Do I need to install Java before installing PowerChute Network Shutdown?
PowerChute Network Shutdown
All supported OS
If you go to https://www.apc.com/tools/download/ and choose Software Upgrades - PowerChute Network Shutdown from the drop-down list, PDF documents listing supported JREs can be found.
PowerChute Version 4.3
With all supported operating systems except HP-UX®, AIX™, and Mac OS XTM, PowerChute installs a "private" JRE during an installation.
To install PowerChute on HP-UX, AIX, and Mac OS X, a compatible JRE must already be installed on your system.
Solaris Sparc gives you the option of installing the bundled JRE, or specifying a JRE location.
PowerChute Version 3.x, and 4.0, 4.1, 4.2
With all supported operating systems except HP-UX, AIX, and Mac OS X, PowerChute gives you the option of installing a "private" JRE during installation.
However, this "private" version of the JRE, which is specifically for PowerChute, will take up about 100 MB of disk space. A PowerChute installation takes up about 6 MB of space if you have already installed a public JRE.
PowerChute Version 2.2.x
For v2.2.x, the answer varies with the operating system.
On the non-Itanium versions of Windows, PCNS has a bundled JRE 5.0 Update 13. It has to determine whether it installs JRE or uses a version already installed on your system. Please refer to KBase answer ID #9926 for details.
On Linux, VMware, and Solaris for Sparc, PCNS also has bundled JRE version. It gives you a choice whether or not to install the bundled JRE or use a JRE installed on your system. A supported JRE is listed in the Compatibility Chart for PCNS on the APC Web site.
On HP-UX, AIX, NetWare, Mac OS X, and Itanium Windows, Solaris 10 for x64/ x86 , PCNS does NOT install JRE. You must make sure that a compatible JRE version is already installed on your system before you install PowerChute Network Shutdown.
For most operating systems, you can download a Java Runtime Environment from https://java.sun.com. NetWare 6 has JRE 1.3.1. Other versions of JRE are available on Novell's Web site.
