Troubleshooting the ACX6360

ACX6360 Troubleshooting Resources Overview

To troubleshoot an ACX6360, 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 ACX6360. For more information, see the following topics:

  • 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.

ACX6360 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 chassis alarms CLI command:

Chassis Alarm Messages on the ACX6360

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

Chassis alarms on ACX6360 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 chassis alarm messages on the ACX6360.

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, 3, 4, or 5.

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, 3, 4, or 5.

Install the fan module.

Power supplies

Major (red)

PEM pem-number Airflow not matching Chassis Airflow

Replace the power supply with a power supply that supports the same airflow direction as the chassis.

PEM pem-number I2C Failure

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

  • I2C Read failed for device number, where number may be from 123 to 125.

  • PS number: Transitioning from online to offline, where power supply (PS) number may be 1 or 2.

PEM pem-number is not powered

Check the power cord connection and reconnect, if necessary.

PEM pem-number is not supported

Replace the power supply with a supported power supply.

PEM pem-number Not OK

Indicates a problem with the incoming AC power or outgoing DC power. Report the error to customer support.

Minor (yellow)

PEM pem-number Absent

A power supply is not installed. Install a supported power supply in the appropriate slot.

PEM pem-number Power Supply Type Mismatch

Check if there is a mix of AC and DC power supplies in the same chassis. Reboot the device with only AC or only DC power supplies.

PEM pem-number Removed

Replace the removed power supply.

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

Major (red)

RE RE number /var partition is full

Clean up the system file storage space on the device. For more information, see request system storage cleanup.

Minor (yellow)

RE RE number /var partition usage is high

Clean up the system file storage space on the device. For more information, see request system storage cleanup.

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.
