Patch name: LWX1.15PACH001
Location of the patch: http://support.huawei.com/support/pages/editionctrl/catalog/ShowVersionDetail.do?actionFlag=getDetail&node=000001354374&colID=ROOTWEB|CO0000000065
As explained by the R&D Department, the alarm parameters have the following meanings:
0x15: indicates equipment.
0x02: indicates an I2C component.
0x04: indicates an AND2818 chip.
The cause of the alarm is as follows: Hardware design is modified to remove an AND2818 chip, but the software is not modified accordingly and still checks the chip. As a result, the software detects abnormal communication and reports that the chip fails. This problem should be solved through a patch.
