Controller Cluster I/O Ports
The controllers provide three redundant cluster links: two serial links and an Ethernet link. For the location of these cluster ports, see the hardware overview for the appropriate controller.
The following diagram illustrates the cluster serial and Ethernet ports for ZS5-4, ZS5-2, ZS4-4, ZS3-4, and 7x20 controllers.
