Internal Networks
The subnets for the internal networks are fixed. Because I1, which is the domain to
system controller management network (that is, MAN), and I2, which is the system
controller to system controller management network, are not routed, the IP networks
can be taken from the IP private pool. These networks should be set up using
automatic assignment of host names and IP addresses. The networks should be
unique within the customer network.
External Networks
Enter the IP network address and subnet mask in
TABLE 5-4
. The subnet mask must
be unique within the network. The system controller can connect only to one user
community. These addresses are set when you configure the system controllers.
System Controller
IP addresses are required for every interface on the system controller (SC) that is
cabled to a user community. Both SCs have one built-in Ethernet port (labeled
“Ethernet”) cabled, and the other port (“Ext Ethernet”) is not used in this
configuration.
