Redundancy and Failover Capabilities

  • Redundant Power Supply: The PWR-C45-9000ACV Cisco 9000 Watt AC Power Supply supports redundant power supply, providing a secondary power supply that can take over in case of failure of the primary power supply.
  • Power Supply Unit (PSU) Failover: In case of failure of one PSU, the other PSU automatically takes over, ensuring continuous power supply to the system.
  • Hot-Swappable PSUs: The PSUs of the PWR-C45-9000ACV Cisco 9000 Watt AC Power Supply can be replaced without shutting down the system, allowing for minimal downtime during maintenance.
  • Power Supply Monitoring: The PWR-C45-9000ACV Cisco 9000 Watt AC Power Supply supports power supply monitoring, allowing for real-time monitoring of power supply status and early detection of potential failures.
  • Automatic Power Supply Redistribution: In case of failure of one PSU, the power is automatically redistributed to the remaining PSUs, ensuring that the system remains powered on.
  • Load Sharing: The PSUs of the PWR-C45-9000ACV Cisco 9000 Watt AC Power Supply are designed to share the load evenly, ensuring that no single PSU is overworked and reducing the likelihood of failure.
  • Power Supply Fault Detection: The PWR-C45-9000ACV Cisco 9000 Watt AC Power Supply supports power supply fault detection, allowing for early detection and resolution of power supply issues.
  • Power Supply Restart: In case of power failure, the PWR-C45-9000ACV Cisco 9000 Watt AC Power Supply automatically restarts, ensuring that the system is powered on and ready for use.

  • Energy Efficient Mode: The PWR-C45-9000ACV Cisco 9000 Watt AC Power Supply supports energy efficient mode, allowing for power savings and reducing energy costs.

Cooling and Thermal Management

  • Cooling Fans: The PWR-C45-9000ACV Cisco 9000 Watt AC Power Supply is equipped with cooling fans that help to dissipate heat generated by the power supply and keep it within safe operating temperatures.
  • Thermal Sensors: The power supply is also equipped with thermal sensors that monitor the internal temperature and trigger the cooling fans to turn on when necessary.
  • Air Flow: The power supply is designed with an optimized air flow path to ensure efficient cooling and thermal management.
  • Power Supply Temperature Monitoring: The power supply also has a built-in temperature monitoring system, which can be accessed through the Cisco IOS command line interface (CLI) to check the temperature of the power supply.
  • Power Supply Temperature Alarm: The power supply also has a built-in temperature alarm system, which can be configured to trigger an alarm or shut down the power supply in case of high temperature.
  • Hot-Swappable Power Supply: The power supply is hot-swappable, meaning that it can be replaced without having to power off the device or network.
  • Power Supply Redundancy: The power supply supports power supply redundancy, which provides an additional level of protection against power supply failure.
  • Power Supply Load Balancing: The power supply also supports power supply load balancing, which distributes the load evenly among all the power supplies to ensure optimal performance and thermal management.

Input Voltage and Power Connections

The PWR-C45-9000ACV Cisco 9000 Watt AC Power Supply is designed to operate with an input voltage range of 200-240VAC and a frequency of 50/60Hz.

The power supply has a total of four power connections, two for input and two for output. The input connections are made through two IEC-320-C20 connectors, and the output connections are made through two IEC-320-C14 connectors. The input connections are used to connect the power supply to an AC power source, and the output connections are used to connect the power supply to the device it is powering.

It is important to note that the PWR-C45-9000ACV is designed to be used with specific Cisco devices and is not compatible with all Cisco devices. It is recommended to check the compatibility of the device you want to use it with before purchasing the power supply.

Switching power supplies are not new inventions, first used in the 1970s. Today, they form the bulk of power supplies in the market for industrial and consumer use. As technology advances, the need for more efficient power supplies increases. The formerly famous linear power supplies cannot keep up with the new requirements, leading to the rise of switch-mode power supplies.

Efficient Thermal Management System

Power supplies generate a lot of heat in the conversion process. Not all the input AC power is converted to output DC power. The rest is lost in the form of heat, which increases the temperature inside a power supply. The switching power supplies have better thermal management, which prevents excess heating. So, they can perform well in many industrial applications.

High Efficiency

One of the reasons leading to the rise of switch mode power supply is the high efficiency. Apart from having an efficient thermal management system, the power conversion frequency is above 90%. With this high rate, you don't have to worry about power wastage even if the SMPs remain in constant operation. The saved power may not be significant for home applications, but industrial users can feel the relief on their utility bills.

Low-Cost and Long Service Life

Most of the electronic components in power supplies degrade at high temperatures. A switching power supply maintains optimal thermal conditions even if used continuously. This reduces the operating cost and lengthens the lifespan of the entire power supply unit. We can also say that you get a more reliable power supply that is not prone to hardware failure.

Low Weight and Ultimate Protection

The use of switching elements in a switch mode power supply reduces the weight of the entire unit. The size of the required transformer is also reduced. This property is ideal if manufacturing or shopping for a power supply for your portable device. These power supplies also show excellent protection properties. The protection circuitry offers short-circuit, overload, overvoltage, overcurrent, and overheating protection. They are safe for use under any conditions.

Power Factor Correction Mechanism

The ability of a switching power supply to correct power factor is on another level. The harmonics your equipment feeds back to a power system can see the authorities increasing your utility bills. Using switching power supplies takes you off the hook as the PF will always be within the permitted value.

What to Know When Shopping for a New Power Supply?

Busying a switch-mode power supply presents a challenge to many people. That is probably because of the many models and form factors available in the market today. To get it right, understand the power requirement of your system and the form factor of the power supply that will fit in the casing. You should not have any problems if you consider the power factor model.

What is the Manufacturer/Brand Warranty?

In general, a manufacturer's warranty service/support is a written guarantee to the buyer of a product. Its terms assure the replacement or repair of the product, if necessary, within a specified period after the purchase (2-5 years depending on the brand/manufacturer). It is typically included in the price of the product. Products are brand new and sealed and the original manufacturer box is complete with the Manufacturer's genuine warranty. For most of the brand new/retail products that come with the manual and box, exceptions may apply (i.e., Cisco, Juniper Networks).
