Connecting devices in a mixed stack
Topology 1: Single ring
In the figure below, two ICX 6610 devices form the backbone and there are three ICX 6450 peripheral devices. There can be up to six
ICX 6450 peripheral devices.
This is a single ring configuration in which the second ICX 6610 device is connected to the first ICX 6450 device, and the first ICX 6610
device is connected to the last ICX 6450 device. There is one substack that contains three peripheral devices.
FIGURE 34 Topology 1: single ring
Topology 2: Dual ring
In the following figure, two ICX 6610 devices form the backbone and there are six ICX 6450 peripheral devices in two rings. This is a
