Intel EPS1U Manuel D’Utilisation

  

 

STATUS 

Two pins will be allocated for the FRU information on the power supply connector.  One pin is the Serial Clock 
(SCL).  The second pin is used for Serial Data (SDA).  Both pins are bi-directional and are used to form a serial 
bus.  The FRU circuits inside the power supply must be powered off of 5 VSB output and grounded to ReturnS 
(remote sense return).  The Write Control (or Write protect) pin should be tied to ReturnS inside the power supply 
so that information can be written to the EEPROM. 

FRU data shall be stored starting in address location 8000h through 80FFh.  The FRU data format shall be 
compliant with the IPMI specifications.  The current version of these specifications is available at 
http:\\developer.intel.com/design/servers/ipmi/spec.htm.   

The information to be contained in the FRU device is shown in the following table.
