Product Review

The Cisco C1-WS3650-24PS/K9 excels in providing a comprehensive solution for medium to large scale networks, offering 24 PoE+ ports and 4 SFP Gigabit Ethernet uplinks for versatile connectivity options. However, it comes with only one default power supply, which might limit redundancy for critical network infrastructure. Its power efficiency is notable, with relatively low consumption across varying traffic loads, but the initial hardware investment can be significant for budget-conscious deployments.


The Cisco C1-WS3650-24PS/K9 is a versatile networking device designed to support a wide range of applications from enterprise to high-demand data environments. This model comes equipped with 24 10/100/1000 Ethernet ports that support Power over Ethernet Plus (PoE+), enhancing the ability to power IP devices directly through the network cable. It also includes 4 Gigabit Ethernet uplinks with small form-factor pluggable (SFP) slots for fiber connectivity, enabling high-speed uplink connections. This switch is engineered for efficiency, with a default AC power supply rated at 640 WAC. Power consumption varies based on traffic, with 53.8 W at 0% traffic, 65.3 W at 10% traffic, and a slight increase to 65.9 W at 100% traffic, leading to a weighted average power consumption of 64.18 W. Such efficiency is crucial for reducing operational costs in network deployments. The hardware specifications of the Cisco C1-WS3650-24PS/K9 are impressive, featuring 4 GB of DRAM and 4 GB of flash memory, providing ample space for operating systems and applications. The switch supports up to 24,000 Flexible NetFlow (FNF) entries, allowing for enhanced network traffic monitoring and analysis. Wireless bandwidth per switch can reach up to 20 Gbps, with a forwarding rate of 77.37 million packets per second (Mpps), ensuring high performance for data-intensive applications. Key hardware features include: - Stacking bandwidth of 160 Gbps, facilitating high-speed data transfer between stacked switches. - Support for up to 32,000 MAC addresses and 24,000 IPv4 routes, enabling complex network topologies and large-scale deployments. - Capability to handle up to 4,094 VLAN IDs and 1,000 switched virtual interfaces, providing extensive network segmentation options. Further enhancing its capabilities are support for jumbo frames up to 9198 bytes, facilitating efficient large data packet transfers.
