3850 stack member has no mac address.

I have a strange issue where a member in my 3850 stack has no mac address.  This occurred after at duplicate address was discovered on the management interface.  We have reboot the switch but no luck. still the same. see below:

BTRBRGBB1535A_Stack1#sho sw de

It's not "strange".  It's a normal behaviour because the 2nd stack member hasn't joined the stack yet.  It could be the that the 2nd stack member isn't powered up or it's not cabled properly.
