connects stacking members from one to the next. This provides a single data path flow. The 
stacking members linked in the middle of the chain are connected to the stacking member on either 
side of them. The members at the end of the chain only have one connection.
Stacking Ring Topology
One of the benefits of the Ring topology is that it offers redundancy in case the connections 
between two units fail, including the case where a unit in the stack fails. If a failure occurs in the 
stacking topology, the stack reverts to the Chain stacking topology. In the Chain topology, devices 
operate in a chain formation. The system automatically switches to a Stacking Failover topology 
without any system downtime. An SNMP message is automatically generated, but no stack 
management action is required. However, the stacking link or stacking member must be repaired 
to return to the Ring topology. 
After the stacking issues are resolved, the device can be reconnected to the stack without 
interruption and the Ring topology is restored.
Stacking Ports
The mode type determines the Gigabit Ethernet ports that are configurable by the user.
In Standalone mode all Gigabit Ethernet ports are available.
In Stack mode two dedicated Gigabit Ethernet ports are used for stack connection.
The factory default of the device is stack mode. Use the System Information screen to change the 
unit mode from Standalone to Stack mode.
The ports used for stacking can be either the combo ports or the copper ports. By default, the 
copper ports are reserved for stacking. The Stack Management screen allows network managers to 
configure the combo ports as the stacking ports. 
Two full-duplex stacking link up/down ports are available via HDMI connectors and provide 10 
Gps throughput stacking capacity.
Stacking Members and Unit No.
Stacking Unit Numbers are essential to the stacking configuration. Unit No. 1 and Unit No. 2 are 
reserved for Master enabled units. Unit Numbers 3 to 6 can be defined for stack members. When 
the Master unit boots or when inserting or removing a stack member, the Master unit initiates a 
stacking discovering process.
If two members are discovered with the same Unit No., the stack continues to function. However, 
only the unit with the older join time joins the stack. A message is sent to the user, notifying that a 
unit failed to join the stack.
