Message:<Function name> <Error string>.
Message Type: FFDC | LOG
Severity: CRITICAL
Probable Cause: Indicates that nonrecoverable peripheral component interconnect (PCI) errors have been detected.
Recommended Action: The system will be faulted and may reload automatically.
If the system does not reload, execute the reload command.
Execute the copy support command and contact your switch service provider.
Message: MM<Identifies which MM (1 or 2) is doing the reset> resetting other MM (double reset may occur).
Message Type: LOG
Severity: INFO
Probable Cause: Indicates that the other management module is being reset. This message is typically generated by a management module that is in the process of becoming the active management module. Note that in certain circumstances a management module may experience a double reset and reload twice. A management module can recover automatically even if it has reloaded twice.
Recommended Action: No action is required.
Message: MM<Identifies which MM (1 or 2) is generating the message>: <Warning message> hk_fence 0x<MM Housekeeping Fence register. Contents are platform-specific> mm_ha 0x<MM HA register. Contents are platform-specific> mm_status 0x<MM Status register. Contents are platform-specific>.
Message Type: LOG
Severity: WARNING
Probable Cause: Indicates that one of the management modules cannot access the inter-integrated circuit (I2C) subsystem because of an error condition or being isolated from the I2C bus.
Recommended Action: Reload the management module if it does not reload automatically. Reseat the management module if reloading does not solve the problem. If the problem persists, replace the management module.
Message: Turning off Fan <Fan Number> because of airflow direction mismatch.
Message Type: LOG | FFDC
Severity: CRITICAL
Probable Cause:Indicates that the specified fan field-replaceable unit (FRU) has been turned off because it is incompatible with the system airflow direction policy.
Recommended Action: Replace the fan FRU. Refer to the Hardware Reference Manual of your switch for instructions to replace the fan FRU.
Message: Unable to read EEPROM for Global airflow direction. Setting to default Port side intake.
Message Type: LOG | FFDC
Severity: CRITICAL
Probable Cause: Indicates a failure to read the electrically erasable programmable read-only memory (EEPROM) to determine the airflow direction of the fans. Therefore, setting the airflow direction to be from the port side of the system.
Recommended Action: Execute the copy support command and contact your switch service provider.
Message: Unable to read EEPROM for Global airflow direction. Shutting off Fans now.
Message Type: LOG
Severity: CRITICAL
Probable Cause: Indicates a failure to read the electrically erasable programmable read-only memory (EEPROM) to determine the airflow direction of the fans. The fans will be shut down.
Recommended Action:Execute the copy support command and contact your switch service provider.
Message: Turning off Fan <Fan Number> because of airflow direction <Global airflow direction>.
Message Type: LOG
Severity: ERROR
Probable Cause: Indicates that the specified fan is turned off because of an incorrect airflow direction.
Recommended Action:Replace the fan field-replaceable units (FRUs) in such a manner that the air flows in the same direction, that is, towards the port side or away from the port side of the system. Refer to the Hardware Reference Manual of your switch for instructions to replace the fan FRU.
Message: Unable to read EEPROM for Global airflow direction.
Message Type: LOG
Severity: ERROR
Probable Cause: Indicates a failure to read the electrically erasable programmable read-only memory (EEPROM) and therefore unable to determine the global airflow direction of the fans.
Recommended Action: Execute the copy support command and contact your switch service provider.
Message: Unable to read EEPROM Valid Signature for Global airflow direction.
Message Type: LOG
Severity: ERROR
Probable Cause: Indicates that the content read from electrically erasable programmable read-only memory (EEPROM) is invalid and therefore unable to determine the global airflow direction of the fans.
Recommended Action: Execute the copy support command and contact your switch service provider.
Message: Switch has older FPGA revision <Current FPGA revision>. FPGA revision <Available FPGA revision> is available.
Message Type: LOG
Severity: WARNING
Probable Cause: Indicates that the firmware download command has downloaded a latest FPGA that is not activated yet.
This log is specific to platform EN4023 and Extreme VDX 2746. This log will not appear in other platforms.
Recommended Action: To activate the latest FPGA, power on reset the switch by doing one of the two steps: physically reseat the switch from the chassis or execute the command 'service -vr' from CMM CLI.
Message: Switch has older FPGA revision <FPGA version already installed in HW>. The latest FPGA revision <FPGA version which NOS-Fusion carries> is available.
Message Type: LOG
Severity: WARNING
Probable Cause: Indicates that the firmware download command has downloaded a latest FPGA that is not activated yet.
This log is specific to platform Fusion. This log will not appear in other platforms.
Recommended Action: It is highly recommended that FPGA be upgraded to the latest version.
To activate the latest FPGA, power on reset the switch: physically reseat the switch from the chassis
Message: Linecard:<Latch Screws Status> Version:<Latch Screws Status>; Latch Screw Left:<Latch Screws Status> Right:<Latch Screws Status>
Message Type: LOG
Severity: INFO
Probable Cause:Indicates that the 2 latch screws are installed or not
Recommended Action:No action is required.
Message: Linecard:<Latch Optical Switch Feature Enabled/Disable> Latch Optical Switch Feature is <Latch Optical Switch Feature Enabled/Disable>.
Message Type: LOG
Severity: INFO
Probable Cause:Indicates that the latch optical switch feature is disabled or enabled
Recommended Action:No action is required.
