All modules use only one backplane connection, which is always the right
most backplane connector encompassed by the module’s width. This is
the slot number that determines the module’s address, (that is the sum of
the chassis number, zero based, and the slot number).

After all the modules are installed, the ReFlex Power™ system is ready
for initial operational check. It is recommended that the system be
checked prior to connecting any control and/or power to the modules.
Turn on the Power switch on the front panel of the RFPC. This will
sequentially cause the following to occur:
• The RFPC and all power modules installed will turn on their
Power indicators (green) indicating their internal power
supplies are on.
• The RFPC and all power modules will start the configuration
process. This requires about 15-30 seconds.
• The RFPC typically completes its configuration process first
but delays its communication. When it does communicate, its
Bus LED (green) lights in an irregular blinking pattern.
•
Each power module, after successfully completing the
configuration process, will also flash its Bus indicator, (green)
signaling that it is starting the internal communication process.
•
Any module that steadily illuminates, or blinks it’s Fault
indicator, (red) at the completion of this process has detected
an internal fault during the power on self-test. Troubleshooting
information is provided later in this manual.
