Product Review

The Cisco WS-C4948E offers an impressive switching capacity of 176 Gbps and supports a high throughput of 131 Mpps for IPv4 and 110 Mpps for IPv6, making it suitable for environments with demanding data throughput needs. However, the lack of a built-in power supply and support for Cisco TwinGig and OneX Converter Modules may limit its flexibility in various network setups. Additionally, its comprehensive support for up to 4094 VLAN IDs, Spanning Tree Protocol instances, and Active VLANs, along with a robust set of security and management features, ensures scalable and secure network configurations.


The Cisco WS-C4948E is a high-performance, enterprise-class switch designed for data center and high-capacity enterprise applications. This model provides an exceptional balance of processing power and scalability to handle demanding network environments. The switch is equipped with 48 10/100/1000 RJ45 ports and 4 10GbE SFP+ ports, making it suitable for a wide range of connectivity requirements. Its compact design, occupying only 1 rack unit (RU), allows for efficient use of space in densely packed racks. Key hardware specifications include: - Front-to-back cooling airflow, ensuring optimal temperature management for sustained operations. - A hot-swappable fan mechanism, allowing for maintenance or replacement without disrupting the network. - Rack mounting options that support both front and rear mount configurations, as well as a high-performance rear mount for flexible installation. The WS-C4948E does not include a power supply, emphasizing its use in environments where redundant power solutions are already in place. Despite this, the average power consumption is noted at 230 W, with a maximum power consumption reaching up to 275 W, indicating its efficiency in power use relative to its performance output. In terms of performance, the switch boasts a switching capacity of 176 Gbps and offers throughput rates of 131 Mpps for IPv4 traffic and 110 Mpps for IPv6, showcasing its readiness for future network demands. The device supports up to 57,000 routes, 55,000 MAC addresses, and provides extensive support for VLANs with up to 4094 PVST and VLAN IDs. Similarly, it can handle the same number of Spanning Tree Protocol instances, Switched Virtual Interfaces, and active VLANs, illustrating its capability to manage large and complex network architectures. Multicast routing is also a strength of the WS-C4948E, with support for up to 28,000 routes, alongside hardware entry capabilities of up to 32,000, ensuring efficient network traffic management and security. For diagnostics and network analysis, the switch includes Switched Port Analyzer (SPAN) functionality with support for 8 ingress and 8 egress sessions, aiding in the monitoring and troubleshooting of network traffic. However, it's important to note that the Cisco TwinGig and OneX Converter Modules are not supported by the WS-C4948E, which might limit flexibility in certain network setups that require these specific converter types for connectivity expansion. Measuring 1.75 x 17.5 x 19.4 inches and weighing 19 lbs, the WS-C4948E's compact and lightweight design does not compromise its durability or performance. This switch is engineered to meet the rigorous demands of enterprise environments, offering a reliable foundation for high-speed network infrastructures. In summary, the Cisco WS-C4948E provides a powerful and versatile solution for businesses in need of high-capacity, reliable networking hardware. With its extensive feature set and high-performance capabilities, it stands as a critical component in modern data center and enterprise network deployments.
