why reload is required to have the stack working.

Attached are my findings as i am not able to paste the data here.

Stacking port is showing down because you only properly connected one cable. 

When you are adding a new switch to a stack, make sure the new switch is POWERED OFF.  If you add a a powered up switch to the stack, the entire stack will reboot.

Leo,

Thanks for looking into this. I confirmed you that there is no problem wih the stack cable connection as the same setup worked fine after teh reload.

As said I double verified the cable and connection and all was okay.

I wanted to know the procedure/communication happens when i connect the new switch to the stack:

1- Power off the new switch

2- Connect the cables.

3- Power on the switch.

4- Exisiting switch will try to communicate internally to the new switch through stacking ports?

5- I need to know why I had to restart complete stack to have this work?

thanks in advance.
