Add non-flex switch to existing switch stack

[jalain_cisco]

I have an existing stack consisting of two CISCO 2960-S series switches. They are connected using the flex-stacking cables in the back, the top one being the master and the lower being the slave.

I have a 3rd switch, slightly different model, just a plain 2960 series that I'd like to add to the existing stack as a slave. It does not have a flex stacking option/does not have those cables in the back.

So my question is straight forward. Can I still add this switch as a slave? If so, are there any diagrams or guides to help out? I'm unfamiliar with which ports should be connected where and what commands may need to be run.

Thanks,

There is no physical way to add a plain 2960/G to a 2960S/X/XR stack using FlexStack. 

The only "method" is to use a very archaic method of stack called "Switch Stacking".
