You may be asked for a serial number on one of the Nile Service Block (NSB) network elements. This could occur if you need to locate an unplugged device like a Sensor or identify if power has been cut to a Switch. Below is the method to find the serial numbers for each of the NSB network elements.

Youtube Video demos of finding the Serial Number. Pictures and descriptions below videos.
