When you upgrade from an existing release on your switch to a later or newer release for the first time, and there is a new ROMMON version in the new release, the system automatically upgrades the ROMMON in the primary SPI flash device, based on the hardware version of the switch. These modules typically consist of a transmitter, which converts electrical signals into a light signal, and a receiver, which converts the received signal back. Presently, laser diodes (LD) are commonly used as the light source in most optical modules. However, LED remains a viable.
