OL-21141-03
Upgrading the Switch Software
Catalyst 3750 or 3560 switches with a 16-MB flash memory can experience problems due to flash
memory constraints, especially if they are using larger size images, such as c3750-ipservicesk9-tar,
c3560-ipservicesk9-tar, c3750-ipbasek9-tar, or c3750-ipbasek9-tar images. These are the affected
switches:

c3560-ipservicesk9-tar, c3750-ipbasek9-tar, or c3750-ipbasek9-tar images. These are the affected
switches:
Catalyst 3560: WS-C3560-24PS and WS-C3560-48PS
Catalyst3750: WS-C3750-24PS, WS-C3750-24TS, WS-C3750-48PS, WS-C3750-48TS,
WS-3750G-24T, WS-C3750G-12S, WS-C3750G-24TS, WS-C3750G-16TD
WS-3750G-24T, WS-C3750G-12S, WS-C3750G-24TS, WS-C3750G-16TD
The workaround for these switches is to use the corresponding lm images, such as the
c3750-ipserviceslmk9-tar or c3560-ipserviceslmk9-tar images, which require less memory. In future
releases, images are expected to grow more in size, requiring more need for the lm images.

Catalyst 3750G Integrated Wireless LAN Controller Switch Software Compatibility
The Catalyst 3750 Integrated Wireless LAN Controller Switch is an integrated Catalyst 3750 switch and
Cisco 4400 series wireless LAN controller that supports up to 25 or 50 lightweight access points. The
switch and the internal controller run separate software versions, which must be upgraded separately.

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.
