Step 1 - Download the .tar Image
You need to make sure you have sufficient space available in the Flash of the master switch. The master switch should have twice the amount of space of the .tar image file size. This space is needed to store the .tar file as well as to store the content of the .tar file that you extract in step 2. For example, if the .tar image size is 10 Mb, you need to have a minimum of 20 Mb of free space.
3750-stack#copy tftp: flash:
Address or name of remote host []? 10.10.10.10
Source filename []? c3750-advipservicesk9-tar.122-25.SEE1.tar

Loading c3750-advipservicesk9-tar.122-25.SEE1.tar from 10.10.10.10 (via Vlan10
): !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!--- Output is suppressed.
Step 2 - Extract the .tar Image
Extract the .tar images to all the switches in the Flash file system. The archive tar /xtract command creates a directory and extracts the files under the newly created directory.
This is an example of the command syntax:
3750-stack#archive tar /xtract <tar file name> <Dir to extract files>
Complete these steps:
- Extract the .tar file into the Flash on switch1.
- 3750-stack#archive tar /xtract c3750-advipservicesk9-tar.122-25.SEE1.tar
- flash1:

- !--- Output is suppressed.
Step 3 - Configure the Boot Variable
After you extract the .tar files into the Flash, you need to configure the boot variable to point to the new IOS. You need to find the path where the .bin file is extracted.
3750-stack#dir
Directory of flash:/
2 drwx192 Mar 11 1993 00:31:05 +00:00 c3750-advipservicesk9-mz.122-25.SEE1

3750-stack#
The boot system switch all command is used to change the boot variable.
Note: This boot system switch all has been brought down to a second line due to spatial considerations.
3750-stack(config)#boot system switch all flash:/c3750-
advipservicesk9-mz.122-25.SEE1/c3750-advipservicesk9-mz.122-25.SEE1.bin
3750-stack(config)#exit
3750-stack#write memory
Step 4 - Reload and Verify
Reload the switch and verify that the switch runs the new Cisco IOS software release after the reload:
!--- Reload the switch.
Switch#reload
Proceed with reload? [confirm]
!--- Verify the Cisco IOS software release of the switch after the reload.

3750 Series Switch Stack IOS Upgrade - Manual (.bin Image)
A 3750 switch stack can be managed either with the web device manager or with the CLI. If you manage the switch with the CLI, you do not need the .tar image. This section explains the IOS upgrade with the .bin image. It is assumed that you have already configured the 3750 switch stack with an IOS image. This section explains how to copy and upgrade the new IOS in the 3750 switch stack.
This example explains the step-by-step procedure to upgrade the IOS to Cisco IOS Software Release 12.2(25)SEE2 on a Catalyst 3750 switch stack. The Catalyst 3750 switch stack has two switches and the IOS image is located at the TFTP server 172.22.1.165. This output shows the stack member and the master in this stack:
Switch#show switch
Current
Switch# Role Mac Address Priority State
--------------------------------------------------------
1 Member 0015.63f6.b700 5 Ready
*2 Master 0015.c6c1.3000 10 Ready
Step-by-Step Instructions
Step 1 - Download the .bin Image
Refer to Software Download - Cisco Catalyst 3750 Software 
( registered customers only) and find the image that you want to download. The Software Download Center for the Catalyst 3750 contains two sets of IOS images for every feature set and versions. One set contains only the IOS image file which has the extension .bin. The other set contains the IOS image plus the web-based device manager which has the extension .tar.
Step 2 - Verify the Available Memory
You can verify the available memory in the Flash file system of both switches individually as this example output shows:
Switch#dir flash1:

In a Catalyst 3750 switch stack, flash: represents the Flash file system of the master switch. In this example, the dir flash: command displays the contents of the master switch (Switch 2) which is flash2:.
Step 3 - Copy the Images to the Flash File System
Copy the .bin image from the TFTP server to the Flash file system of both switches.
Note: The Automatic Upgrade (auto-upgrade) feature only works with .tar images.
Switch#copy tftp: flash1:

Step 4 - Configure the Boot Variable
Configure the boot variable to boot the switch with the newly copied IOS:
Switch(config)#boot system switch all flash:/
c3750-advipservicesk9-mz.122-25.SEE2.bin
Switch(config)#exit
Switch#write memory
Step 5 - Verify Before the Reload
Verify the boot variable:
Switch#show boot
BOOT path-list : flash:/c3750-advipservicesk9-mz.122-25.SEE2.bin
!--- Master switch.
Config file : flash:/config.text
Private Config file : flash:/private-config.text
