IOS upgrade on Cisco Switch in Stack

Upgrading Cisco switch in stack :
The .bin file is the Cisco IOS Software image. If you want to use only the CLI to manage the switch, this is the only file you need to download. To upgrade follow this steps: 1. Download the bin image from the cisco.com website. 2. Issue the dir flash: command to verify the amount of free memory that you have for the upgrade. 3. Copy the bin image to the flash of each switch. In this case, two are the switches so the commands are: copy ftp: flash1: copy ftp: flash2: 4. Configure the boot variable to boot the switch with the newly copied IOS: boot system switch all flash:/c2960s-universalk9-mz.150-2.SE5.bin

5. enter "reload" command from Master Switch. All stack members will be reloaded.

Note: if you just issue the reload command from the master, the whole stack will reboot. The reload slot [id] will reload a single switch.
