Switch Types Codes with the corresponding Switch model | Firmware upgrade

Hi Dear Community 

I want to know how to determine the Brocade Switch Model and Dell-EMC Model on the output that I got from the "switchshow" (SwitchType=162.6)

I just want to find out something like that

Apart from that I want to perform a firmware upgrade for this switch but I don't know how to get the firmware files. The current firmware version for this device 

Thanks in advance for your help
