Power-Up - GE RX3i PROFINET User Manual

Chapter 5. Operations

Power-up

5.1
When power is applied to the PNS module, it loads a firmware image. During the power-up process, the
module runs diagnostics and initializes its hardware components.
After completing power-up sequence, the OK LED changes from being off to solid on green. If a fatal error
occurs during power-up, the amber OK LED blinks a unique pattern indicating the nature of the failure.
If the module encounters a hardware failure, invalid firmware image, or the power-up diagnostics fail, the
module will not become operational or may enter firmware update mode. Cycling power to the module
may restore operation. Refer to Section 6.3, Fatal Error Handling for more details.
Non-volatile settings such as the PROFINET Device Name, Ethernet network configuration, and Ethernet
Port disable settings are activated before a PROFINET connection is allowed.
