There are totally 14 DIP switches on the DCSU. The settings of the DIP switches are described as follows:
The SW11 is used for terminal matching selection. The setting of the SW11 is as follows:
In a single cabinet, SW11 is set to all ON.
In combined cabinets, all SW11s of the cabinets are set to all ON.
In the case of two combined groups, all SW11s of the cabinets are set to all ON.
In the case of three combined groups, the SW11 of the main cabinet in the main cabinet group is set to all OFF, and the SW11s of all the other cabinets are set to all ON.
The SW1 is used for determining the main cabinet in the main cabinet group. The setting of the SW1 is as follows:
All ON indicates that the selected cabinet is the main cabinet in the main cabinet group.
All OFF indicates other circumstances.

N => The alarm is not cleared. Go to procedure 3.
Check whether the rack type configured on the BSC is consistent with the actual rack type
Y => Consistent. Contact Huawei Customer Service Center.
N => Inconsistent. Go to procedure 4.
Reconfigure the rack type in the data configuration on the BSC side. Ensure that the configured rack type is consistent with the actual rack type. Check whether the alarm is cleared.
Y => The alarm is cleared. The alarm handling is complete.
N => The alarm is not cleared. Contact Huawei Customer Service Center.
