Updating cisco ios switch 2960
The Catalyst switches originally ran software called Cat OS rather than the more widely known Cisco IOS software used by routers.
However, this has changed as the product lines have merged closer together.
After the switch is back up, do a show ver and verify that the switch is the same version as your existing stack. Now I’m going to go unplug the whole stack, change the stack module into the RMA switch, then turn everything back on at once.

Turn on the new switch and let it load the configuration that is default. Now change to the new flash as the boot system flash, save your settings to memory, and reload the switch: 15.
The Cisco IOS (Internetwork Operating System) is a robust platform that provides a high level of reliable performance within most network infrastructures.
My new switch needs the same IOS version as the old switches. Login to the old switches and run the command: show ver to find the version you need. I need to login to Cisco TAC and download version 15.0 (2) SE to my laptop. After the download is complete, I connect my laptop to my new switch on port 48 via ethernet cable. You can verify that this is the same as the old switch by running the command: show flash on the old switch and checking the latest firmware file date and matching it. Connect the Cisco terminal cable from your computer to the terminal port on the new switch.This backup should take place before any IOS image upgrade process start.In case of unsuccessful IOS image upgrade (due to too-small DRAM size, corrupted IOS image, etc.) it is always a good to know that you are able to reverse the change by putting back the older IOS image (the one that you backup earlier) to the router In order to transfer an IOS image typically you need to run a TFTP program on your computer.This FAQ assumes that your router is able to boot up normally.When your router is unable to boot up normally, please scroll down to the bottom of the page for suggestions.* Under any circumstances, DO NOT delete working IOS image off the flash memory unless the image has been backed up to server (TFTP or FTP server) or you have working IOS image stored in the server.Later description will show you how to back up the image* There is a chance that a router loses power or loses connection during the IOS image transfer (copy from or to server) which may cause the router to have no working IOS image to boot up from. Try the following* Backup image to TFTP server * Download image from TFTP server For those routers or switches that have USB port, you can use USB Flash drive to backup or to download IOS images as follows* Backup image to USB Flash drive * Download image from USB Flash drive Once you have both old and new IOS images in USB Flash drive, you can either save copies to your computer or to some storage such as DVD, tape backups, or some FTP servers.When such incident happens, you will be glad that you first back up the IOS image to server before deleting working IOS image off the flash memory. To transfer an IOS from PC to ROUTER, the following conditions must meet* The new IOS image file is in working condition since corrupted IOS image won't do any good* The new IOS image file is inline with the router DRAM and flash memory size.Select the "Bits per second:" drop-down box, and then choose the "9600" setting from thelink list that appears. After the IOS image file has been transferred to the Cisco WS-C2960S-48LPS-L, the switch automatically reboots and starts running the new IOS image.Select the "Flow Control" drop down menu, and choose the "None" setting in the list that appears. Enter "archive download-sw /overwrite /reload tftp:// IOS-file-name.tar" on the command prompt, substituting the "" with the actual name of the IOS update image file that is stored in the root directory of the TFTP service on the Windows 7 computer. I may know many different things in the IT realm, but when it comes to Cisco switching and IOS, I used to be clueless… When it came time to replace a Cisco 2960 switch and upgrade firmware, I was left cold. Phil specializes in datacenter technologies, including all things cloud, VDI, Info-Sec, and Vo IP.I didn’t feel like engaging our VAR this time, and instead, I put my time into figure out how to do it. (I’m assuming you have some basic knowledge of IOS like I have and have left out many generalized steps.) 1.
