Chassis Alarm Messages on a QFX3008-I Interconnect 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 a QFX3008-I Interconnect device 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 a QFX3008-I Interconnect device.

Table 1: QFX3008-I Chassis Alarm Messages

Component

Alarm Type

CLI Message

Recommended Action

Control Board and Routing Engine

Note: The Routing Engine is located on the Control Board

Major (red)

slot-number CB Not online

Replace the Control Board and report the failure to customer support

Backup RE Active

No action is required if the backup Routing Engine was intentionally made active.

If the master Routing Engine failed, replace it.

Loss of communication with Backup RE

Replace the failed Control Board.

Mixed Master and Backup RE types

Both Routing Engines must be the same model number.

Replace one of the Control Boards.

CB slot-number CPE Connectivity down

Indicates that all links from the control board to the QFabric system control plane network are down.

Check connectivity between the QFX3008-I Interconnect device and the EX4200 switches.

Minor (yellow)

CB slot-number Removed

Indicates the chassis was powered on with both Control Boards installed, but one has been removed. The chassis can continue to operate without the Control Board, but airflow can be affected by the empty slot. Replace the missing Control Board as soon as possible.

Fans

Major (red)

Fan-name Failure

Replace the fan and report the failure to customer support.

Fan-name 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-name is NOT spinning @ correct speed

Minor (yellow)

Fan-name Absent

Indicates the chassis was powered on without all the fan trays installed. The chassis can continue to operate without the fan tray for a limited time, but airflow can be affected by the empty slot. Replace the missing fan tray as soon as possible.

Fan-name No Fan

Indicates the chassis was powered on with all power supplies installed, but one has been removed. The chassis can continue to operate without the power supply, but airflow can be affected by the empty slot. Replace the missing power supply as soon as possible.

Fan-name Overspeed

The fan is spinning faster than necessary. There is no action required. If the problem persists, report the error to customer support.

Front and rear cards

Major (red)

FPC slot-number Hard errors

Replace the specified card and report the failure to customer support.

FPC slot-number Volt Sensor Fail

Replace the specified card and report the failure to customer support.

Power supplies

Major (red)

PEM pem-number Input Failure

Indicates a problem with the incoming AC power. Replace the power supply.

PEM pem-number Not OK

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

PEM pem-number Output Failure

Indicates a problem with the outgoing DC power. Replace the power supply.

PEM pem-number Too Many I2C Failures

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

  • I2C Read failed for device number

  • PS number: Transitioning from online to offline

Too Many Supplies Missing

Too many power supplies have been removed from the chassis. Replace missing power supplies.

Unrecognized

There is a problem with the power supply, replace the power supply and contact Juniper Technical Assistance Center (JTAC).

Minor (yellow)

PEM pem-number Absent

Indicates the chassis was powered on without all the power supplies installed. The chassis can continue to operate without the power supply, but airflow can be affected by the empty slot. Replace the missing power supply as soon as possible.

PEM pem-number Removed

Indicates the chassis was powered on with all power supplies installed, but one has been removed. The chassis can continue to operate without the power supply, but airflow can be affected by the empty slot. Replace the missing power supply as soon as possible.

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 switch 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.
