Downloading a New Image
The image file contains the executable code that runs on the switch and is preinstalled at 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:
• Loading the new image onto a TFTP server on your network (if you will be using TFTP).
• Loading the new image onto a PC (if you will be using XMODEM).
• Selecting the partition to use when downloading an image. For more information, see “Selecting a
Primary or a Secondary Image” on page 312.
• Downloading the new image to the switch using the following command:
download image [[<hostname> | <ipaddress>] <filename> {{vr} <vrname>} | memorycard
<filename>] {<partition>}
Before the download begins, the system asks if you want to install the image immediately after the
download is finished. If you install the image immediately after download, you must reboot the
switch. Enter
y to install the image immediately after download. Enter n to install the image at a
later time.
