Overview of Integrating an Operational T640 Router with the TX Matrix Router

Note: Only the first T640 router that you integrate with the TX Matrix router can be operational. Additional T640 routers you integrate must be offline.

During the integration of an operational T640 router with the TX Matrix router, the T640 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.

Note: During the conversion and connection of the switching planes, the T640 router might experience some packet loss, depending on the operational environment. For more information, contact your customer support representative.

To convert and connect a switching plane of an operational T640 router:

1. Verify that the fiber-optic array cables have been routed between the TX Matrix router and the T640 router.

   See Routing the TX Matrix Fiber-Optic Array Cables.

2. Verify that the the fiber-optic array cables have been tested and connected to the TX Matrix router.

   See Connecting the Fiber-Optic Array Cables to the TX Matrix Router and Testing the TX Matrix Fiber-Optic Array Cables.

3. Before you connect a T640 router to the TX Matrix router, you must perform the conversion tasks.

   See Overview of Converting a T640 Router.

   If any problems occur during the conversion procedure, you can convert the T640 router back to its original state.

4. Gather the tools required for the integration.

   See Tools and Parts Required for Integrating an Operational T640 Router with the TX Matrix Router.

5. Convert and connect the control planes between an operational T640 router and TX Matrix router.
