This particular model is a Layer 2 (L2) rack-mountable switch with 48 ports, supporting 10/100/1000Base-T RJ-45 connections. One of its standout features is the Power over Ethernet+ (PoE+) capability, which enhances its flexibility in powering various network devices.

Power over Ethernet+ (PoE+)

One of the notable features of the Cisco WS-C3750X-48P-S is its Power over Ethernet+ capability. PoE+ allows the switch to deliver both data and electrical power over the Ethernet cables to connected devices. This is particularly useful for devices like IP cameras and wireless access points, eliminating the need for separate power sources and simplifying cable management.

48 Ports with 10/100/1000Base-T RJ-45

The switch comes equipped with 48 ports, each capable of handling 10/100/1000Base-T RJ-45 connections. This means it can support a wide range of devices, from computers and printers to IP cameras and VoIP phones, providing a versatile solution for diverse networking needs. The WS-C3750X-48P-S is its 48 ports, supporting 10/100/1000Base-T RJ-45 connectivity. This means it can accommodate a variety of devices, from legacy equipment with lower data transfer requirements to modern devices demanding high-speed connectivity.

Manageable Switch

The Cisco WS-C3750X-48P-S is a manageable switch, offering administrators the ability to configure and monitor the device based on the specific requirements of the network. This enhances control and allows for efficient management of network resources.

Layer 2 (L2) Functionality

As a Layer 2 switch, the WS-C3750X-48P-S operates at the data link layer of the OSI model. This means it focuses on the efficient and reliable transfer of data between connected devices within the same network. While Layer 3 switches add routing capabilities, a Layer 2 switch is often preferred in scenarios where routing is handled by dedicated devices.

Rack-Mountable and 1U Form Factor

The switch is designed to be rack-mountable, making it suitable for deployment in standard network racks. Its 1U form factor ensures that it occupies minimal vertical space, optimizing rack utilization and leaving room for additional networking equipment.

Stackable Design with 2x Expansion Slots

Scalability is a crucial aspect of network infrastructure. The Cisco WS-C3750X-48P-S addresses this by featuring a stackable design. This allows multiple switches to be interconnected, forming a unified and scalable network infrastructure. Additionally, the switch comes with 2x expansion slots, providing flexibility for future upgrades and additions to the network.

High-Performance Data Transfer

With support for Gigabit Ethernet, the Cisco WS-C3750X-48P-S ensures high-speed data transfer across the network. This is essential for applications and services that demand low latency and rapid data exchange.

Reliability through Redundancy

To enhance reliability, the switch supports redundancy features such as stack redundancy and power supply redundancy. These features contribute to the overall resilience of the network, minimizing downtime and ensuring continuous operation.

Use Cases

Enterprise Networks

The Cisco WS-C3750X-48P-S is well-suited for enterprise-level networks where a combination of high-performance data transfer and power distribution is required. Its extensive port count and PoE+ capabilities make it an ideal choice for organizations with diverse connectivity needs.

IP Surveillance

In scenarios where IP surveillance cameras are a critical component of the network, the PoE+ capability of this switch simplifies deployment. It eliminates the need for separate power sources at camera locations, streamlining and reducing overall infrastructure costs.

Voice over IP (VoIP) Deployments

For organizations relying on VoIP for communication, the Cisco WS-C3750X-48P-S ensures a reliable and efficient network. The switch's PoE+ capability ensures that VoIP phones receive both data connectivity and power over the same Ethernet cable.
