2. Module on-board identification
      Connect the SFP-25G-SL module to CISCO N9K-C93180YC-EX switch, access the patch cord, the module can be normally LINK, the port indicator lights up; module information can be normally recognized by the switch, such as the module type, vendor name, model number, serial number, rate, transmission distance, etc.; you can read the DOM data, and the DOM data are all within the threshold range, no alarm phenomenon. alarm phenomenon.
