v If the PC uses Operation Console as a local console directly attached to the system, a network
connection for System i Navigator is required. To complete the System i connection, the system needs a
network adapter and a configured i5/OS line description (LIND).
Operations Console is connected over a serial cable attached to an asynchronous card on the System i
platform. System i Navigator is connected through a LAN adapter on the System i platform. The PC
communicates to Operations Console through its communication port while communicating with
System i Navigator through the LAN connectivity.
Figure 2. System i Navigator and Operations Console configuration over separate connectivity
The PC used as a local console on a network might require an additional network connection. System
v
i Navigator requires a network connection to the network adapter and configured i5/OS line
description. Operations Console uses the service network adapter as defined by the service host name
(interface name). If the network adapter and configured i5/OS line description and the service network
adapter as defined by the service host name (interface name) are on the same network, an additional
PC LAN adapter is not needed. This is illustrated in the following figure.
