This chapter describes the procedure for upgrading the switch software
image. This chapter also discusses how to save and load a primary and
secondary image and configuration file on the switch.
The image file contains the executable code that runs on the switch. It
comes preinstalled from the factory. As new versions of the image are
released, you should upgrade the software running on your system.
The image is upgraded by using a download procedure from either a
Trivial File Transfer Protocol (TFTP) server on the network or from a PC
connected to the serial port using the XMODEM protocol. Downloading a
new image involves the following steps:
Load the new image onto a TFTP server on your network (if you will be
using TFTP).
Load the new image onto a PC (if you will be using XMODEM).
Download the new image to the switch using the command
download image [xmodem | <ipaddress>] <filename>] {primary
| secondary}
where the following is true:
— Indicates that you will be using XMODEM over the serial
xmodem
port.
— Is the IP address of the TFTP server.
ipaddress
— Is the filename of the new image.

— Indicates the primary image.
