7 MIC-3392MIL User Manual
Chapter 1 Hardware Configuration
1.2.17 Hardware Monitor
One Hardware Monitor (W83627HG) is available to monitor critical hardware param-
eters. It is attached to the BMC to monitor the CPU temperature and core voltage
information.
1.2.18 Super I/O
The MIC-3392MIL Super I/O device provides the following legacy PC devices:
! Serial ports COM1 and COM2 are connected to the rear I/O module.
! The parallel port is routed to the rear I/O module.
! The FDD is routed to the rear I/O module.
! The PS2 (keyboard/mouse) is routed to the rear I/O module.
1.2.19 RTC and Battery
The RTC module keeps the date and time. On the MIC-3392MILS model the RTC cir-
cuitry is connected to battery sources (CR2032M1S8-LF, 3V, 210mAH), one located
on the board and the other on the RIO-3392MIL RTM. For the MIC-3392MILC model,
the RTC circuitry can be connected to the battery source on the RIO-3392MIL only.
1.2.20 IPMI
The MIC-3392MILS model uses the Intelligent Platform Management Interface (IPMI)
to monitor the health of an entire system. A Renesas H8S/2167 microcontroller pro-
vides BMC functionality to interface between system management software and plat-
form hardware.
The MIC-3392MILS model implements fully-compliant IPMI 2.0 functionality and con-
forms to the PICMG 2.9 R1.0 specification. The IPMI firmware is based on proven
technology from Avocent. Full IPMI details are covered in Chapter 4.
The MIC-3392MILC model does not have IPMI functionality.
1.2.21 Pre-Heat on the Conduction-Cooled Model
For reliable system boot performance under extreme low temperature conditions
(e.g. -40° C), the MIC-3392MILC contains a 10W heater for warming up the PCB
components when the board temperature is below -30° C. A special firmware imple-
mented on the BMC is designed to control the heater on and off operations. Full pre-
heat details are discussed in Chapter 3.
The MIC-3392MILS does not have the pre-heat functionality.
