Cautions
• IP numbers reserved for private Internets by the Internet Assigned Numbers
Authority (IANA) can be used to initially configure the ClearPath IX server; but
to connect to the external Internet in the future, the site must get official IP
addresses and then reconfigure all ClearPath IX server components with those
addresses.
• A site must not use numbers in the range 192.168.57.xxx. Unisys has
selected numbers in that range for the ClearPath IX server’s internal FDDI LAN
(see Appendix B).
A suggested methodology for using addresses reserved for private LANs is to use Ethernet
IP addresses in the range 192.168.58.xxx. That ensures that the Ethernet addresses identify
a different LAN segment from the internal FDDI LAN, which uses numbers in the range
192.168.57.xxx. Figure 2–1 and Table 2–4 illustrate the connection of server components
to the Ethernet network, and IP addresses that could be assigned, using that methodology.
In addition, the site also must reconfigure CMS 1100 to support IP addresses for the 2200
node and system consoles (see 16.2).
Note: Figure 2–1 and Table 2–4 show the use of this methodology with single-node
systems only.
