1.1 Outline
It is recommended to replace the whole unit (50G, OPU, power box, C3S) if any problem
occurs at the customer’s site in order to reduce the downtime of the system.
It is desirable to have the bad unit brought back and repaired. (Although it depends on the kind
of the problem.)
This section explains about the information (log file) required to know what has occurred and
what to be done.
1.2 Probable problems
- System connection failure and condition setting failure during installation
- Electrical and mechanical system failure, malfunctioning, bad image, noise, and
communication error
- Software and specifications problem

Gather information when:
- Communication error related to Dr. Watson occurred between the OPU and the CXDI,
resulting in CXDI application failure

hardware and optional software)
(2) Dr. Watson log
C:\Documents and Settings\All Users\Application Data\Microsoft\Drwatson\drwts32.log
(3) Event viewer system log
C:\WINDOWS\system32\config\SysEvent.Evt
(4) The whole D:\Ccr folder
Depending on the timing the error has occurred, images may be saved in a folder before dtstore.
In this case, copy dttmp and dtque folder.
1.3.2 When Error occurs

communication module, etc.) is used or not.
