ALM-11272 Hardware Alarm

Description

The hardware alarm is classified into microcode alarm, BIOS check alarm, board voltage abnormal alarm, LM75 self-test alarm, LM80 self-test alarm, CPLD self-test alarm, and FPGA self-test alarm. Microcode alarm: This alarm is reported when the communication between the CORE and ME is abnormal or the thread of the micro engine is hung up. BIOS check alarm: This alarm is reported when the BIOS version is not existent or the check is faulty. Board voltage abnormal alarm: This alarm is reported when the voltage of the DPTU is abnormal. LM75 self-test alarm: This alarm is reported when the LM75 performs the self-test. LM80 self-test alarm: This alarm is reported when the LM80 performs the self-test. CPLD self-test alarm: This alarm is reported when the CPLD performs the self-test. FPGA self-test alarm: This alarm is reported when the FPGA performs the self-test.

Impact on the System

Microcode alarm: When the alarm occurs, the services carried on the local-level HubBTS and leaf BTS are disrupted.
BIOS check alarm: When the alarm occurs, the software might not be loaded or the services might be disrupted if the board is reset.
Board voltage abnormal alarm: When the alarm occurs, the services carried on the local-level HubBTS and leaf BTS are disrupted.
LM75, LM80, CPLD, and FPGA check alarm: When the alarm occurs, the services carried on the local-level HubBTS and leaf BTS are disrupted.

System Actions

Switch over the DPTU.

Possible Causes

The microcodes run abnormally.
The Flash of the DPTU is damaged or the BootROM in the Flash of the DPTU is changed.
The voltage of the board is abnormal.
The LM75, LM80, CPLD, and FPGA run abnormally.

Procedure

Manually reset the DPTU and check whether the alarm is cleared.
Y=> The alarm handling ends.

N => Go to step 2.
Replace the DPTU and check whether the alarm is cleared.
Y=> The alarm handling ends.

N => Please contact Huawei Customer Service Center.
