Stacking Dell PowerConnect 7000 Series Switches
Updating the Firmware on a Stack
Automatic Update
By default, firmware synchronization is performed automatically 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. Enable firmware synchronization using the boot auto-copy-sw command if needed. Write
the running configuration to the saved configuration.
2. Load the more recent firmware image onto the stack master.
3. Set the stack master to reboot from the new image using the boot system image command.
4. Reload the stack using the reload command. This resets the entire stack.
5. When the stack has reloaded, check the running firmware version using the show version
command. Check that all stack members have joined the stack using the show stack
command. Members that failed to update may be recovered using the manual update
procedure described in the following section.
6. If successful, disable firmware synchronization on the stack and save the running configuration.
