Cisco ONS 15501 Alarms
This appendix describes the alarms defined for the Cisco ONS 15540:
•Ambient Temperature
[Temperature out of range]
Explanation The temperature measured by the thermal sensor shows a value outside the operational limits.
Recommended Action Change environment so that the chassis cools down.
•Electrical Power
[Power Supply voltage level out of range]
Explanation The measured power supply levels are not within range.
Recommended Action Ensure proper voltage levels for both the electrical inputs.
•Input Signal Power
[Input Signal level out of range]
Explanation The measured input signal power is not within range.
Recommended Action The device might be operating outside the configured input optical limits. Change the mean and trigger values appropriately, or check the equipment and link providing optical input to the unit.
•Output Signal Power
[Output Signal level out of range]
Explanation The measured output signal power is not within range.
Recommended Action The device may be operating outside of specified limits or the mean and trigger are not properly defined. Change the mean and trigger values appropriately, vary the optical input, or change the configured gain so that the output signal power is in the operational range.
•Controller communication failure
[Communication with embedded controller failed]
Explanation The communication with the embedded controller has failed.
Recommended Action This denotes internal monitoring failure. The unit needs servicing if this alarm appears frequently.
•Software Upgrade Initiated
[Software download started]
Explanation A TFTP or FTP request has been launched.
Recommended Action None.
•Software Upgrade Failed
[Software download failed]
Explanation A TFTP or FTP request that was launched has failed.
Recommended Action Fix the reported problem (network issues, bad user ID or password, remote server not configured or incorrect, filename or file path incorrect) and relaunch the software download with correct parameters.
•Software Upgrade Completed
[Software download completed]
Explanation A TFTP or FTP request that was launched has completed.
Recommended Action None.
•Software Reboot Initiated
[Software Reboot issued]
Explanation Reboot has been requested on the unit
Recommended Action None
•Software Rolled Back
[Active and planned Software images are different]
Explanation The unit has booted from a bank that is not the programmed bank. This is possibly because the image from programmed bank was bad or because the boot loader was explicitly asked to boot from another bank (using the console during boot-up) or unit was frequently power-cycled.
Recommended Action If the image is bad, reprogram a good image on corrupted bank.
•Configuration Changed
[Configurable value modified]
Explanation A writeable attribute has been modified through one of the management interfaces exposed by the system (for example, CLI or SNMP).
Recommended Action None
•Unacceptable Gain
[Measure signal gain is out of acceptable range]
Explanation The equipment is unable to achieve the planned level for gain.
Recommended Action Ensure that the optical input and environmental factors are within operational range. If the alarm is still present, the unit might need servicing.
•Laser Pump Bad
[One or more of the laser pump(s) bad]
Explanation The measured parameters for the laser show that a laser pump has gone bad.
Recommended Action Ensure that the optical input and environmental factors are within operational range. If the alarm is still present, the unit needs servicing.
•EEPROM bad
[EEPROM access showed up errors]
Explanation The writes and reads from EEPROM have problems.
Recommended Action If this problem recurs, it denotes a fault with the monitoring interface and may require servicing.
