DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide Switches in the series can be physically stacked using standard Category 6a cables with RJ45 connectors, optical fiber cables connected to SFP+ transceivers, or Direct Attached Cables (DAC) with SFP+ connectors. Only the last 4 ports can be used for physical stacking. Physical stacking needs to be enabled and can be configured to support either a 2-port or a 4-port stacking configuration. When the 2-port stacking configuration is used, a full-duplex speed of up to 40Gbps will be used between two Switches. When the 4-port stacking configuration is used, a full-duplex speed of up to 80Gbps will be used between two Switches. The figure below illustrates how Switches can be stacked in a Duplex Chain formation using Category 6a cables with RJ45 connectors where the 2-port stacking configuration is used. Figure 4-76Duplex Chain stacking topology (RJ45) The figure below illustrates how Switches can be stacked in a Duplex Chain formation using optical fiber cables connected to SFP+ transceivers or DAC with SFP+ connectors where the 2-port stacking configuration is used. Figure 4-77Duplex Chain stacking topology (SFP+) The figure below illustrates how Switches can be stacked in a Duplex Ring formation using Category 6a cables with RJ45 connectors where the 2-port stacking configuration is used. 83
