QFX10000 Troubleshooting Resources Overview
To troubleshoot a QFX10000 modular chassis, 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 QFX10000. For more information, see the following topics:
•
Status Panel
•
QFX10000 Routing and Control Board LEDs
•
QFX10000 Line Card LEDs
•
QFX10000 Fan Tray LEDs and Fan Tray Controller LEDs
•
QFX10000 AC Power Supply LEDs
and
QFX10000-PWR-DC Power Supply LEDs
• 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.
