Product Review

The Cisco WS-C3750-48PS-E switch offers a significant advantage with its 48 Ethernet 10/100 ports and 4 SFP GbE ports, catering to a wide range of networking needs and ensuring compatibility with various devices. However, its reliance on 10/100 Ethernet ports rather than offering 10/100/1000 may limit bandwidth for applications requiring higher throughput. Additionally, the switch's high-speed stacking capability of 32 Gbps and a form factor of 1RU make it an efficient choice for scalable networks, although its operational noise level of 42 to 48 dB could be a consideration in quieter environments.


The Cisco WS-C3750-48PS-E is a network switch designed to enhance workplace productivity by enabling a more efficient, reliable, and scalable network infrastructure. This switch is well-suited for medium to large scale enterprise environments, offering a mix of 48 Ethernet 10/100 ports and 4 SFP Gigabit Ethernet ports to accommodate a wide range of networking requirements. Its hardware specifications reflect its capability to manage high-density networking with efficiency and reliability. A key feature of the Cisco WS-C3750-48PS-E is its high-speed stacking bus type, which operates at 32 Gbps. This allows multiple switches to be interconnected, increasing the network's flexibility and redundancy without compromising performance. The switch is designed in a compact 1RU form factor, making it suitable for environments where space optimization is crucial. It also supports full IPv6 dynamic routing, ensuring future-proofing for evolving network demands.
  • Size: 1.73 x 17.5 x 14.8 inches, making it a compact solution for any network rack.
  • Weight: 13.2 lbs, allowing for easy installation and maintenance.
  • MTBF (Mean Time Between Failures): 166,408 hours, indicating high reliability and reduced downtime.
Operational efficiency is further highlighted by its power consumption metrics. The switch has a maximum power rating of 540 W, with a BTU output of 580 BTU/Hour. Under full throughput, it consumes 89 W, translating to a BTU output of 302 BTU/Hour. Even at a minimal 5% throughput, the power consumption is efficiently low at 84 W, with a BTU output of 285 BTU/Hour. These figures demonstrate the switch's ability to maintain energy efficiency across varying levels of network activity. Environmental adaptability is another cornerstone of the WS-C3750-48PS-E's design. It operates effectively within a temperature range of 0 °C to 45 °C and can be stored in conditions ranging from -25 °C to 70 °C. Its operational humidity range is from 10% (noncondensing) to 85% (noncondensing), ensuring reliable performance under diverse environmental conditions. The switch also maintains a noise level between 42 dB and 48 dB, minimizing acoustic disturbances in the workplace. For monitoring and troubleshooting, the switch is equipped with per-port status LEDs and system-status LEDs. These indicators provide immediate visual feedback on the operational state of individual ports and the overall system, facilitating easy management and maintenance. In terms of power input, the switch is designed to accommodate a wide range of electrical environments, supporting an input voltage of 100 to 240 VAC / 12 VDC. This flexibility ensures that the switch can be deployed globally without the need for additional power conversion equipment. In conclusion, the Cisco WS-C3750-48PS-E combines a high port count, efficient power usage, and a compact form factor with advanced networking features, making it an essential component of any modern network infrastructure. Its design considerations for environmental adaptability, energy efficiency, and operational reliability cater to the demanding requirements of enterprise-level networking, ensuring seamless connectivity and network robustness.
