Product Review

The Cisco C1-WS3850-48U/K9 offers 48 UPOE ports, providing ample connectivity for devices requiring up to 800W of PoE power, making it suitable for high-density deployments. However, its power consumption remains relatively constant across different traffic loads, indicating efficient energy use but potential underutilization of its power budget in low-traffic scenarios. With support for various network modules (C3850-NM-4-1G, C3850-NM-2-10G, C3850-NM-4-10G), the switch offers flexibility in network expansion but may require additional investment for those seeking to upgrade their networking capabilities.


The Cisco C1-WS3850-48U/K9 is a cutting-edge networking switch designed for enterprise-level operations, featuring a total of 48 UPOE ports that facilitate the seamless connection of a wide variety of devices, while also providing power over Ethernet. This model is equipped with two 440W DC power supplies, ensuring reliable operation and redundancy. The power over Ethernet (PoE) budget is set at 410W, accommodating multiple powered devices without the need for additional power sources. Power consumption is optimized for efficiency across different traffic loads, with the consumption at 0% traffic being 114.8W, marginally reduced to 114.7W at 10% traffic, and slightly increasing to 115.6W at full 100% traffic. This demonstrates the switch's ability to maintain consistent power usage, regardless of network load, with a weighted average power consumption of 114.8W. The unit's physical weight is 17.6 lbs, making it suitable for rack mounting in a variety of settings. Durability and reliability are key aspects of its design, as evidenced by its Mean Time Between Failures (MTBF) of 205,110 hours, indicating a long service life. The switch supports up to 24,000 IPv4 routes, 32,000 MAC addresses, and 4,000 VLAN IDs, making it capable of handling large-scale networks with diverse routing and virtual network requirements. It also supports up to 1,000 switched virtual interfaces and allows for the configuration of jumbo frames up to 9,198 bytes, enhancing data transmission efficiency for large data packets.
  • Stackwise-480 technology enables a highly scalable system that simplifies network management and enhances redundancy.
  • StackPower technology offers power sharing among stack members, reducing the total cost of ownership.
  • Compatibility with a range of network modules (C3850-NM-4-1G, C3850-NM-2-10G, C3850-NM-4-10G) allows for flexible network uplinks and expansion.
The switch supports up to 208 routed ports per stack and can manage up to 2,000 access points per switch/stack, making it highly effective for supporting wireless networks. Additionally, it can handle up to 64 WLANs per switch, facilitating extensive wireless network segmentation and security policies. The default AC power supply is rated at 1100W, with available PoE power of 800W, which can be further extended to 800W with a 1100W secondary power supply, ensuring ample power for connected devices. In summary, the Cisco C1-WS3850-48U/K9 stands out for its comprehensive feature set, including advanced power management, extensive network capacity, and scalability options, making it an ideal choice for businesses looking to deploy a reliable and efficient network infrastructure.
