Description

This article introduces the procedure used to upgrade a Lenovo CE switch running Campus NOS using the CLI.

Procedure

1. Establish a connection to the switch.
2. Using the copy command and a selected transfer protocol, copy the IMGS file into the backup image.
   Note: For the examples in this article, FTP will be used to transfer the file from FTP server IP 10.10.10.1. The original filename has been renamed to simplify the command (CE0128PB.imgs). The original filename looks like this: CE0128XB_CE0152XB-CampusNOS-r8v4m3b13.imgs.
