Stacking a HP 2530 48 port switch with a 24 port

[eddiescarberry]

I have a mix of HP 2530 switches, 24 port and 48 port.  I am having issues stacking a 48 port with 24 port.  I have 48 port switches stacked sucesfully.  When I stack a 24 with a 48 port, it stacks sucessfully, but when I attempt to access the 24 port in the stack or do a stack view, I get a time out error and errors about EWA.   Any suggestions?
