1.1 Introduction
The MIC-3081 series CompactPCI is a 10U-high enclosure with eight CompactPCI slots for rack mounting, which is provided as a flexible, configurable development platform. It supports 8-slot backplane H.110 CT bus backplane and rear I/O, which is designed to speed the implementation of telecom Internet and Industrial automation applications.
Optimal for cooling airflow with hot-swap fans
A 2.5U space underneath the card slots accommodates two 163 CFM high-speed fans, to provide forced cooling air into the system. There are also two high-speed blowers on the top (1.5U space) for linear air flow to optimal the chassis cooling system. All the fans in this chassis are individually hot-swappable, allowing users to replace any of the fans without interrupting the operation of the system. The fan’s tachometer output enables the alarm module to monitor the speed of the fans. A protective circuit has been designed into the fan backplane to reduce spikes and noise during fan hot-swapping. This design allows users to replace new fans safely without turning the system off.
System fault detection and alarm notification
The MIC-3081A is integrated with a system fault-detection and alarm notification (MIC-3921). Versatile power supply options and configurations can be made according to particular application requirements. The MIC-3081B can optional with an intelligent chassis management module, the MIC-3924A, to monitor and report internal conditions via SNMP trap, email, pager and beep sounds. The system’s status including CPU (SBC) temperature, system power voltage levels, and fan speeds can be easily checked from remote web browser for administrator monitoring. The chassis management module’s serial port can be linked to a modem, to communicate to a remote host for real time monitoring, module configuration and alarm reporting. No software needed for remote monitoring since the SNMP/HTTP protocol provide an open platform for all the operating system.
Hot-swap passive backplane with H.110 CT-bus
The 6U-sized 8-slot backplane of the MIC-3081 supports 32/64-bit operation, the backplane complies with PICMG 2.1 hot-swap specification. Eight CompactPCI slots are available. Slot 8 is dedicated to the system master, while slot 1 through 7are available for 32/64-bit CompactPCI peripheral boards. Connectors P3 and P5 on each peripheral slot of the telephony backplane are configured for rear I/O, while connector P4 is configured for the ECTF H.110 CT-bus (TDM telephony bus). The
