Alarm Unit board for Huawei SoftX3000/MSOFTX3000 softswitch and HLR9820 core network platforms.

The Huawei SF31WALU0 is a WALU (Alarm Unit) board, part number 03050151, used in Huawei’s SoftX3000/MSOFTX3000 NGN softswitch and HLR9820 core network platforms. The alarm unit collects and reports hardware and environmental alarms from within the equipment frame, feeding status information to the system’s operation and maintenance subsystem so faults can be identified and escalated. It is part of the same SF31 board family as the WHSC and WSIU units used on the same platforms. Tech-Star (UK-based, shipped worldwide) supplies tested Huawei core network spares; enquire to confirm exact frame/slot compatibility for your deployment.
