Description

This article introduces the procedure used to upgrade a Lenovo CE switch running Campus NOS using the Utility Menu. This method should be used if the normal Web GUI or CLI methods are not working, or if corrupted files need to be replaced.

Requirements

• Console access to the switch.
• Management port needs network access to a TFTP server, or the console cable can be used if using XMODEM, YMODEM, or ZMODEM.

Procedure

1. While the switch is powered off, connect to the switch using the console option on your terminal emulator.
2. Power the switch on and carefully watch the displayed text. You will only have three seconds to make a selection from the menu.
3. Select 2 when given the option to choose from the Lenovo Campus NOS Startup – Main Menu.
