PowerConnect M6220 Stacking
You can stack up to 12 PowerConnect M6220 units, supporting up to 240 1-Gb ports. Create a stack by
connecting adjacent units using the stacking ports on the top of the switch panel. See Figure 4-5.
1. Install a separately purchased stacking module in Bay 1 of each of the switches in the stack.
2. For each switch in the stack, connect one of the short stacking cables from stacking port one on the
switch to stacking port two on the next switch.
3. If necessary, use a separately purchased, long (3 meter) stacking cable to connect the switches. Repeat
this process until all of the devices are connected.
4. Use the remaining stacking cable to connect the remaining free ports, from port one of the last switch
to port two of the first switch.
