Control network through an Avaya Ethernet switch
When designing S8700-series fiber-PNC systems, a control network connects the servers to
the IPSIs through a 10/100 BaseT Ethernet. It consists of two separate Ethernet networks using
Ethernet switches. Control network A connects to the primary IPSIs, and control network B
connects to the secondary IPSIs (Figure 22:
S8700-series fiber-PNC control network).
