Intel© LB440GX 2U Rack Server Chassis TPS Rev 1.0 output load, nominal input voltage, with line source interruptions not to exceed one period of the AC input power frequency (i.e. 20 milliseconds at 50Hz). The power supply is not damaged by AC surge ring wave up to 3.0kV/500A. This ring wave is a 100kHz damped oscillatory wave with a specified rise-time for the linear portion of the initial halfcycle of 0.5µsec. Additionally, the chassis will not be damaged by a unidirectional surge waveform of up to 1.5kV/3000A, with a 1.2µsec rise time and 50µsec duration. Further details on these waveforms can be obtained in ANSI/IEEE STD C62.45-1992. 3.4 Power Supply Connector Pin Assignments 3.4.1 P1 Main Power Connector Housing: 24-pin Molex* 39-01-2240, Contact: Molex 39-00-0038 Pin Signal 1 +3.3VDC 2** +3.3VDC +3.3V remote sense 3** COM 3.3V remote sense RTN 4 +5VDC 5 COM 6 +5VDC 7 COM 8 PWR OK 9 5VSB 10 +12VDC 11 +12VDC 12 +3.3VDC 18 AWG Color Orange Orange Orange Black Black Red Black Red Black Gray Purple Yellow Yellow Orange Pin Signal 13 +3.3VDC 14 -12VDC 18 AWG Color Orange Blue 15 COM Black 16 PS_ON_L Green 17 COM Black 18 COM Black 19 COM Black 20 -5V White 21 +5VDC Red 22 +5VDC Red 23 +5VDC Red 24 COM Black Table 3. 20+4-pin "Modified ATX" Power Supply Connector § Note**: The 3.3V power and 3.3V remote sense are double crimped into a single contact at pin 2. The 3.3V remote sense return and COM are double crimped into a single contact at pin 3. § The "Modified ATX" main power connector is configured as the standard ATX 20 (2x10) pin connector plus a 2x2 (4) pinout designed to supply additional +5VDC to the board. For connecting this into the Intel® L440GX+ server board, use the 24-pin power connector on the board. 5
