8 Important Information
Updating Your System Packages Using
Red Hat Network
Red Hat periodically releases software updates to fix bugs, address security
issues, add new hardware support, and add new features. You can download
updated operating system packages and the latest kernel releases from
rhn.redhat.com by using the Red Hat Network (RHN) service on your system
or by using the yum utility. Dell recommends that you use the RHN service
to update your system software to the latest revisions before you deploy your
system for the first time.

Dynamic Host Configuration Protocol (DHCP). To change network settings,
go to Red Hat Main Menu→ System Settings→ Network and follow the on-
