QFX5200 Troubleshooting Resources Overview
To troubleshoot a QFX5200, you use the Junos OS CLI, alarms, and LEDs on the network ports,
management panel, and components.
• LEDs—When the Routing Engine detects an alarm condition, it lights the red or yellow alarm LED on
the management panel as appropriate. In addition, you can also use component LEDs and network
port LEDs to troubleshoot the QFX5200. For more information, see the following topics:
• "QFX5200 Chassis Status LEDs" on page 24
• "QFX5200 Management Panel Overview" on page 18
• "QFX5200-32C and QFX5200-32C-L Port Panel" on page 9
• "QFX5200-48Y Port Panel" on page 13
• "QFX5200-32C and QFX5200-32C-L Fan Module LED" on page 37
• "QFX5200 AC Power Supply LEDs" on page 45
• "QFX5200 DC Power Supply LEDs" on page 52
• 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 Junos OS, see
the appropriate Junos OS configuration guide.
• 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.
