DGS-1520 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide Appendix G - Stacking Information The following stacking topologies are supported on the Switch: • Duplex Chain - This topology stacks switches together in a chain-link format. Using this method, data transfer is only possible in one direction. If there is a break in the chain, data transfer will be affected. • Duplex Ring - This topology stacks switches in a ring or circle format where data can be transferred in two directions. It is very resilient because if there is a break in the ring, data can still be transferred through the stacking cables between switches in the stack using the alternate path. In the following diagram, an even number of switches (for example 4 switches) are stacked in the duplex chain topology using the 2-port stacking configuration through the two 10GBASE-T ports.
