IP Subnet Requirements
Table 4-2 lists the separate IP subnet requirements for systems with U772 Ethernet
switches.
Table 4-3 lists the minimum separate IP subnet requirements for systems that do not
include U772 Ethernet switches.
Table 4-2. IP Subnet Requirements With U772 Ethernet Switches
System Configuration Separate IP Subnets
ftServer system with an
optional network
I/O enclosure
One subnet in the form 10.10.1.0/24 to connect the host
system to the U772 Ethernet switches. See ‘‘Maintenance
Network’’ on page 4-2 for more information.
A second subnet in the form 10.20.1.0/24 to connect the
host system and the network I/O enclosure.
Additional subnets to connect the host system to site
networks
ftServer system without an
optional network
I/O enclosure
One subnet in the form 10.10.1.0/24 to connect the host
system to the U772 Ethernet switches. See ‘‘Maintenance
Network’’ on page 4-2 for more information.
Additional subnets to connect the host system to site
networks
Table 4-3. IP Subnet Requirements Without U772 Ethernet Switches
System Configuration Separate IP Subnets
ftServer V 100, V 200, or
V 400 system with optional
network I/O enclosure
One subnet in the form 10.10.1.0/24 to connect the host
system and the network I/O enclosure. The Ethernet ports
on the UPS units and the RSN console server are
connected to this subnet.
A second subnet to connect the host system to a site
network
ftServer V 100, V 200, or
V 400 system without
optional network
I/O enclosure
Two subnets in the form 10.10.10.0/24 and 10.10.11.0/24
to connect the host system to the two UPS units
A third subnet in the form 10.10.1.0/24 to connect the host
system to the RSN console server
Additional subnets to connect the host system to site
networks
