Troubleshooting QFX10002 Components
QFX10002 Troubleshooting Resources Overview
To troubleshoot problems on a QFX10002, use the Juniper Junos OS command-line interface (CLI), and the LEDs on the field -replaceable unit (FRU) and the management panel.
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 Junos OS software documentation.
LEDs—When the switch detects an alarm condition, it lights the red or yellow status alarm LED on the management panel. In addition, the individual fans and power supplies also have status indicators.
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.

QFX Series Alarm Messages Overview
When a QFX Series switch detects an alarm condition, it lights
the red or yellow alarm LED on the management panel as appropriate.
To view a more detailed description of the alarm cause, issue the show chassis alarms
CLI command:

For Junos OS Evolved systems, show system alarms
CLI command indicates major and minor alarms on the system. In this
example from a Junos OS Evolved system, a fan tray error is shown
in slot 4.

Chassis Alarm Messages on QFX10002 Switches
Chassis alarms indicate a failure on the device or one of its components. Chassis alarms are preset and cannot be modified.
Chassis alarms on QFX10002 switches have two severity levels:
Major (red)—Indicates a critical situation on the device that has resulted from one of the conditions described in Table 1. A red alarm condition requires immediate action.
Minor (yellow or amber)—Indicates a noncritical condition on the device that, if left unchecked, might cause an interruption in service or degradation in performance. A yellow alarm condition requires monitoring or maintenance.
Table 1 describes the chassis alarm messages on QFX10002 devices.
