Chassis Alarm Messages on a QFX3600 or QFX3600-I Device

 

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

The chassis alarm message count is displayed on the LCD panel on the front of the device. To view the chassis alarm message text remotely, use the show chassis lcd CLI command.

Chassis alarms on QFX3600 and QFX3600-I 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 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 QFX3600 and QFX3600-I devices.

CLI Message

Recommended Action

Fans

Major (red)

Fan Failure

Replace the fan 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 may be 1, 2, or 3.

Fan fan-number Not Spinning

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

Minor (yellow)

Fan/Blower Absent

The fan is missing. Install a fan.

Power supplies

Major (red)

PEM pem-number Airflow not matching Chassis Airflow

The power supply airflow direction is the opposite of the chassis airflow direction. 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

For information only. Check the power cord connection and reconnect it if necessary.

PEM pem-number is not supported

Indicates a power supply problem, or the power supply is not supported on the device. Report the problem to customer support.

PEM pem-number Not OK

Indicates a problem with the incoming AC or outgoing DC power. Replace the power supply.

Minor (yellow)

PEM pem-number Absent

For information only. Indicates the device was powered on with two power supplies installed, but now one is missing. The device can continue to operate with a single power supply. If you wish to remove this alarm message, reboot the device with one power supply.

PEM pem-number Power Supply Type Mismatch

For information only. Indicates that an AC power supply and DC power supply have been installed in the same chassis. If you wish to remove this alarm message, reboot the device with two AC power supplies or two DC power supplies.

PEM pem-number Removed

For information only. Indicates the device was powered on with two power supplies installed, but one has been removed. The device can continue to operate with a single power supply. If you wish to remove this alarm message, reboot the device with one 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 may range 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) are not affecting the temperature sensor. If the condition persists, the device may 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) are not affecting the temperature sensor.
