3750 stack switch replacement.

Hi,

We need to replace one of the stacked switch out of 4 stacked 3750s. The switch we need to replace is not the master switch. Can we do it  by powering down only that switch, remove the stack cables replace it with new switch put back the stack cables and power on the switch.

1. connecting the stack cables while adjacent switches those are powered on is it a risk? Or do we need to power off all switches from the stack and then replace the device.

2. The configuration for that switch will be automatically taken from the master switch?

Please share the experience.

Thanks

Re: 3750 stack switch replacement.

Hi Subodh,

follow the instruction in this link to add a switch to your stack:

http://www.cisco.com/en/US/products/hw/switches/ps5023/products_configuration_example09186a00807811ad.shtml#stack3

  1. Change the switch priority of the switch to be added to "1".

    switch stack-member-number priority new-priority-value

    Note: This step is optional, but it will make sure that the switch has fewer chances to become a stackmaster in the future.

  2. Power off the switch that is to be added.

  3. Make sure that the stack is fully connected so that, when you connect the new switch, the stack will be at least in half connectivity and does not partition.

  4. Connect the new switch to the stack with the StackWise ports.

  5. Power on the newly added switch.

  6. After the new switch comes up, issue the command show switch to verify stack membership.
