Overview about this Catalyst 4500 Series

A power supply unit (PSU) is an essential component in any computer system. It is responsible for providing the necessary power to run all the components inside a computer. In networking systems, power supplies are even more crucial as they need to support multiple devices at the same time. One such example is the Catalyst 4500 series of switches from Cisco Systems. These switches require high-capacity power supplies to ensure uninterrupted operation. In this article, we will discuss the 341-0043 2800 Watt Power Supply for Catalyst 4500 in detail.

The Catalyst 4500 series is a family of high-performance, modular switches designed for enterprise-level networking. These switches offer scalable, secure, and highly available network services to support the latest applications and technologies. The Catalyst 4500 series is a popular choice for data centers, campus networks, and service provider environments due to its advanced features and reliability.

Power Supply Requirements for Catalyst 4500 Series

The Catalyst 4500 series switches require power supplies with high wattage ratings due to their advanced features and high-performance capabilities. The power supplies for Catalyst 4500 series switches come in different wattage ratings ranging from 2800 watts to 6000 watts. The 2800 watt power supply is the lowest wattage power supply that can be used with the Catalyst 4500 series switches.

Features of the 341-0043 2800 Watt Power Supply

The 341-0043 2800 Watt Power Supply is a hot-pluggable power supply unit designed specifically for use with the Catalyst 4500 series switches. It is a high-capacity power supply that can deliver up to 2800 watts of power to the switch. The power supply has several features that make it a suitable choice for use with Catalyst 4500 series switches.

High Efficiency

The 341-0043 2800 Watt Power Supply is a high-efficiency power supply that can deliver up to 90% efficiency. This means that the power supply can convert up to 90% of the input power into usable output power. The high efficiency of the power supply reduces energy consumption and heat dissipation, resulting in lower operating costs and longer lifespan.


The 341-0043 2800 Watt Power Supply supports redundancy, which means that multiple power supplies can be installed in the switch to provide backup power in case of a failure. The redundant power supplies can automatically take over in case of a failure of the primary power supply, ensuring uninterrupted operation of the switch.


The 341-0043 2800 Watt Power Supply is hot-pluggable, which means that it can be replaced while the switch is in operation. This feature allows for easy maintenance and replacement of the power supply without the need to shut down the switch.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

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.
