To stack the PowerConnect 6200 series switches, do the following.
1. Power off the switches and install the stacking module into the first slot on the left in the back of the switch.
2. The following commands changes the modes for the interfaces, and then reboots the switch.
console#config
console(config)#stack
console(config-stack)#stack-port 1/xg1 stack
console(config-stack)#stack-port 1/xg2 stack
console(config-stack)#end
console#copy running-configuration startup-configuration
console#reload
Update each switch to the latest firmware using the instructions.
Power off the switches. For each switch in the stack, connect one of the stacking cables from stack port one on the switch to stack port two on the next switch. On the last switch cable port 1 to port 2 of the first switch in the stack.
3. Power on the desired primary switch first. Afterwards power on the next switch one at a time until every switch is powered on.
console#show switch will show the switch status, firmware code, and number of switches in the stack. Use this to verify stacking.
