Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05
© SAMSUNG Electronics Co., Ltd. 3-17
The UCM maintains and controls the temperature inside the outdoor SPI-2210, collects and
reports the external environment alarms. The UCM detects the temperature inside the
cabinet by the sensors of the exit of the DMB and the entrance of the RFB, and operates
and controls the fan, the heater and the damper according to this, and if the alarm is
generated, the UCM reports this to the upper part via the MEI. In addition, the UCM
collects the data on the environment in real time by being connected to the environment
monitoring sensor installed inside the cabinet, and if the environmental alarm is generated,
the UCM reports this to the upper part via the MEI.
The UCM also performs the function of monitoring the environment of the rectifier cabinet
according to the RS-485 method.
The UCM turns on the lamp installed in the cabinet when the cabinet door is open by being
connected to the sensor which detects the opening/closed status of the cabinet door.
If the outdoor SPI-2210 is initialized, the rectifier supplies the power only to the UCM and
the DACS, first, to measure the temperature inside the system. If the temperature inside the
system is less or more than the permissible level, the UCM raises or decreases the
temperature by controlling the HDM (HDM-R/D) and fan (FAN-POD/FAN-POR). If the
temperature inside the system becomes normal, the UCM controls the rectifier to supply
the power to other blocks other than the UCM.
