Stacking Features (PCM6220 and PCM6348 Only)
PowerConnect M6220 switches can be stacked only with other
PowerConnect M6220 switches. PCM6220 and PCM6348 switches cannot be
combined within the same stack.
For information about creating and maintaining a stack of switches, see
"Managing a Switch Stack" on page 135.
High Port Count
You can connect up to 12 PowerConnect M6220 switches or 12
PowerConnect M6348 switches in a single stack to increase the port count.
Single IP Management
When multiple switches are connected together through the stack ports, they
operate as a single unit with a larger port count. The stack operates and is
managed as a single entity. One switch acts as the master, and the entire stack
is managed through the management interface (Web, CLI, or SNMP) of the
Automatic Firmware Upgrade for New Stack Members
If a switch is added to a stack, and the switch is running an older version of
the firmware than the other stack members, the firmware on the new member
is automatically upgraded to match the stack.
Stacking Compatibility with the PowerConnect 7000 Series
PowerConnect M6348 switches and PowerConnect 7000 Series switches can
be members of the same stack. The stack can contain any combination of
switch models in the PowerConnect 7000 Series and M6348 switches as long
as all switches are running the same firmware version.
