TX Matrix Troubleshooting Resources

 

To troubleshoot a TX Matrix router, you use the Junos OS command-line interface (CLI), LCD, alarms, devices connected to the alarm relay contacts on the TXP-CIP, and LEDs on both the components and craft interface.

  • LEDs—When the Routing Engine detects an alarm condition, it lights the red or yellow alarm LED on the craft interface as appropriate. In addition, you can also use the component-specific LEDs on the craft interface and on the faceplate of a component to troubleshoot the routing matrix.

  • LCD—When a red or yellow alarm occurs, the cause of the alarm messages is displayed on the craft interface LCD. Use the CLI to display more information about the alarm.

  • Alarm devices connected to the alarm relay contact on the TXP-CIP—When a red or yellow alarm occurs, it trips the corresponding alarm relay contact on the TXP-CIP.

  • CLI—The CLI is the primary tool for controlling and troubleshooting hardware, Junos OS, routing protocols, and network connectivity. CLI commands display information from routing tables, information specific to routing protocols, and information about network connectivity derived from the ping and traceroute utilities.

    For information about using the CLI to troubleshoot the Junos OS, see the appropriate Junos OS feature guide.

    Note

    For troubleshooting only, you can access a T640 router by connecting a T640-CIP to an external management device. However, you manage the routing matrix through external management devices connected to the TX-CIPs on the TX Matrix router.

  • JTAC—If you need assistance during troubleshooting, you can contact the Juniper Networks Technical Assistance Center (JTAC) by using the Web or by telephone. If you encounter software problems, or problems with hardware components not discussed here, contact JTAC.
