    SECTION 5 - TROUBLESHOOTING

    INTRODUCTION
    Troubleshooting the INICI01 and INICI03 INFI-NET to Computer Interfaces is limited to viewing the contents of the error counters and the module status report from any INFI 90 operator interface. Refer to the instruction for your specific computer interface for information on module status reports.

    ERROR COUNTERS
    All INFI-NET communication modules have faceplate LEDs that serve as error code displays. The NIS module has event and error counters that are selectable (refer to Tables 3-5 and 3-6).

    INNIS01 MODULE ERROR CODES


    The NIS module error counters count errors in the same manner as the event counters count events. Table 3-6 lists the error counters. The NIS module halts operation if a fatal error condition occurs. Group A LEDs display error codes. Group B LEDs are off when group A LEDs are displaying error codes. Refer to Table 5-1 for a list of error codes and associated corrective action. Table 5-1. INNIS01 Module Error Codes
    Code 13 16 31 32 33 34 35 36 37 38 3E LED 87654321 00010011 00010110 00110001 00110010 00110011 00110100 00110101 00110110 00110111 00111000 00111110 Condition ROM checksum error Loopback test failure Memory or CPU fault Address or bus error Illegal instruction Trace/privilege violation Spurious/unassigned exception Divide by zero/checksum/ format error Trap instruction Invalid dipswitch setting on NIS module NIS/device handshake failure Check dipswitch SW1 through SW4 Verify that dipshunt exists between NIS and ICT modules. If dipshunt exists, replace NIS or ICT module. Corrective Action Replace NIS module Replace NIS module, check cabling and termination unit Replace NIS module Reset ICT module, replace NIS module if error continues

    NOTE: 0 = LED OFF, 1 = LED ON.

    TROUBLESHOOTING

    INICT01 AND INICT03 MODULE ERROR CODES


    If errors occur while the ICT module is operating, the status LED turns red and the CPU LEDs on the ICT module faceplate display error codes. Table 5-2 lists the ICT module error codes and associated corrective action. The ICT module displays error codes only when it is halted. Five status bytes provide information about the ICT module status. Tables 5-3, 5-4, and 5-5 list the NIS module edge connector pin assignments. Tables 5-6, 5-7, and 5-8 list the INICT01 module edge connector pin assignments. Tables 5-9, 5-10, and 5-11 list the INICT03 module edge connector pin assignments. Tables 5-12 and 5-13 list the IMMPI01 module edge connector pin assignments. A code that is not on the list may appear if a machine fault time-out occurs. Reset the ICT module if this happens. The ICT module has failed if the status LED remains red. Replace the ICT module in this case. Table 5-2. INICT01 and INICT03 Module Error Codes
    Code 0D 12 13 19 31 32 33 34 35 36 39 3F LED 87654321 00001101 00010010 00010011 00011001 00110001 00110010 00110011 00110100 00110101 00110110 00111001 00111111 Condition I/O expander bus errors NIS module not responding ROM checksum error SCSI port error (INICT03 only) Memory or CPU fault Address or bus error Illegal instruction Trace/privilege violation Spurious/unassigned exception Divide by zero/checksum/ format error Duplicate node number on loop The ICT module has stopped because the user pressed the stop pushbutton Change node number Reset ICT module Corrective Action Check I/O expander bus for connections to other modules. Replace NIS module. Replace NIS module Replace NIS module, check cabling and termination unit Replace ICT module Reset ICT module, replace ICT module if error continues

    NOTE: 0 = LED OFF, 1 = LED ON. 1. Codes are displayed only when the ICT module is halted and the status LED is red.
