Downloading a New Image

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:
• 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 228.
• Downloading the new image to the switch using the following command:
download image [<hostname> | <ipaddress>] <filename> {[{vr} <vrid>]}
Where the following is true:
hostname
ipaddress
filename
—Is the name of the virtual router.
vrid
