Chapter 1
Understanding Basic Hardware Architecture and Cisco IOS Software
Upgrading to a New Cisco IOS Release
Note
If you have available space for two images, leave both images in Flash memory. If necessary,
you can easily revert back to the previous image. Enter the boot system flash newiosname.bin
command to point to the new image filename. By default, the first image in Flash memory is
loaded.
If you do not have available space, during the copy operation the system displays a message
telling you to delete the current file and squeeze the flash to make room for the new image. Enter
the delete flash:version command, followed by the squeeze flash command, to perform this
delete-and-squeeze operation. Then proceed with the copy operation.

Caution
Occasionally TFTP errors occur. Make sure that the verifying checksum reports “OK.” Do not reload the
gateway if the checksum reports errors.
Step 3
Verify that the new image was downloaded. In this example, notice that the Cisco IOS Release
12.1(1)XD image is the first in Flash memory, so it is loaded during the boot sequence. To boot using
the new image, you must either delete the unwanted image or use the boot system command to specify
the alternate image to use during the boot sequence.
Router# dir flash:
Directory of flash:/
1 -rw- 9950528 Jan 01 2000 00:48:59 c5350-js-mz.121-1.XD1.bin
2 -rw- 9775616 Jan 01 2000 00:59:10 c5350-js-mz.121-3.T.bin
32768000 bytes total (13041600 bytes free)
For more information on deleting the image, refer to the document Cisco IOS File System, available

Note
The Cisco AS5350 and Cisco AS5400, unlike the Cisco AS5200 and Cisco AS5300, use a
Class A Flash File System.
