Troubleshooting Faqs - Emerson PACSystems RSTi-EP Quick Start Manual

Troubleshooting FAQs

1. Why does my controller not power on after I apply power? (None of the front
panel LEDs are illuminated.)
a. The incorrect power supply may be used. Verify that
the correct power supply is connected, and that the
power connector is fully seated. Power supply
reference information is available in Section 3, Module
Start-up.
b. The polarity may be reversed. Verify the polarity of the
incoming DC power. The positive, negative, and earth
symbols are printed on the power connector of the
front panel, as indicated in Figure 17.
c. Power may be present, but the LED indicators are not
operating as designed. Plug a live Ethernet cable into
any of the ports for LAN1 or LAN2 to verify the
following:
a.
b.
d. If none of the above options work, we recommend returning the product.
2. Why does the Fault LED continuously flash after I apply power to the controller?
a. The firmware may be corrupt. Power cycle the controller to initiate the
boot loader's repair sequence.
b. If consecutive power cycles do not correct the problem, the drive partition
may be corrupt. This is an unrecoverable condition, and we recommend
returning the product.
