Review CISCO Pwr-3845-ac/2 New Open Box Redundant Ac Power Supply For 3845

The Cisco PWR-3845-AC2 is a redundant pair of AC power supplies designed for the Cisco 3845 Integrated Services Router or Integrated Services Aggregation Services Router. These power supplies offer a high level of reliability and uninterrupted power to support mission-critical networks.

Each power supply in the PWR-3845-AC2 kit is a hot-swappable, self-contained unit that can be replaced without powering down the router. The power supplies are also reverse-compatible with earlier models of Cisco 3800 series routers, providing investment protection for existing installations.

The Cisco PWR-3845-AC2 power supplies deliver a total power output of 380 watts at 44.7V DC, and each individual supply provides 190 watts at 44.7V DC. They conform to IEEE Standard 519-1992 for Voltage Regulation and IEEE Standard 48-1994 for Power Quality and Harmonic Control.

These power supplies are designed to operate in a wide temperature range of 32 F to 104 F (0 C to 40 C) and feature a fanless design for quiet operation. They are also RoHS compliant and meet Energy Star requirements.

The PWR-3845-AC2 power supplies include a built-in power supply module (PSM) that is hot-swappable and field-replaceable. The PSM provides redundant power to the router and includes a power-sharing circuit that ensures a seamless transition between power supplies in case of a failure.

The Cisco PWR-3845-AC2 power supplies also include a number of safety features, including overvoltage, undervoltage, overcurrent, and short-circuit protection. They are also designed to meet the safety standards of various regulatory agencies, including UL, CSA, and CE.

In summary, the Cisco PWR-3845-AC2 is a redundant pair of high-performance, hot-swappable AC power supplies designed for the Cisco 3845 Integrated Services Router or Integrated Services Aggregation Services Router. These power supplies offer a high level of reliability, investment protection, and quiet operation, making them an ideal choice for mission-critical networks.

Redundant Cisco PWR-3845-AC/2 Power Supplies for Cisco 3845 Routers: Pros, Cons, and Recommendation

The Cisco PWR-3845-AC/2 is a redundant power supply unit designed for the Cisco 3845 series routers. This power supply provides uninterrupted power to the router, ensuring high availability. In this text, we will discuss the key advantages and disadvantages of using the Cisco PWR-3845-AC/2 power supplies in your Cisco 3845 router.

1. Redundancy: The primary advantage of the Cisco PWR-3845-AC/2 power supplies is their redundancy. The dual power supplies work in an active-passive configuration, with one supply providing power to the router while the other remains standby. In case of a power failure or malfunction, the standby power supply takes over, ensuring minimal downtime.

2. Enhanced Reliability: Redundant power supplies significantly increase the reliability of the router. By eliminating single points of failure, network administrators can ensure that their critical infrastructure remains up and running.

3. Improved Power Efficiency: The Cisco PWR-3845-AC/2 power supplies are more power-efficient than their single counterparts. They provide power to the router with less waste, reducing overall power consumption and costs.

4. Hot-Swappable: The power supplies are hot-swappable, meaning they can be replaced without having to power down the router or disrupt network traffic. This feature is essential for maintaining network availability and reducing the mean time to repair (MTTR).

1. Cost: The main disadvantage of the Cisco PWR-3845-AC/2 power supplies is their cost. They are more expensive than single power supplies due to their redundant design and additional features.

2. Complexity: Using redundant power supplies adds complexity to the router setup. Network administrators must ensure that both power supplies are correctly configured and functioning properly to maintain high availability.

3. Space Requirement: The Cisco PWR-3845-AC/2 power supplies require additional rack space, which may not be available in all network environments.

The Cisco PWR-3845-AC/2 power supplies offer several advantages, including redundancy, improved reliability, power efficiency, and hot-swappability. However, they also come with some disadvantages, such as increased cost, complexity, and space requirements.

If high availability is a critical requirement for your network infrastructure, the benefits of using Cisco PWR-3845-AC/2 power supplies outweigh their disadvantages. The additional cost and complexity are justified by the improved reliability and reduced downtime they provide.

If you are operating a mission-critical network or require high availability for your Cisco 3845 routers, investing in the Cisco PWR-3845-AC/2 power supplies is a recommended choice. Their redundant design, hot-swappability, and power efficiency make them an essential investment for ensuring network reliability and minimizing downtime.
