Description

This upgrade page introduces the different procedures that can be used to upgrade Lenovo switching devices running ENOS(Enterprise Network Operating System) or CNOS(Campus Network Operating System). These procedures all require a network connection from the switch to a device holding the software, and they may also need console access. In most cases, the transfer methods include FTP, TFTP, SFTP, and SCP.
