Stacking From firmware release v1.00 of this Switch, the Switch now supports switch stacking, where a set of 12 switches can be combined to be managed by one IP address through Telnet, the GUI interface (web), the console port or through SNMP. Each switch of this series has two stacking ports located at the rear of the device, which can be used to connect other devices and make them stack together. After adding these stacking ports, the user may connect these ports together using copper cables (also sold separately) in one of two possible topologies. Duplex Chain - As shown in Figure 2-22, The Duplex Chain topology stacks switches together in a chain-link format. Using this method, data transfer is only possible in one direction and if there is a break in the chain, then data transfer will obviously be affected. Duplex Ring - As shown in Figure 2-23, the Duplex Ring stacks switches in a ring or circle format where data can be transferred in two directions. This topology is very resilient due to the fact that if there is a break in the ring, data can still be transferred through the stacking cables between switches in the stack. 24
