Release Notes for the Cisco IE 2000 Switches, Cisco IOS Release 15.2(1)EY
NEW DOC # PENDING
Upgrading the Switch Software
Deciding Which Files to Use
The upgrade procedures in these release notes describe how to perform the upgrade by using a combined
tar file. This file contains the Cisco IOS image file and the files needed for the embedded Express Setup.
You must use the combined tar file to upgrade the switch through Express Setup. To upgrade the switch
through the CLI, use the tar file and the
archive download-sw
privileged EXEC command.
Archiving Software Images
Before upgrading your switch software, make sure that you have archived copies of the current Cisco
IOS release and the Cisco IOS release to which you are upgrading. You should keep these archived
images until you have upgraded all devices in the network to the new Cisco IOS image and until you
have verified that the new Cisco IOS image works properly in your network.
Cisco routinely removes old Cisco IOS versions from Cisco.com. See
Product Bulletin 2863

You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a
host by using the
copy flash: tftp:
privileged EXEC command.
Note
Although you can copy any file on the flash memory to the TFTP server, it is time consuming to copy
all of the HTML files in the tar file. We recommend that you download the tar file from Cisco.com and
archive it on an internal host in your network.
You can also configure the switch as a TFTP server to copy files from one switch to another without
using an external TFTP server by using the
tftp-server
global configuration command. For more
information about the
tftp-server
command, see the
Cisco IOS Configuration Fundamentals Command

Upgrading a Switch by Using the CLI
This procedure is for copying the combined tar file to the switch. You copy the file to the switch from a
TFTP server and extract the files. You can download an image file and replace or keep the current image.
Note
Make sure that the compact flash card is inserted into the switch before downloading the software.
