Description
Performance and Reliability
The J8712A HP 875 Watt Power Supply for Procurve Switch 5400ZL has a power output rating of 875 watts, which is the maximum amount of power that it can provide to the switch. This is sufficient to power the switch and all of its connected devices and peripherals.
In terms of efficiency, the power supply has a typical efficiency rating of 85%. This means that for every 100 watts of power that is drawn from the power supply, 85 watts is used to power the switch and its connected devices, and the remaining 15 watts is lost as heat. This efficiency rating is relatively standard for power supplies of this size and type.
In addition, the power supply is designed to be highly reliable and durable, with built-in protection mechanisms to prevent damage from power surges and other electrical disturbances. It also includes a hot-plug support feature, which allows for the power supply to be replaced without having to power down the switch. This helps to reduce downtime and improve the overall efficiency of the switch.
Frequency Requirements
The J8712A HP 875 Watt Power Supply for Procurve Switch 5400ZL has specific input voltage and frequency requirements that must be met in order to function properly. These requirements are as follows:
- Input Voltage: The power supply requires an input voltage of 100-240 VAC, which means it can be used in a wide range of locations with different voltage standards.
- Input Frequency: The power supply requires an input frequency of 50/60 Hz, which means it can be used in locations with either 50 or 60 Hz power.
- Power Cord: The power supply comes with a power cord that can be used to connect it to an AC outlet. The cord is designed to work with the specific input voltage and frequency requirements of the power supply.
- Power Consumption: The power supply has a maximum power consumption of 875 watts.
- Input Current: The power supply requires an input current of 7.3-3.5A at 100-240VAC.
It is important to ensure that the input voltage and frequency requirements of the power supply match the voltage and frequency of the location where the switch is being used. If the input voltage and frequency are not met, the power supply may not function properly and could cause damage to the switch.
Monitoring Features
The J8712A HP 875 Watt Power Supply for Procurve Switch 5400ZL has several power management and monitoring features that help to ensure efficient and reliable power delivery to the switch. These include:
- Automatic Voltage Regulation (AVR): AVR is a feature that helps to keep the voltage supplied to the switch consistent, even if the input voltage fluctuates. This helps to prevent power loss and prolongs the life of the switch.
- Power Factor Correction (PFC): PFC is a technology that helps to improve the power factor of the supply, which in turn reduces the amount of power consumed by the switch.
- Remote Monitoring and Management: The power supply has built-in monitoring and management capabilities that allow administrators to remotely monitor the status of the power supply, including voltage and current levels, temperature, and fan speed.
- Hot-Plug Support: The power supply is designed to be hot-swappable, which means that it can be replaced without having to power down the switch. This helps to reduce downtime and improve the overall efficiency of the switch.
- Over Temperature Protection: The power supply has built-in temperature sensors that monitor the internal temperature of the power supply. If the temperature exceeds a certain threshold, the power supply will automatically shut down to prevent damage.
- Over Current Protection: The power supply has built-in over current protection that will automatically shut down the power supply if the current exceeds a certain threshold.
- Over Voltage Protection: The power supply has built-in over voltage protection that will automatically shut down the power supply if the voltage exceeds a certain threshold.
