The module supplies regulated 5.1 VDC power lines across the chassis backplane bus, sustaining the voltage stability needed to maintain high-speed backplane bus communication velocity during intensive CPU sweep intervals. Active power factor correction circuits minimize harmonic distortion across the input lines. Internal logic monitors the power rails, signaling early status alerts to the host controller prior to the expiration of the 21 ms ride-through window, enabling safe processor state preservation and firmware flash compatibility interlocks.
Q: How does the overvoltage and overcurrent protection behave during a field fault?
A: The module utilizes non-destructive electronic clamping circuits. If the 5.1 VDC rail climbs to 6.2 V, the overvoltage loop clamps the output. Under overcurrent states approaching 12 A, the output voltage drops automatically. Both mechanisms protect the internal power supply fuse from opening, recovering to nominal values immediately after the field load anomaly is removed.
Q: Can this power supply module drive multiple racks simultaneously?
A: Yes. It can drive a secondary expansion rack through specialized extension cables (IC697CBL700 / IC697CBL713) provided that the auxiliary chassis requires only 5 VDC logic power and the combined current demands of both racks remain within the 56 W maximum output thresholds.
