PTX5000 Troubleshooting Resources Overview
To troubleshoot a PTX5000, you use the Junos OS command-line interface (CLI), LCD, alarms, devices
connected to the alarm relay contacts, 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 PTX5000.
• 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.
