Release Notes for the Catalyst 4500 Series Switch, Cisco IOS Releases 15.2(2)Ex

Upgrading the System Software

To upgrade the Cisco IOS software on your Catalyst 4500 series switch, use this procedure:

Step 1

Download Cisco IOS Release 15.1(2)SG from Cisco.com, and place the image on a TFTP server in a
directory that is accessible from the supervisor engine that is upgraded.

Step 2

Use the dir bootflash: command to ensure that there is sufficient space in Flash memory to store the
promupgrade image. If there is insufficient space, delete one or more images, and then enter the
squeeze bootflash: command to reclaim the space.

If you are using a CompactFlash card, use slot0: instead of bootflash.

Step 3

Download the software image into Flash memory using the copy tftp command.

The following example shows how to download the Cisco IOS software image
cat4000-is-mz.121-12c.EW from the remote host 172.20.58.78 to bootflash:

Switch# copy tftp: bootflash:

Address or name of remote host [172.20.58.78]?

Source filename [cat4000-is-mz121_12c.EW]?

Destination filename [cat4000-is-mz.121-12c.EW]?
