 Overview of the EMUA

About This Chapter

Applicable to all types of BTSs/NodeBs manufactured by Huawei, the outdoor environment
monitoring unit (EMUA) is used to monitor the environment in the equipment room and the
cabinet.

2.1 Functions of the EMUA

This describes the functions of the EMUA. Providing a variety of input ports for monitoring
signals, the EMUA supports real-time monitoring and remote monitoring. In addition, the
EMUA is highly reliable and can be flexibly configured. It supports a large area for temperature
monitoring.

2.2 Exterior of the EMUA

Each Module of EMUA has three types of exterior A, B, and C.

2.3 Internal Structure of the EMUA

This describes the internal structure of the EMUA.

2.4 Communication Ports on the EMUA

The EMUA provides the RS485 and RS232 ports for the communication between the EMUA
and the BTS/NodeB. Specifically, the EMUA4832 provides an independent commissioning
port.

2.5 Monitoring Ports of the EMUA

The EMUA provides monitoring ports for the humidity/temperature sensor, smoke sensor, water
sensor, infrared sensor, and door status sensor. In addition, the EMUA provides monitoring ports
for the Boolean signal sensor, analog signal sensor, and output control sensor, which are extended
sensors.

2.6 Technical Specifications of the EMUA

This describes the technical specifications of the EMUA.
