DXS-3610 Series Layer 3 Stackable 10GbE Managed Switch Hardware Installation Guide
In the following diagram, switches are stacked in the Duplex Ring topology.
Physical stacking needs to be enabled and can be configured to support a 2-port, 4-port, or 6-port stacking
configuration. SIO1 (Stacking Input/Output 1) and SIO2 are logical stacking port pairs. 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.
The following table lists the stacking configuration with the corresponding SIO port pairs:
