Guidelines for Third Party Chassis
•Three are wired to the Analog Devices* Complete Thermal System Management Controller ADM1026* on the CMM. Two of them (BP_AFT1 and BP_AFT2) can only be used for temperature readings from two different thermistors (which may be located anywhere on the chassis). These provide analog input via pins 35 (AIN6) and 34 (AIN7). The third pin must be used for thermistor return (BP_AFTREF), and is grounded via pin 21 (AGND) on the ADM1026.
13.4Interfacing FRUs to the CMM
The MPCMM0002 CMM can communicate with intelligent and
Depending on the requirements, one or more IPMB buses could be configured as I2C buses for
The following
13.4.1Example Configurations
Section 13.2, “IPMB Buses” on page 63 discusses the two basic IPMB bus topologies, radial and shared, that are supported by the Chassis Management Module. Following is a list of examples which allow different combinations of these topologies. This is not an exhaustive list of possible configurations, but just a few examples. The assumption here is that there is a mix of intelligent and
Note: The following examples are only supported under firmware version 6.1 and above through appropriate configuration files.
