We have the H8QMi-2 motherboard with CSE-828TQ-R1200LPB chassis. I have been tasked with chassis management and health monitoring. I know the PWS-1K22-1R power supply used in this chassis has an I2C/SMBus interface, but I have not been able to obtain any of this information, ether from the built-in sensor modules (lm_sensors on Linux 2.6.20), from probing the I2C bus, or from the IPMI interface (I have an AOC-SIMLP card installed). Can you provide any additional documentation or monitoring software to provide access to power supply status?
Use IPMI spec Master Write Cmd:
NetFn: 0x06
Cmd : 0x52
Data : 0x05 //bus 2 or 0x07 //bus 3
0x70 // slave address of PS (it can be 0x70, 0x72, 0x74 for 3 redundant PS)
0x01 // read 1 byte
0xYY // where YY is offset of the PS
(Note: For H8, X7 or earlier motherboards, the I2C bus number is 2. For X8 motherboards, the I2C bus number is 3.)
For PMBus, please use this:
NetFn: 0x06
Cmd : 0x52
Data : 0x05 // bus 2 or 0x07 // bus 3
0x78 // slave address of PS (it can be 0x78, 0x7a, 0x7c for 3 redundant PS)
0x01 // read 1 byte
0xYY // where YY is offset of the PS
