Abstract: A power backup method for use in a communication network monitoring device and a communication network monitoring device are provided. The method includes detecting an external power failure to a communication network monitoring device; switching to a backup power source internal to the communication network monitoring device upon detecting the external power failure: and while powered by the backup power source: generating an issue report recording the detected external power failure; communicating the issue report; shutting down operation of the communication network monitoring device after communicating the issue report.
