Figure 66. Inter-rack switch connectivity - linear topology (daisy-chain) between EX Series racks
The inter-rack linear topology between an EX-Series rack and a Gen2 rack is shown in the following figure. For a mixed Gen2
and Gen3 environment, use Turtle switch port 51 for inbound, and port 52 for outbound. On the Gen3 Fox switch, use port 39
for inbound and port 40 for outbound. This is a requirement for mixing Gen2 and Gen3 racks in the same VDC. Ports 39 and 40
are not used in an all Gen3 environment with EX-Series racks.

Ring topology
For a more reliable network, the ends of the daisy chain topology can be connected together to create a ring network as
demonstrated below. The ring topology would require two physical link breaks in the topology to create split-brain issue in the
private.4 network.
