The MIC-3920/MIC-3921 is an intelligent PC-system monitoring module. It can detect abnormal system conditions and generate alarm outputs, allowing users to take action before system failure. With the MIC-3920/MIC-3921, the MIC-3000 series system is changed into an intelligent, self-diagnostic system, increasing the reliability of critical application, such as in communications or computer telephony.
The alarm module comes in two versions: the MIC-3920 and the MIC-3921. The MIC-3920, using front panel LEDs for status display, is a 3U high, 2-slot (8TE) wide module which can be inserted into a 3U CompactPCI chassis such as the MIC-3001/8. The MIC-3921, equipped with a high-brightness vacuum fluorescent display and a control keypad, can be inserted into the MIC-3021/8 top reserved device bay.
