C Notes
1. Bus Address Select function:
The address is 5A.
2. Temperature Measurement function:
The value can be obtained by reading CR14, 1LSB = 1 degree.
3. Voltage Monitor function:
The VIN value can be obtained by reading CR10, CR11, and CR12 which rep-
r3.3V, +5V and +12V bus inputs respectively, 1LSB = 0.008V.
Example :
(Please note that the constant values of 2 , 6 and 11 in the following examples
were derived from component values.)
If CR10= D1 then the +3.3V voltage = 0.008 * D1*
2 = 3.34V
If CR11= 68 then the +5V voltage = 0.008 * 68 * 6 = 4.99V
If CR12= 89 then the m12V voltage = 0.008 * 89 * 11 = 12.05V
4. PG Status Monitor
The value can be obtained by reading CR92 which represents PG status:
If bit 2=1 then PG1 ok else PG1 fail.
If bit 3=1 then PG2 ok else PG2 fail.

C Commands
Example: PG Status Monitor
$ ipmitool -H <your-ip-address> -UADMIN -PADMIN \
i2c bus=3 chan=0 0x5a 1 0x92
0c
0c = 00001100. Bits 2 and 3 are 1, so both power supplies are operating.
Where:
<your-ip-address> is the IP address of the BMC.
-UADMIN is the user name of the administrative user of the BMC.
-PADMIN is the password of the administrative user of the BMC.
