Updating the Firmware on a Stack

Automatic Update

By default, firmware synchronization is performed autom atically when a unit is powered up on a stack.

Because firmware synchronization makes no attempt to check for the latest version of firmware, the

following procedure is recommended for bringing all members of a stack onto the same version of

code.

NOTE: Schedule some downtime as this process will reset the entire stack and affect all stack users.

1. Use the following commands to enable firmware synchronization, if needed, a nd write the

running configuration to the saved configuration:

console#boot auto-copy-sw

console#copy nvram:config copy system:running-config nvram:startup-

config

2. Load the more recent firmware image onto the stack master as the backup image.

3. Set the stack master to reboot from the new image:

console#boot system backup
