  • Page 24: Power System Monitoring

    Power System Monitoring Power System Monitoring The MultiSwitch 900-4 power system is monitored by the Management Agent Module. When changes are detected in the MultiSwitch 900-4 power system, the Management Agent Module updates the amount of power available to the network modules.

  • Page 25: Power Allocation Policy

    Management Agent Module Recalculations When a Module Is Added When you install MultiSwitch 600 modules in a MultiSwitch 900-4, the Management Agent Module automatically deducts 15 watts from the available power. Once the module’s self-test is complete, it notifies the Management Agent Module of its actual power needs.

  • Page 26: Guidelines For Calculating Power Needs

    The average input power is 428 watts maximum with the outputs loaded to 300 watts. The ratio of real power to apparent power (power factor) is 0.99. The MultiSwitch 900-4 power supply meets IEC 1000-3-2 requirements. At lower ac input voltages, the power factor may drop off, but the power supply will continue to meet requirements.
