2. Module On-Board Identification
        Insert the 740-061409 module into a Juniper QFX5200-32C switch. The module establishes a normal link, and the port indicator lights up. The switch can correctly identify module information, including module type, part number, serial number, rate and transmission distance. DOM data can be read normally; all parameters are within the threshold range with no alarms.
