5520 Switch stack
« on: January 06, 2020, 12:29:48 PM »
Hi everyone

I have a four switch stack which is running firmware with software v6.2.3.010.

One of the switches developed a fault and is now offline so needs replacing. I now have a new switch with software v6.2.3.011. Would I be ok installing this switch with different software?

Also, do I need to put any configuration on the replacement switch or will it sort itself out after a stack reboot?

Many thanks for your advice

Hi Balcee.

Use the following command line configuration to set stack options. You have to be in "config" mode. Type "stack ?" and you will see the options listed below.

Stack related commands
  auto-unit-replacement            Set auto unit replacement settings
  auto-unit-replacement-image  Set auto unit image replacement settings
  forced-mode                          Enables the forced stack mode
  reboot-on-failure                    Reboot stack units when their stacking ports fail to come up
  replace                                  Replace a stack member that is down
  retry-count                            Configure stack retry count

Enable auto-unit-replacement and auto-unit-replacement-image.  If these don't work, manually upgrade the replacement switch, add it to the stack and use the stack replace command.
