Troubleshoot the PTX10002-36QDD

Troubleshooting Overview

To troubleshoot a PTX10002-36QDD, you use the Junos OS Evolved 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. You can also use component LEDs and network port LEDs to diagnose issues with the router.

  • CLI—The CLI is the primary tool for controlling and troubleshooting hardware, Junos OS Evolved, 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 Evolved, see the appropriate Junos OS Evolved user guide.

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.

System Alarm Messages

When there is an alarm condition, the alarm LED on the management panel is lit. The alarms indicate a failure on the device or on one of its components. The alarms are preset; you cannot modify them.

The alarms on PTX10002-36QDD routers have two severity levels:

  • Major (red)—Indicates a critical situation on the router 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 router that, if left unchecked, might cause an interruption in service or degradation in performance. A yellow alarm condition requires monitoring or maintenance.

Component

Alarm Type

CLI Message

Recommended Action

Fan module

Major (red)

Fan Tray fan-tray-number Absent

Replace the fan module.

Major (red)

Fan Tray fan-tray-number Fail

Replace the fan module and report the failure to customer support.

Management Ethernet interface

Major (red)

Management Ethernet 1 Link Down

Check whether a cable is connected to the management Ethernet interface, or whether the cable is defective. Replace the cable, if required.

If you are unable to resolve the problem, open a support case by using the Case Manager link at https://www.juniper.net/support/ or call 1-888-314-5822 (toll free, US or 1-408-745-9500 (from outside the United States).

Power supply unit (PSU)

Major (red)

PSM psm-number I2C Fail

Report the failure to customer support.

PSM psm-number Not OK

The input or output voltage is not in range. Replace the PSU.

PSM psm-number Health Check Fail

The PSU health check has failed. Replace the PSU.

PSM psm-number Input1 Failed

The input has failed. Replace the PSU.

PSM psm-number High Temp

The PSU temperature is high. Replace the PSU.

Minor (yellow)

PSM psm-number Fan1 Fail

Fan 1 in the PSU has failed. Replace the PSU.

PSM psm-number Fan2 Fail

Fan 2 in the PSU has failed. Replace the PSU.

Routing engine

Minor (yellow)

RE RE number /var partition usage is high

Clean up the system file storage space on the router to reduce active disk usage. For more information, see request system storage cleanup.

Temperature sensors

Major (red)

sensor-location Temp Sensor Fail

Check the system log for the following message and report it to customer support:

Temp sensor sensor-number failed, where sensor-number ranges from 1 through 10.

sensor-location Temp Sensor Too Hot

Check environmental conditions and alarms on other devices installed near the router. Ensure that environmental factors (such as hot air blowing around the equipment) do not affect the temperature sensor. If the condition persists, the router might shut down.

Minor (yellow)

sensor-location Temp Sensor Too Warm

For information only. Check environmental conditions and alarms on other devices installed near the router. Ensure that environmental factors (such as hot air blowing around the equipment) do not affect the temperature sensor.
