INIIT02 ERROR CODES
If module errors occur while the INIIT02 INFI-NET to INFI-NET
Transfer Module is operating, the module halts, the status LED
turns red, and the eight CPU LEDs display an error code. Table
lists the INIIT02 error codes, their meaning and corrective
action. Nonfatal module errors appear in the module status
report from the operator interface (i.e., operator interface sta-
tion, engineering work station etc.).
