Hi, Yes, have the firmware at the same version. It is best to have no config and have it pull the config from the master.
Hello, I haven't worked with there Dell Power Connect switches in a while so figured I'd ask a couple of questions here. Currently have 3 stack members All are PC6224P models. I have a PC6248P unit which has a blank config on. It has the stacking module already inserted into the switch chassi and ready to go. I also have the stacking cable too. 1st question : Do I need to configure this PC6248P units configuration to match what's on the other 3 stack members or can I insert it with the black config so it can pick up the config from the stack master? I have no problem setting up the config manually but I figured I would ask here first. 2nd question :  firmware revision of 3.3.10.3 is what is on the 3 stack members . Should I be at the same firmware version on the PC6248P unit to avoid any weird problems? 3rd any other steps I should be doing here to get this to work correctly?   Thanks much!   Jose
