13.2 BBRAM LEDs
The BBRAM (Battery Backed RAM) LEDs inform you about the condition of the
BBRAM hardware used for data storage. The following table lists the possible
situations that might occur during normal operation.
OK (Green) ERR (Red) Description
ON ON The module is in a Cold Start condition that typically occurs when you
power up the module for the first time. After at least one meter is enabled
and the processor is in RUN mode the module starts operating.
ON OFF Normal Operation
Blinking OFF This condition is warning that a checksum flag was raised after a power
cycle. If this alarm issue occurs, refer to the AFC Manager (On-line
Monitor / Checksum Alarms) in order to determine the data section in
which the alarm issue has occurred. After verifying that the checksum
error has not affected the referred memory area you may clear the
checksum alarm using the same AFC Manager interface.
After the alarm is cleared the OK LED will be ON
