time. You will perform this procedure for each switch fabric plane. To upgrade a switch fabric plane:

  1. Issue the request chassis fabric plane plane-number offline all-chassis command to make the spare plane offline on the SFC and each LCC. Replace plane-number with the number of the spare plane. This command will make the four TXP-F2S SIBs and two TXP-F13 SIBs corresponding to the spare plane offline in the SFC, and the TXP-T1600 SIB corresponding to the spare plane offline in each LCC.
  2. Issue the show chassis fabric plane command to verify that the requested switch fabric plane is offline, indicating that the SIBs in each chassis are powered down.
  3. Remove the fiber-optic array cables connected to the offline SIBs in the SFC and each LCC. See Removing Fiber-Optic Array Cables During an Operational Upgrade to a TX Matrix Plus Routing Matrix with 3D SIBs for more information.
  4. Replace the offline SIBs in the spare switching plane in the SFC and each LCC. You must remove the offline TXP-F2S, TXP-F13, and TXP-T1600 SIBs, and replace them with TXP-F2S-3D, TXP-F13-3D, and TXP-LCC-3D SIBs. See Replacing Offline SIBs During an Operational Upgrade to a TX Matrix Plus Routing Matrix with 3D SIBs for more information.
  5. Connect the TXP-F13-3D and TXP-LCC-3D SIBs in the offline switching plane by using the AOCs or CXP transceivers and cables. See Connecting Offline SIBs While Performing Operational Upgrades with 3D SIBs.
  6. Bring each of the SIBs in the offline switching plane online by using one of the following methods:
    • Issue the request chassis fabric plane plane-number online all-chassis command to bring the offline switching plane online. Replace plane-number with the number of the offline switch fabric plane. This will bring each of the offline SIBS in the SFC and each LCC online at one time.

    • Issue the request chassis sib f13 slot slot-number online and request chassis sib f2s sib-slot/sib-f2s-slot-number online commands to bring each offline SIB in the SFC online, and the request chassis sib all-lcc slot slot-number online command to bring each offline SIB in each LCC online.

    • Press the ONLINE/OFFLINE button on each SIB until the OK LED lights green.

  7. Issue the show chassis sibs command to verify that the new SIBs in the SFC and LCCs are online and the state of each SIB is reported as Spare. If the state of any SIB is not reported as Spare, issue the show chassis alarms command to determine if there are any hardware errors.Caution

    If any hardware errors are reported, replace the SIB by using the procedures described in Replacing Offline SIBs During an Operational Upgrade to a TX Matrix Plus Routing Matrix with 3D SIBs. Do not proceed to the next step until the issues are resolved.

  8. Issue the show chassis fabric optics command to verify that the cables have been correctly connected to the new SIBs in the SFC and LCCs. The correct cable state is CABLE_CONNECTED. The following example shows the expected cable state for SIB 0 in an SFC with four connected T1600 LCCs:
    user@host> show chassis fabric optics


    Caution

    If the expected cable state is not displayed for any ports, review the procedures described in Connecting Offline SIBs While Performing Operational Upgrades with 3D SIBs, and review the port-to-port mapping described in Switching Plane Connections Between TXP-F13-3D SIBs and TXP-LCC-3D SIBs to try to resolve any problems. Do not proceed to the next step until the issues are resolved.

  9. Issue the show chassis fabric plane command to verify that the switch fabric plane is operating as the spare, or standby, switch fabric plane. The other four switch fabric planes should be online, indicating that they are operational. Caution

    If one or more switch fabric planes are offline, or if other errors are indicated, use the procedures described in Troubleshooting the TX Matrix Plus TXP-F13 and TXP-F2 SIBs to try to resolve any problems. Do not proceed to the next step until the issues are resolved.

  10. Make the next active switch fabric plane offline by using the request chassis fabric plane plane-number offline all-chassis command. Replace plane-number with the number of the next active switch fabric plane. This command will make the four TXP-F2S SIBs and two TXP-F13 SIBs corresponding to the next active plane offline in the SFC, and the TXP-T1600 SIB corresponding to the next active plane offline in each LCC.

    After the next active plane is offline, the spare switch fabric plane with the installed TXP-F2S-3D, TXP-F13-3D, and TXP-LCC-3D SIBs will come online.

    Caution

    During the upgrade and connection of the switching planes, the routing matrix might experience some packet loss, depending on the operational environment. For more information, contact your customer support representative.

    Note

    After you have upgraded the final switch fabric plane, this step will make the first switch fabric plane you upgraded offline. This ensures that each switch fabric plane functioned as an active plane. The offline switch fabric plane is brought back online later in this procedure (see Completing the Upgrade and Restarting the TX Matrix Plus Routing Matrix).

  11. Issue the show chassis fabric stats f13 rates summary command to verify that traffic is flowing through all four switch fabric planes.Caution

    If traffic is not flowing through the switch fabric plane with the installed TXP-F2S-3D, TXP-F13-3D, and TXP-LCC-3D SIBs bring the switch fabric plane offline using the instructions in Step 1 and back online using the instructions in Step 6 to try to resolve any problems. Do not proceed to the next step until the issues are resolved.

  12. Repeat Steps 2 through 11 for each switch fabric plane. Once you have completed upgrading each switch fabric plane proceed to Completing the Upgrade and Restarting the TX Matrix Plus Routing Matrix.Note

    At the end of this process, all SIBs in all switch fabric planes are upgraded, and traffic has flowed through each switch fabric plane. Four switch fabric planes are online and actively passing traffic. One switch fabric plane is offline. This ensures that each switch fabric plane functioned as an active plane. The offline switch fabric plane is brought back online in the next procedure (see Completing the Upgrade and Restarting the TX Matrix Plus Routing Matrix).

Completing the Upgrade and Restarting the TX Matrix Plus Routing Matrix

To complete the operational upgrade and restart the TX Matrix Plus routing matrix:

  1. Bring each of the SIBs in the last offline switching plane online by using one of the following methods:
    • Issue the request chassis fabric plane plane-number online all-chassis command to bring the offline switching plane online. Replace plane-number with the number of the offline switch fabric plane. This will bring each of the offline SIBS in the SFC and each LCC online at one time.

    • Issue the request chassis sib f13 slot slot-number online and request chassis sib f2s sib-slot/sib-f2s-slot-number online commands to bring each offline SIB in the SFC online, and the request chassis sib all-lcc slot slot-number online command to bring each offline SIB in each LCC online.

    • Press the ONLINE/OFFLINE button on each SIB until the OK LED lights green.

  2. Set the configuration switches on the craft interface of the SFC:
    • Set the CONFIG SIZEto 03.

    • Set the SFC CHASSIS NUMBERto 00.

    See Setting the Configuration Size and Switch-Fabric Chassis Number for more information.

  3. On the SFC, remove the fabric upgrade-mode 3d-fabric statement from the configuration at the [edit chassis] hierarchy level, and commit the configuration.
    user@host# delete fabric upgrade-mode 3d-fabric
    user@host# top
    user@host# commit


  4. Restart the TX Matrix Plus routing matrix by using the request system reboot CLI command.
  5. After the system has restarted, issue the show chassis sibs, show chassis fpcs, and show chassis fabric stats f13 rates summary CLI commands to verify that the TX Matrix Plus routing matrix is functioning properly and has been properly upgraded.
