About the Cisco WS-C3750V2-48PS-S 48-Port PoE Switch
The Cisco WS-C3750V2-48PS-S is a member of the Cisco Catalyst 3750 Series, representing a robust, stackable, layer 3 managed Ethernet switch designed for the access layer of enterprise networks. This specific model provides 48 10/100/1000 Mbps Ethernet ports, each capable of delivering Power over Ethernet (PoE) to connected devices, alongside four Small Form-Factor Pluggable (SFP) uplink ports for fiber or copper gigabit connections to the network core. It is engineered to deliver reliable, high-density connectivity and intelligent network services for demanding environments such as corporate offices, campus buildings, and schools, where a mix of data, voice, and wireless access points must be powered and managed efficiently from a central point.
A key feature of this switch is its stacking technology, which allows multiple physical switches to be interconnected and managed as a single logical unit, simplifying configuration, redundancy, and scalability. As a fully managed layer 3 switch, it supports advanced routing protocols, Quality of Service (QoS) for prioritizing traffic like voice and video, robust security features including Access Control Lists (ACLs) and network authentication, and comprehensive management through Cisco IOS software. The integrated PoE capability on all 48 copper ports simplifies infrastructure deployment by allowing it to deliver both data and electrical power to devices such as IP phones, wireless access points, and security cameras, eliminating the need for separate power supplies and outlets near each device.
Housed in a standard 1U rack-mountable form factor, the switch is built for continuous operation with redundant, load-sharing power supplies and fans for increased reliability. Its design emphasizes operational efficiency and control, providing network administrators with deep visibility and management over connected devices, traffic flow, and power allocation. The Cisco Catalyst 3750V2 series, with models like the 48PS-S, has been a cornerstone of enterprise networking, offering a balance of performance, PoE budgeting, and advanced feature sets to build secure, resilient, and scalable wired network foundations.
