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 TXÂ 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. |
You must proceed through the procedures in the following order. To upgrade and connect an operational T1600 router:
- Prepare to upgrade and integrate the operational
T1600 router.
See Overview of Preparing to Upgrade and Integrate an Operational T1600 Router.
- Unpack the T1600 router components and verify the parts received.
- Gather the tools required for the upgrades and
integration.
See Tools and Parts Required for Upgrading and Integrating an Operational T1600 Router.
- Configure graceful switchover on the T1600 router.
See Upgrading the T1600 Host Subsystems in an Operational T1600 Router.
- 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.
- Upgrade the host subsystems.
See Upgrading the T1600 Host Subsystems in an Operational T1600 Router.
- Upgrade the Junos OS on the new Routing Engines
to Release 10.1 or later.
See Upgrading the JUNOS Software on an Operational T1600 Router and TX Matrix Plus Router.
- Upgrade the power supplies, if required.
See Upgrading the T1600 Power Supplies in an Operational T1600 Router.
- Upgrade the rear fan tray, if required.
See Upgrading the Rear Fan Tray in an Operational T1600 Router.
- Create a T1600 configuration file for integration
into the routing matrix.
See Creating a Configuration File for the Integration of an Operational T1600 Router.
- Prepare to upgrade the SIBs.
See Upgrading and Connecting the Switching Planes in an Operational T1600 Router.
- 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.
- Connect and integrate each remaining switching
plane one at a time.
See Upgrading and Connecting the Switching Planes in an Operational T1600 Router.
- Connect the control planes between an operational
T1600 router and TX Matrix Plus router.
See Connecting the Control Planes in an Operational T1600 Router.
- Set the M/S switch on each LCC-CB faceplate
to M.
See Setting the M/S Configuration Switches on the T1600 LCC-CBs.
- Transfer the T1600 configuration file to the routing matrix.
- 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 .
