Figure 3-2. S60 Stacking Topology with 1-port, 24G Stacking Modules Ring Topology (with 1-port 24G modules) Cascade Topology (with 1-port 24G modules) 48 Switch 1 50 Switch 1 48 48 Switch 2 50 48 Switch 2 48 Switch 3 50 48 Switch 3 50 50 50 While the diagram shows A-to-B connections, the ports are bi-directional so you can connect A-to-A or B-to-B, as shown in the examples of two-switch ring topologies (Figure 3-4 or Figure 3-4) and three-switch (Figure 3-5 or Figure 3-6) ring topologies. Before you make your stacking port connections, rack-mount the stacking systems or insert them into a cabinet. Insert one end of the stacking cable into a stacking port and insert the other end into a stacking port of the adjacent switch. To ensure the cable is secure in the connector, hand-tighten all the captive screws. Connect Two S60 Systems 2-port, 12G Stacking Modules As an option, when using the 2-port, 12G stacking modules, insert a second cable into the other open stack ports (Figure 3-4). The second cable provides both backup connectivity and increased data transfer between the systems. To connect 2-port, 12G stacking modules, starting with the S60 at the bottom of the stack, follow these steps: Step Task 1 Insert one end of the first cable into Stack Port 48 (or 50). 2 Insert the other end of the cable into Stack Port 48 (or 50) of the top. 3 Insert a second cable into Stack Port 49 (or 51) of the bottom and top S60 systems.
