<h4 id="rzajt-cfg400to3174-rf">Match iSeries system parameters for a 3174 controller</h4>
<p>You must match the iSeries&trade; configuration parameters with the configuration
questions and sequence numbers to configure the 3174 controller. These parameters
are described in the following table.</p>
<p>For more information about configuring the 3174 controllers, see these
books: </p>
<ul>
<li><cite>3174 Subsystem Control Unit
Customizing Guide</cite></li>
<li><cite>3174 Establishment Controller
Supplemental Customer Information for Configuration Support C Release 4 Ethernet
Attachment</cite>, GA27-3994 has information
about Ethernet support.</li></ul>
<p>To configure the iSeries server to a 3174 controller:</p>
<ul>
<li>See <a href="rzajtrzajtcfg400to3174exre.htm#rzajt-cfg400to3174ex-re">Example: iSeries server connection to a 3174 control unit</a> for an example of connecting
an iSeries server to a 3174 remote controller.</li>
<li>Use the following table to connect an iSeries server to a 3174 remote controller.</li></ul>
