Note
In the Time & Date web page, if you have left any time field or date field unset and
clicked the Set Time and Date button, then the time and date default to
00:00:00 UT: 01/01/00
.
A reboot causes the preset time to pause or, in some cases, to run in reverse.
Additionally, a power cycle resets the running time and date to the default
00:00:00 UT: 01/01/00
. Thus, whenever either a reboot or a power cycle has
occurred, must reset the time and date in the Time & Date web page of any module
that is not set to receive sync.
Event Log Data Collection
The collection of event data continues through reboots and power cycles. When the buffer allowance
for event log data is reached, the system adds new data into the log and discards an identical amount of
the oldest data.
Each line that contains the expression WatchDog flags an event that was both:
• considered by the system software to have been an exception
• recorded in the preceding line.
Conversely, a Fatal Error () message flags an event that is recorded in the next line. Some exceptions
and fatal errors may be significant and require either operator action or technical support.
