DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide
82
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.

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 4-76 Duplex 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.
