1. Before stacking a switch a few things of note:
Afterward there is a series of commands you can run such as:
The link of http://www.cisco.com/c/en/us/products/collateral/switches/catalyst-3850-series-switches/deployment_guide_c07-727067.html is a good place to start.
You should first do a back up of the existing soon to be master switch.
You can stack while the master is online.
The switches should be exact same type.
The switches must have the exact same running IOS. If not you need to make them the same. Failure to do so will result in it not working can can cause an outage or corrupted IOS. A good command is show platform stack-manager all
They should be stacked one at a time.
Afterward there is a series of commands you can run such as:
show switch
show switch detail
show switch neighbors
show switch stack-ports

Ok.
Can you first provide the following on the single master switch that is currently online.
show switch
show switch detail
show switch neighbors
show switch stack-ports
Post the response afterward.

with stack you'll gain a configuration where you'll be able to comfigure and see all of your stacked switches as a unique switch with all the ports summed up.
I do not know if you have a particular doubt on configuration but i believe the best thing is to read the deployment guide and figure out how you want them to work.
