C
PS Fan Status Monitor:
The value can be obtained by reading CR92 which represents ps fan status.
Bit Number
Meaning
0
If bit 0=0 then ps1 fan fail else fan ok
1
If bit 1=0 then ps2 fan fail else fan ok
PS Status/present Monitor:
The value can be obtained by reading CR92 which represents ps status.
Bit Number
Meaning
0
If bit 0=0 then ps1 fail else ps1 ok
1
If bit 1=0 then ps2 fail else ps2 ok
Note 1: Bus address Select function:
The Address is 5A.
Note 2: Temperature Measurement Function:
The value can be obtained by reading
CR14, 1LSB = 1 degree.
Note 3: Voltage Monitor Function:
The VIN value can be obtained by reading CR10-12
which repr3.3v, +5v, and +12v respectively, 1LSB = 0.0078125V
Example: (Please note that the value of 2, 6, and 11 were derived from component
values.)
If CR10 = D7, then the +3.3V voltage = 0.0078125 * D7 * 2 = 3.359V
If CR11 = 6C, then the +5V voltage = 0.0078125 * 6C * 6 = 5.06V
If CR12 = 92, then the m12V voltage = 0.0078125 * 92 * 11 = 12.5V
