Power Supply Specifications

Input Voltages

The 300 watt power supply, designed to minimize EMI, provides sufficient power for a maximum configuration of the server. The input voltage ranges are:

￿￿100-120 V at 50/60 Hz; 4.6 A maximum current

200-240 V￿at 50/60 Hz; 2.3 A maximum current

If a system is integrated to a fully configured condition, checking the input current rating will provide an indication of whether the system is overloaded or not. The input current rating should not exceed 4.6 amperes (for 100-120Vac) or 2.3 amperes (for 200-240Vac).

Output Voltages

The table below lists the total watts available for each voltage. Adjust your loads so that the combined total wattage for your system configuration is less than 300 watts. For information about calculating the power usage for your system configuration, see page 59.

CAUTION

Do not exceed a combined power output of 167 watts for the +5 V and +3.3 V outputs. Exceeding a combined 167 watts will overload the power supply and may cause the power supply to overheat and malfunction.

The ISA slot(s) on the system board are rated at a maximum of 4.5 amperes per slot. The ISA specification recommends supporting an average of 2.0 amperes per slot. The average current usage should not exceed 3.0 amperes per slot; that is, 15 watts.

The PCI slots on the system board are rated at a maximum of 5 amperes per slot. The maximum power allowed for each slot is 20 watts at +5 volts. The average current usage per slot should not exceed 3.0 amperes per slot; that is, 15 watts.
