Chassis Alarm Messages

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

Chassis alarms on QFX5100, QFX5110, QFX5210, and QFX5120 devices 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)—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 QFX5100, QFX5110, QFX5200, QFX5210, and QFX5120 devices.

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 error messages and report the 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 error message fan-number Absent, where fan-number can be can be 1, 2, 3, 4, or 5.

Install fan modules in the slots where they are absent.

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 supported by the chassis.

PEM pem-number I2C Failure

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

  • I2C Read failed for device number, where number where number ranges from 123 through 125.

  • PS number: Transitioning from online to offline, where power supply number is 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

Reboot the switch after removing one of the power supply. The switch can continue to operate with a single power supply.

OR

Replace the removed power supply and reboot the switch.

PEM pem-number Power Supply Type Mismatch

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

PEM pem-number Removed

Replace the removed power supply or reboot the switch. The switch can continue to operate with a single power supply.

Temperature sensors

Major (red)

sensor-location Temp Sensor Fail

Check the system log for the following error message and report the message 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

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 switch. For more information, see Cleaning Up the System File Storage Space.

Major (red)

RE RE number /var partition is full

Clean up the system file storage space on the switch. For more information, see Cleaning Up the System File Storage Space.

Minor (yellow)

Rescue configuration is not set

Use the request system configuration rescue save command to set the rescue configuration. For more information, see Setting or Deleting the Rescue Configuration.

Feature usage requires a license

or

License for feature expired

Install the required license for the feature specified in the alarm. For more information, see Software Features That Require Licenses on the QFX Series.

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.

On models that have both em0 and em1 management interfaces available, you must connect both interfaces. If both interfaces are not connected, the alarm is raised. However, the alarm has no service impact.
