Hi, I've been trying to stack three switches a SG500-28P a SG500-52P and a SG500X-28P - the SG500s stack fine, however when I added the 500x to the stack, the unit deactivated itself and took itself off the network - not good as it was the core switch!
Any ideas what's going on, are they using a different stack protocol to the others - I was just going for native and 5G ?
Firmware was 1.3
Many thanks,
Chris
