4. Fault Diagnosis
4.1 General
If a fault occurs to the NEAX2400 IMX OAI System, the corresponding system message is displayed. This
section explains the procedures of fault diagnosis by system messages and of fault repairs.

4.2 Diagnosis from System Messages
The flow of works from diagnosis of system message up to discovery of the cause of the fault is shown in
Figure 6-3.
Figure 6-3   Flow of Diagnosis out of System Messages
Diagnosis from System Message
Identification of Faulty Card, Faulty Equipment
Check the cause of the fault by diagnosing the printed out system messages.
If, during the diagnosis, an alarm such as circuit card initialization, etc., has been indicat-
ed, reset (clear) the alarm indication by depressing ALM RST key on the frame-top alarm
panel.
If, as a result of the diagnosis, the fault is a temporary one, cancel all alarm indications
and release system messages stored in the memory by RALM command and keep
watching the system operations thereafter.

4.2.1 TCP/IP Link Failure
For details of System Massage “4-R” and “26-V”, see Section 3.2.1 and 3.2.2 in this Chapter.
According to each fault situation, perform the repairing procedure referring to Ta b l e  6 - 4 and Ta b l e  6 - 5.
When Message “4-R” is displayed:
When Message “26-V” is displayed:

ERRK Detail information of ERRK Check Item
01TCP/IP connection is down for the TCP connection 
disconnection from Host.Re-start the Host
02Incorrect text format is received. [1] Check the software operation on the 
Host side
[2] Check the LAN cable connection
0ATCP/IP connection establishment is not completed for the 
TCP connection disconnection ordered from Host.Re-start the Host
0BTCP/IP connection establishment is not completed for the 
TCP connection disconnection ordered from Host.[1] Check the TCP/IP transmission 
capacity on the UAP side is proper
or not.
[2] Check the system operation on the
UAP side.
0CAccording to Heart Beat function of Host, abnormal status of 
the Host system operation is detected.Check system operation of the Host
0D Not used
0ETCP port is released due to the detection of abnormal state in 
the TCP/IP port (such as B-level Infinite Loop, etc.).Re-check the operation status of Host.
0F~FF Not used
Table 6-5 Repairing Procedure for TCP/IP Link Failure (Message “26-V”)
ERRK Detail information of ERRK Check Item
01TCP/IP connection is down because the text is not transmit-
ted continuously.[1] Check the TCP/IP Transmission 
capacity on the UAP side is proper
or not.
[2] Check the operation status on the
UAP side is normal.
02Incorrect text format is received. [1] Check the software operation on the
Host side.
[2] Check the LAN cable connection status.
03TCP/IP connection is released due to the TCP port discon-
nection order from the Host.Re-start the Host computer.
04TCP port is released due to the detection of abnormal state 
in the Host operation.Re-check the operation status of Host.
05TCP/IP connection cannot be established due to the connec-
tion port capacity over.The number of allowed ports for application 
use via TCP/IP must be 16 or less. Adjust the 
total port number within this range.
