What to do if my Cisco ASR-920-12SZ-IM shows a red light due to fan failures and critical error?

If your Cisco Network Router is showing a red light due to single or multiple fan failures and a critical error, this indicates a problem with the device's cooling system. Ensure that the fans are free from obstructions and are functioning correctly. If the issue persists, it indicates a serious hardware problem.
