Software Alarm Reporting Path - Huawei U-SYS MRS6100 Technical Manual

Technical Manual
U-SYS MRS6100 Media Resource Server
Alarm reporting path of the front board of basic frame (except ALUI and
UPWR): After collecting the alarm information from the front board through
shared resource bus, the SMUI reports the alarm to the BAM through Ethernet.
Alarm reporting path of the back board: no processor exists in the back board
of MRS6100. The corresponding front board collects its status and reports it to
the SMUI board through the shared resource bus. After receiving the
information of the back board, the SMUI board sends an alarm to the BAM
through Ethernet, and delivers the back board status to the ALUI through serial
port bus. Then the ALUI drives the indicators on its front panel to indicate the
status of the back boards. A board can be in the status of uninstalled, normal
and abnormal.
Note:
The following displays the status of the boards that are configured on BAM. If a
board is not configured, its status cannot be displayed even if it is inserted.
Alarm reporting path of the power board of basic frame: The ALU collects the
status signals of the power modules through backplane and drives the
indicators on the corresponding panel to indicate the status of the power
module. Meanwhile, the ALU reports the power module status information to
the SMU through the serial port bus, and the SMU generates an alarm to the
BAM through Ethernet.
Note:
The ALUI does not provide indicators to indicate the working and in-position state of
the two front UPWRs, but provides indicators to indicate the state of the two back
UPWRs.

7.4.3 Software Alarm Reporting Path

Software alarm information includes the information of in-coordination of signaling
procedure between local office and peer office, circuit status change due to
operation on peer office, service processing failure information, CPU overload
information.
The FAM software and BAM software generate software alarm information. Alarms
generated by the FAM software modules (such as signaling processing module and
call control module.) are sent to the alarm module, which transfers them to the BAM
alarm service module. Alarms generated by the BAM are processed directly by the
BAM alarm service module.
