Cisco 3750x stacking issue

I have 4 Cisco 3750X's connected via stacking cables.  The last switch in the stack, does not see itself as a member of the stack for some reason.  I've verified that the cabling is correct and rebooted the stack several times but the problems persist.  The switch will boot up, call itself the master (even though there is already another master) and then it looks like it reboots. It keeps going through this cycle. Any ideas?

you might want to check the priority level on the switch that is rebooting on you, it might want to become the master in the stack, remove it from the stack and have it as a stand alone, console into it and change the priority.

look at the version of code on the switches, if the version of code is too far apart they will not join a stack.

you might have to manually update the code to match the rest of the switches.

you also probably want to pay attention to which version of the code you have on all of the switches to make sure they are similar features. SMI or EMI.

hope this helps.
