If the optional server signal connector is not used on the power supply the 3. 3VRS and ReturnS lines shall be crimped into the contacts in the baseboard power connector. If the server signal connector is unplugged, the power supply shall not shutdown or go into an over voltage condition.

The wire harness ground pins shall be connected to safety ground (power supply enclosure). 6. 3 Remote Sense STATUS Optional The power assembly may have remote sense for the +3. 3V (3. 3VS) and return (ReturnS) if the Optional Server Signal connector is implemented and the module has a +3. 3V output. The remote sense return (ReturnS) is used to regulate out ground drops for all output voltages. The +3. 3V remote sense (3. 3VS) is used to regulate out drops in the system for the +3. 3 V output. The remote sense input impedance to the power sub-assembly must be greater than 200 ohms on 3. 3 VS and ReturnS. This is the value of the resistor connecting the remote sense to the output voltage internal to the power assembly. Remote sense must be able to regulate out a minimum of 200 mV drop on the +3. 3 V output. The remote sense return (ReturnS) must be able to regulate out a minimum of 200 mV drop in the power ground return. The current in any remote sense line shall be less than 5 mA to prevent voltage sensing errors. The power supply must operate within specification over the full range of voltage drops from the power assembly's output connector to the remote sense points. - 15 - SSI ERP2U Power Supply Design Guide, V1. 0 6. 4 Output Power/Currents STATUS Recommended The following tables define the power and current ratings for two recommend power levels. Depending upon the system design, the power supply modules may have only three outputs (+12V, -12V, and 5VSB) or the full five outputs (+3. 3V, +5V, +12V, -12V, and 5VSB). If only three outputs are provided from the module, the cage shall have additional DC/DC converters to generate +5V and +3. 3V from the +12V provided by the modules. The combined output power of all outputs from the cage shall not exceed the rated output power. The power assembly shall meet both static and dynamic voltage regulation requirements over the full load ranges. The power sub-assembly shall supply redundant power over the full load ranges.

Maximum continuous combined load on +3. 3 VDC and +5 VDC outputs shall not exceed 115 W. [. . . ] 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. 8. 3. 2 Module FRU Data 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 are available at: http:\\developer. intel. com/design/servers/ipmi/spec. htm. 8. 3. 3 Module FRU Data Format The information to be contained in the FRU device is shown in the following table.
