Updating firmware on a stack

Note: Make sure to check the Release Notes and any special instructions that may have come with new
firmware updates. It is important to follow instructions found in those documents if they deviate from
this white paper.
Steps for upgrading the firmware on a stack of switches are similar to upgrading the firmware on a single
switch. Whether downloading a new image to the Master by using the System > File Management > File
Download page in the Web UI, or the copy command in the CLI, the downloaded image is distributed to
all member units of the stack. The instructions below guide the user through these steps.

Each member of the stack is updated with the latest firmware simply by updating the Master switch. The
commands below demonstrate how to copy the firmware file down to the Master using a TFTP server.
The stack needs access to the TFTP server on the network and the firmware file needs to be present in the
download folder of the TFTP server. Perform the following command from the CLI interface. Press "y"
when prompted.
console#copy tftp://10.10.1.10/N4000v6.0.1.3.stk backup
