Eok Led Blink Codes For Hardware Failures (Rack-Based And Rx7I Embedded Interfaces) - GE RX3i User Manual

On the RX7i interfaces, the Ethernet LEDs are labeled EOK, LAN, and STAT.
On the RX3i rack-based Ethernet interfaces, the Ethernet LEDs are labeled ETHERNET OK, LAN OK, and LOG
EMPTY, respectively.
12.4 EOK LED Blink Codes for Hardware Failures (Rack-based and
RX7i Embedded Interfaces)
The EOK LED indicates whether the module is able to perform normal operation. This LED is on for normal
operation and flashing for all other operations. If a hardware or unrecoverable runtime failure occurs, the EOK
LED blinks a two-digit error code. The EOK LED first blinks to indicate the most significant error digit, then after
a brief pause blinks again to indicate the least significant error digit. After a long pause the error code display
repeats
