Product Review

The Cisco WS-C4948E-S switch offers 48 10/100/1000 RJ45 ports and four 10GbE SFP+ ports, catering to high-density, high-speed networking requirements. However, the lack of a power supply and no support for Cisco TwinGig or OneX Converter Modules may limit flexibility in certain network setups. It supports a high switching capacity of 176 Gbps and a throughput of 131 Mpps for IPv4, coupled with advanced features like front-to-back cooling and hot-swappable fans, making it suitable for environments demanding continuous operation and efficient cooling.


The Cisco WS-C4948E-S is a highly efficient, 1 Rack Unit (RU) switch designed to meet the rigorous demands of enterprise and data center environments. This switch offers a comprehensive set of features, making it an ideal choice for businesses looking for a scalable and reliable networking solution. At its core, the Cisco WS-C4948E-S provides 48 10/100/1000 RJ45 ports and 4 10GbE SFP+ ports, supporting high-speed connectivity and allowing for a wide range of network configurations. Despite not coming with a power supply, it incorporates front-to-back cooling, ensuring optimal performance without overheating. The device measures 1.75 x 17.5 x 19.4 inches and weighs 19 lbs, making it compact enough for efficient use of rack space without compromising on port density. The hot-swappable fan feature ensures minimal downtime, as fans can be replaced without powering down the device. Power efficiency is a key consideration in the design of the WS-C4948E-S. It has an average power consumption of 230W and can go up to a maximum of 275W under full load, balancing performance with energy use. For mounting, the switch offers flexibility with front and rear mount options, including a high-performance rear mount, accommodating various rack configurations. In terms of performance, the switch boasts a switching capacity of 176 Gbps and offers throughput of 131 Mpps for IPv4 traffic and 110 Mpps for IPv6, ensuring swift data processing and transmission. It supports up to 57,000 routes, 55,000 MAC addresses, and allows for 4094 PVST and VLAN IDs, making it suitable for large and complex network infrastructures. The Cisco WS-C4948E-S does not support the Cisco TwinGig or OneX Converter Modules, focusing instead on direct 10GbE connectivity through its SFP and SFP+ uplink ports. This approach streamlines the network infrastructure by eliminating the need for additional conversion modules. Key hardware specifications include:
  • Switching Capacity: 176 Gbps
  • Throughput: 131 Mpps (IPv4), 110 Mpps (IPv6)
  • Supported Routes: 57,000
This switch also excels in network segmentation and security, supporting 4094 Spanning Tree Protocol instances, an equal number of Switched Virtual Interfaces and active VLANs, alongside 28,000 multicast routes. For traffic analysis and security, it provides 8 ingress and 8 egress ports for the Switched Port Analyzer (SPAN), facilitating detailed network monitoring. With hardware entries capped at 32,000, the Cisco WS-C4948E-S can handle extensive device and IP address management, suitable for growing enterprises and data centers. This switch’s robust feature set, combined with its compact and efficient design, makes it a powerful tool for managing complex networks, ensuring high performance, reliability, and scalability for modern business needs.
