Overview of Upgrading and Integrating an Operational T1600 Router

Note: Only the first T1600 router you integrate with the TX Matrix Plus router can be operational. During the integration of an operational T1600 router with the TX Matrix router, the T1600 router continues to pass traffic until it is rebooted. The traffic interruption during the reboot is comparable to the interruption that occurs during a Junos OS major upgrade.

1. Prepare to upgrade and integrate the operational T1600 router.

   See Overview of Preparing to Upgrade and Integrate an Operational T1600 Router.

2. Unpack the T1600 router components and verify the parts received.
3. Gather the tools required for the upgrades and integration.

   See Tools and Parts Required for Upgrading and Integrating an Operational T1600 Router.

4. Configure graceful switchover on the T1600 router.

   See Upgrading the T1600 Host Subsystems in an Operational T1600 Router.

5. Upgrade the Junos OS on the existing Routing Engines to Release 10.1 or later.

   See Upgrading the T1600 Host Subsystems in an Operational T1600 Router.

6. Upgrade the host subsystems.

   See Upgrading the T1600 Host Subsystems in an Operational T1600 Router.

7. Upgrade the Junos OS on the new Routing Engines to Release 10.1 or later.

10. Create a T1600 configuration file for integration into the routing matrix.

    See Creating a Configuration File for the Integration of an Operational T1600 Router.

11. Prepare to upgrade the SIBs.

    See Upgrading and Connecting the Switching Planes in an Operational T1600 Router.

12. Connect and integrate one switching plane.

    See Upgrading and Connecting the Switching Planes in an Operational T1600 Router.

    Note: During the upgrade and connection of the switching planes, the T1600 router might experience some packet loss, depending on the operational environment. For more information, contact your customer support representative.

13. Connect and integrate each remaining switching plane one at a time.

    See Upgrading and Connecting the Switching Planes in an Operational T1600 Router.

14. Connect the control planes between an operational T1600 router and TX Matrix Plus router.

    See Connecting the Control Planes in an Operational T1600 Router.

15. Set the M/S switch on each LCC-CB faceplate to M.

    See Setting the M/S Configuration Switches on the T1600 LCC-CBs.

16. Transfer the T1600 configuration file to the routing matrix.

    See Transferring the T1600 Router Configuration to the TX Matrix Plus Router in an Operational T1600 Router.

17. Transfer control of the T1600 router to the TX Matrix Plus router.

    See Transferring Control of the T1600 Router to the TX Matrix Plus Router .

Note: Additional T1600 routers you integrate must be offline. Follow the procedures described in Overview of Upgrading an Offline T1600 Router Before Integrating It into a Routing Matrix and Overview of Integrating an Offline T1600 Router into a Routing Matrix.
