Hi,

Hi,

The other cable is the stacking cable for power.  You can power up switches by daisy chaining them together (see figure-7 in this link).

As for data stacking make sure you are cross connecting them together.  (see the same link).

If you want one switch to be the master, give it a higher priority.  1 is the worst and 15 is the best. So give it 15.

Reza is correct.  Bottom

Reza is correct.  Bottom cable is your data stacking cable.  Out of the box the 3850's will stack automatically.  The stack master will be elected unless you give one a higher priority like Reza mentioned.  The show switch command will give you details about the stack.  

I just setup 2 switch stacks of 3850's last week.  Here is what I did.  Powered on the switch I wanted to be the stack master.  Then configured stack priority with the following:

Switch# switch 1 priority 15

Then connect the stacking cables to the two switches and power on the second unit.  After about 8 minutes when it finally boots up you should see it join the stack!
