Page 73: Power Supplies (Mpws139)
All jumpers on JP2 and JP3 must be removed if the system is upgraded to a RAID configuration. Power Supplies (MPWS139) The InterServe 8400 uses three redundant 550 watt current-sharing power supplies. Each power supply has six outputs, is hot swappable, and is auto-ranging between 90 - 132 VAC and 180 - 264 VAC.
Page 74 3. The sum of the Initial Setting Tolerance and Line/Load Regulation does not exceed 3% for the +3.3 V, +5.1 V, and +5.0 V (always on) outputs, 5% for the +12.0 V output, and 10% for the negative output voltages. 4.
Page 75 Pinout Notes: 1. The AC OK signal is a TTL-compatible signal. It monotonically (without wavering) transitions to a high level to indicate that the AC input power is within 90 - 132 VAC or 180 - 264 VAC. The signal provides the 3 mA sink/source current as well as any current required for the LEDs. Provided that there is an AC input, this signal must be available to report whether or not the outputs are functional.
