Configuration Set Management
The top of the Configurator menu (page 5−9) shows the name of the selected set. This is the system configuration directory
that is currently selected for editing.
After a set is edited, it should be saved and then compiled. If compiling is successful, the set name will appear on the Jupiter
Network Suite Control Center “Application” menu; the set can then be selected for downloading, during which a copy is
sent to the system hardware. Another copy always remains in the server, ready for automatic, on−demand download to the
hardware.
The Jupiter can have any number of configuration sets, each of which contains the file and subset types shown on page 5−12.
(The files in quotation marks are example names.)
Any one of the configuration sets can be selected for use by the system. This allows the entire system to be reconfigured from
the file server with only a brief interruption to normal operations.
Modifying and Downloading a System Configuration Set
Quick Start tip: Program the system in small steps and compile often!
As described earlier, a compiled and/or active configuration set cannot be edited directly. And, since creating a new configura-
tion set from scratch is a very time−consuming process, you will probably want to make changes by making a copy of the
uncompiled (source) version of the set, editing it, and then switching the new set on−line. While any number of file manage-
ment schemes can be used to accomplish this, the following procedure is suggested:
n Make a copy of the most recent, known−good source set. Name the copy “CONFIG01.”
n Edit “CONFIG01.” Save the set.
n Compile and Download “CONFIG01.”
n When the next change is needed, select and copy source set CONFIG01. Name the copy “CONFIG02.”
n Edit “CONFIG02.” Save. Compile and download.
n Repeat above steps as needed.
n Eventually you will want to start deleting the older sets.
By numbering the sets, there will never be any doubt about which is the latest version. Also, it will be easy to return to “known
good” sets. This suggestion is detailed in the steps below.
