Cisco PWR-2955AC Power Supply: Pros, Cons, and Conclusion

The Cisco PWR-2955AC 2.5 A, 24 V DC power supply (part number 74-3243-01) is a widely used power source for various Cisco Networking devices. Understanding the advantages and disadvantages of this power supply can help network administrators make informed decisions when considering upgrades or replacements.

Pros:

1. Versatile and Compatible: This power supply works with multiple Cisco products, including Catalyst 3850 Series Switches, Nexus 5500 Series Switches, and the Application Policy Infrastructure Controller (APIC-EM).

2. Efficient: A power factor correction (PFC) circuit reduces power loss in the power supply, keeping energy usage to a minimum.

3. Redundant and Daisy-Chain Capable: The redundant design of the power supplies in Cisco devices allows them to connect in parallel for increased reliability. This power supply can be daisy-chained, which allows multiple units to be connected through their output terminals, increasing the total available wattage.

4. Overvoltage and Overcurrent Protection: The power supply is designed to protect itself from overvoltage and overcurrent situations.

5. Modular Design: Cisco's modular design allows for easy integration and maintenance of power supplies in their networking devices.

Cons:

1. Expensive: The Cisco PWR-2955AC power supply is considered pricey compared to third-party solutions, making it a significant investment for some organizations.

2. Single Fan Design: This power supply employs a single fan, which can result in a lack of redundancy for cooling purposes. In a mission-critical environment, the failure of the fan could potentially cause the power supply to overheat.

3. Limited Output: With a maximum output of 2.5 Amps, it might not meet the power requirements of larger or more power-hungry Cisco networking devices.

Conclusion:

The Cisco PWR-2955AC power supply, part number 74-3243-01, is a versatile and reliable solution for small to medium power requirements for various Cisco networking devices. Its compatibility with multiple Cisco products, energy efficiency through power factor correction, and redundant and daisy-chain capabilities make it an attractive choice for network administrators. However, its high cost, lack of fan redundancy, and relatively low maximum output might deter smaller organizations or those with larger power requirements from considering this power supply. Ultimately, the decision to invest in the Cisco PWR-2955AC power supply is subject to a careful evaluation of the specific needs and constraints of your organization.

Recommendation:

If your organization requires a power supply that meets the power requirements and compatibility needs of Cisco networking devices and can afford the investment, the Cisco PWR-2955AC power supply is an excellent choice due to its versatility, efficiency, and redundancy features. If a lower-cost alternative that does not sacrifice critical features is needed, consider reviewing third-party power supply options that may suit the organization's needs while providing cost savings.
