DGS-3630 Series Layer 3 Stackable Managed Switch Hardware Installation Guide The figure below illustrates how switches can be stacked in a Duplex Ring formation using optical fiber cables connected to SFP+ transceivers or DAC with SFP+ connectors where the 2-port stacking configuration is used. Figure 4-4 Duplex Ring stacking topology (SFP+) NOTE: Stacking Input/Output 1 (SIO1) is a logical stacking port pair. SIO2 is also a logical stacking port pair. A logical stacking port pair must always be connected to the same Switch in the stack. Splitting logical stacking port pairs between different Switches in the stack might not guarantee a stable stacking connection. 34

NOTE:
Stacking Input/Output 1 (SIO1) is a logical stacking port pair. SIO2 is also a logical stacking port
pair. A logical stacking port pair must always be connected to the same Switch in the stack. Splitting
logical stacking port pairs between different Switches in the stack might not guarantee a stable stacking
connection.
