8.2 Troubleshooting
If the LEDs that indicate the status of the product show other than the normal indications
specified in Table 2-1, Status LEDs, or if an error is detected at a human interface station,
stop using the product and contact the nearest Toshiba service office concerned.
For how to read RAS data, system logs, etc., refer to the Operation Manual for the
Engineering Tool.
Note: The memory backup time of the AN712 module varies depending on the ambient
module temperature as follows:
25
o
C: 20 hours or more
Because the information may become lost if power is switched off for a long time, collect
it as soon as possible using the engineering tool.
Remember, however, that the backed up information is RAS data, system log, etc., and
does not include control data. Therefore, operation at restart will not be adversely
affected.
