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:
| ||
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:
| ||
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. |
