Overview of Preparing to Upgrade and Integrate 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 Plus 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.

To prepare to upgrade and integrate an operational T1600 router:

1. Verify that you have the required rear fan tray. An upgraded rear fan tray (part number 760-024613) is required to cool the chassis. Part number 760-009870 is not supported for a T1600 router in a routing matrix.
2. Verify that you have the required power supplies. An upgraded three-input 240-A power supply (part number 740-026384) or a four-input 240-A power supply is required. The three-input 240-A power supply (part number 740-017906) is not supported for a T1600 router in a routing matrix.
3. Order the hardware. The hardware upgrade kit includes two LCC-CBs and five TXP-T1600 SIBs. The Routing Engines must be ordered separately. The rear fan tray and power supplies, if needed, can also be ordered separately.

   See the T1600 Core Router Hardware Guide.

4. Prepare the installation site for the T1600 router.

   See Overview of Preparing the Site for a TX Matrix Plus Router and the T1600 Core Router Hardware Guide.

5. Review all safety guidelines and warnings for both the TX Matrix Plus router and T1600 router.

   Warning: To avoid harm to yourself or the TX Matrix Plus router as you install and maintain it, you must follow the 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 for M Series, MX Series, and T Series Routers and General Safety Warnings for M Series, MX Series, and T Series Routers.

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

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

Note: Additional T1600 routers you integrate must be offline.
