<div><p>Use this topic to select a method for starting your server and
handling problems with IPL.</p>
<p>Some changes to the system settings or hardware configuration require the iSeries™ server
to go through a startup sequence called an initial program load (IPL). During
an IPL, system programs load from the designated load source device in the
system auxiliary storage. The system hardware is also checked. The iSeries server
control panel displays a series of system reference codes that indicate its
current status and warn you of any problems. When the IPL is finished, the
character-based interface presents the sign-on display, and users will be
able to sign on with iSeries Navigator.</p>
<p>During the IPL, the control panel displays a series of system resource
codes (SRCs) indicating the current system activity.</p>
<p>There are various options for starting an iSeries server.</p>
