Troubleshooting the PTX10003

 

PTX10003 Troubleshooting Resources Overview

To troubleshoot a PTX10003, 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. In addition, you can also use component LEDs and network port LEDs to troubleshoot the PTX10003. For more information, see the following topics:

  • 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 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.

PTX10003 Alarm Messages Overview

When the Routing Engine 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 system alarms CLI command:

user@host> show system alarms

System alarms indicate a failure on the device or one of its components. System alarms are preset and cannot be modified.

System alarms on PTX10003 routers 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 system alarm messages on the PTX10003.

Component

Alarm Type

CLI Message

Recommended Action

Fans

Major (red)

Fan Failure

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

Fan I2C Failure

Check the system log for one of the following messages and report the error message to customer support:

  • CM ENV Monitor: Get fan speed failed.

  • fan-number is NOT spinning @ correct speed, where fan-number can be 1, 2, or 3.

Fan fan-number Not Spinning

Remove and check the fan module for obstructions, and then reinsert the fan module. If the problem persists, replace the fan module.

Minor (yellow)

Fan/Blower Absent

Check the system log for the message fan-number Absent, where fan-number can be 1, 2, or 3.

Install the fan module.

Power supplies

Major (red)

PSMx Fan Failure

Replace PSM and RMA

PSMx Input Failure

Check input power feeds

Minor (yellow)

Zone 0 N+2 Power redundancy missing

Install a redundant PSM and check the input power feeds

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. Ensure that environmental factors (such as hot air blowing around the equipment) do not affect the temperature sensor. If the condition persists, the device might shut down.

Minor (yellow)

sensor-location Temp Sensor Too Warm

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

Routing Engine

Minor (yellow)

RE RE number /var partition usage is high

Clean up the system file storage space on the device.

Major (red)

RE RE number /var partition is full

Clean up the system file storage space on the device.

Minor (yellow)

Rescue configuration is not set

Use the request system configuration rescue save command to set the rescue configuration.

Feature usage requires a license



or



License for feature expired

Install the required license for the feature specified in the alarm.

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 the problem cannot be resolved, 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 and Canada)or 1-408-745-9500 (from outside the United States).
