Product Review

The Cisco CRS-4-AC-SUPPLY= offers a compact design for its AC power shelf, with dimensions that allow for efficient use of rack space in data centers. However, the total weight of 25 lb. (11.3 kg) when fully equipped with all AC rectifiers might pose challenges for single-person installations or adjustments. Each AC rectifier's dimensions ensure compatibility with the power shelf, but the individual weight of 4.6 lb. (2.0 kg) requires careful handling during maintenance or upgrades.


The Cisco CRS-4-AC-SUPPLY= is designed to meet the power requirements of networks demanding high availability and scalability. This AC power shelf is an essential component for ensuring the continuous operation of Cisco Carrier Routing System (CRS) platforms. It supports the integration of AC rectifiers, facilitating the conversion of AC power to DC power, crucial for the operation of network hardware. Measuring 1.7 inches (4.3 cm) in height, 16.8 inches (42.6 cm) in width, and 16.2 inches (41.2 cm) in depth, the AC power shelf is designed to fit seamlessly into standard networking racks. Its compact size ensures efficient use of space without compromising on power capacity. The unit's total weight of 25 pounds (11.3 kg) with all AC rectifiers installed, denotes a solid build quality while still allowing for manageable installation and maintenance processes. Each AC rectifier, a critical component for the power conversion process, measures 1.6 inches (4.0 cm) in height, 4 inches (10.1 cm) in width, and 13.8 inches (35.1 cm) in depth. This compact size allows multiple rectifiers to be housed within the AC power shelf, optimizing space and enhancing power supply redundancy. Each rectifier weighs 4.6 pounds (2.0 kg), balancing durability with ease of handling during installation or replacement. Key features include: -
  • Compatibility with Cisco Carrier Routing System platforms, ensuring reliable power supply for high-performance networking operations.
  • Optimized space utilization, thanks to the compact dimensions of both the power shelf and AC rectifiers, facilitating efficient use of rack space.
  • Enhanced power supply redundancy through the accommodation of multiple AC rectifiers, minimizing the risk of power interruptions to critical network infrastructure.
The Cisco CRS-4-AC-SUPPLY= is engineered to support the rigorous demands of modern data centers and network operations centers. Its design focuses on reliability and scalability, with the ability to accommodate additional AC rectifiers as network power requirements increase. The power shelf and rectifiers are constructed with attention to detail, ensuring they meet Cisco's high standards for quality and performance. In summary, the Cisco CRS-4-AC-SUPPLY= provides a reliable and scalable AC power supply solution for Cisco Carrier Routing System platforms. Its compact, efficient design allows for effective space utilization in crowded data centers, while the capacity for additional AC rectifiers supports future growth. This power shelf is an indispensable component for networks requiring uninterrupted operation and high performance.
