PS3000 Series Hardware Maintenance Maintaining Control Modules

For a dual control module array, the minimum network configuration is a network
connection to Ethernet 0 on both control modules. Although this configuration
protects against control module failover, it is still a potential point of failure (for
example, if the network cable connected to the active control module is
disconnected). Therefore, it is recommended that you connect multiple network
interfaces to different switches.
Figure 3-5 shows the minimum network configuration for a dual control module
PS3000 Series array. Cables are connected to Ethernet 0 on both control modules.

Figure 3-6 shows the recommended network configuration for a dual control
module PS3000 Series array. This configuration provides the highest network
availability and the maximum network bandwidth.
