10.2 Software Updates
Updates to Concurrent RedHawk software can be obtained via Concurrent’s Software Portal.
There are three ways of installing product updates:
• Using the Network Update Utility (NUU) installed on your RedHawk system
• Manual installation after browsing and downloading individual RPMs from Concurrent’s
software repositories
• Building a customized Update disc using Concurrent’s web site for immediate download
10.2.1 Updating via NUU
NUU supports installation and updating of software products from Concurrent software
repositories over a network. NUU utilizes Yum and the RPM subsystems to install and
update software.
NUU is installed automatically with RedHawk, however, you should configure it to include
all of the Concurrent software products installed on your system.
Clicking on the “Updates (NUU)” icon on your desktop launches NUU to check to see if
Concurrent updates are available for your system.
Instructions for configuring NUU can be found in the QuickStart.pdf document available
at
http://redhawk.ccur.com/updates/QuickStart.pdf.
The first time you invoke NUU you will need to specify your redhawk.ccur.com Login ID
and Password that were provided in the shipping documents accompanying your system. If
you require assistance, refer to “Direct Software Support” on page 83.
Before using NUU to install any updated software modules, check for NUU updates
separately. Apply any NUU updates and then restart NUU before applying any other
updates.
