Huawei WD2M1UEIU OptiX Telecom System Card / Module

The Huawei WD2M1UEIU is a UEIU (Universal Environment Interface Unit), an environmental-monitoring board for Huawei BBU3900, BBU3910 and BBU5900 base band units. It collects external monitoring signals for the base station, supporting eight Boolean (dry-contact) alarm inputs and two RS485 environment-monitoring interfaces, allowing sensors and alarm devices such as door, temperature and humidity monitors to be reported back through the BBU. The UEIU occupies an interface slot in the BBU subrack and works alongside the UPEU power-and-environment board to give operators visibility of site conditions. It is an optional plug-in unit fitted where remote environmental monitoring is required. Supplied refurbished, the WD2M1UEIU is a direct-fit spare for maintaining installed Huawei distributed base stations.
