Introduction to the AC PSU
The PWR-850-AC-2RU is a Cisco 850 watt AC power supply that is designed to provide reliable and efficient power to Cisco routers and switches. This power supply is part of the Cisco Power Supply portfolio, which offers a wide range of power supply options to meet the needs of different Cisco devices.
The PWR-850-AC-2RU is a 2RU (Rack Unit) form factor power supply that supports both AC and DC input voltage. It is designed to operate at an input voltage of 100-240V AC and has a wide-range input voltage that allows it to be used in different regions around the world. The PWR-850-AC-2RU is also equipped with a built-in power factor correction (PFC) feature that helps to reduce power consumption and increase energy efficiency.
The PWR-850-AC-2RU is also equipped with a variety of protection features to ensure the safety of the system and the power supply. These features include over-voltage protection, over-current protection, and over-temperature protection. The PWR-850-AC-2RU also has a built-in fan that helps to keep the power supply cool, ensuring that it operates at optimal temperatures.
The PWR-850-AC-2RU is a hot-swappable power supply, which means that it can be replaced without having to power off the system. This feature increases the availability and uptime of the system.
Voltage Requirements and Input Range
The PWR-850-AC-2RU Cisco 850 watt AC power supply has a wide range of input voltage requirements and can operate within the range of 100-240V AC. The power supply is designed to support both single-phase and three-phase power, which makes it suitable for a wide range of applications and regions around the world. The power supply also has a built-in power factor correction (PFC) feature which helps to reduce power consumption and increase energy efficiency.
The input frequency range for the PWR-850-AC-2RU is 47-63Hz, which means it can accept input power supply between 47 to 63 hertz. It also supports a wide range of temperature and humidity, which means it can operate in different environmental conditions.
It is important to note that the PWR-850-AC-2RU requires a power cord and cable connections to supply power to the system, and the specific power cord and cable connections required will depend on the specific system that the PWR-850-AC-2RU is powering. It is recommended to use the power cords and cables provided by the manufacturer, to ensure that they are compatible with the PWR-850-AC-2RU and the system, and to prevent any potential damage to the device.
Troubleshooting and Maintenance
The PWR-850-AC-2RU Cisco 850 watt AC power supply is a reliable and efficient power supply, but like any electronic device, it may require troubleshooting and maintenance from time to time. Below are some common troubleshooting steps and maintenance procedures that can help to ensure optimal performance of the PWR-850-AC-2RU:
- Verify that the power supply is properly installed and connected to the system. Make sure that the power cord and cable connections are secure and that the input voltage and frequency match the specifications of the power supply.
- Check the LEDs on the power supply. The PWR-850-AC-2RU has several LEDs that indicate the status of the power supply. If the LEDs are not illuminated or are flashing, refer to the user manual for troubleshooting information.
- Check the temperature of the power supply. The PWR-850-AC-2RU is equipped with a built-in fan that helps to keep the power supply cool. If the power supply is running too hot, it may be caused by poor ventilation or a malfunctioning fan.
- Check the system logs for error messages. The PWR-850-AC-2RU is designed to generate error messages in the event of a problem. Reviewing the system logs can help to identify the problem and take appropriate action.
- Regularly check and clean the fan. Dust and dirt can accumulate in the fan, which can reduce its efficiency and cause the power supply to overheat.
- Replace the power supply if it is no longer working properly. If the power supply is not functioning properly or has reached the end of its service life, it may need to be replaced.
- Follow the recommended maintenance procedures in the user manual, such as updating the firmware and configuring the security settings.
