•The FS524S Switch has two bi-directional stacking ports, which allow load-balanced, fault-tolerant, redundant connections when cascaded with another FS524S Switch. Up to eight FS524S Switches can be cascaded, providing up to 192 ports in a single switched stack. The high-speed stacking ports deliver 4 Gbps of throughput across the stacking back plane.
To add gigabit connectivity, two FS517TS Switches can be added to the stack to create one large virtual switch with up to 224 stacked ports and two 1000BASE-T ports. Since the FS517TS Switch has a single stacking port, adding it to a stack of FS524S Switches reduces the stacking backplane speed to 2 Gbps and removes support for load balancing, fault tolerance, and redundancy that a pure FS524S stack has.
