Product overview of the Cisco WS-C3650-48FQ-S

In the fast-paced world of networking, having a reliable and high-performance switch is crucial. Cisco, a global leader in networking solutions, presents the WS-C3650-48FQ-S from the Catalyst 3650 Series. This comprehensive guide will delve into the details of this exceptional switch, exploring its features, specifications, and the broader context of its application.

The WS-C3650-48FQ-S Cisco Catalyst 3650 48 Ports Manageable Switch is a powerful and versatile network switch designed for enterprise and data center environments. It offers 48 Fast Ethernet ports and 4 Gigabit Ethernet ports, providing high-speed connectivity for a wide range of devices.

  • The switch is designed to support advanced features such as stackable architecture, energy-efficient Ethernet (EEE), and Cisco StackPower. The stackable architecture allows multiple switches to be connected, creating a single, highly resilient network that can be easily managed. EEE technology reduces power consumption by automatically adjusting the power usage of the switch based on network traffic, helping to lower energy costs. Cisco StackPower allows power to be shared between multiple switches, providing redundant power supplies and ensuring that the switch remains operational even in the event of a power supply failure.

Key Specifications


This switch boasts 48 ports, providing ample connectivity for devices in your network. The ports support 10/100/1000Base-T RJ-45, ensuring compatibility with a wide range of devices requiring different Ethernet speeds.

Power Over Ethernet Plus (PoE+)

The inclusion of PoE+ capability is a notable feature. This means the switch can provide both data connectivity and power to devices like IP cameras, VoIP phones, and other PoE-enabled devices, simplifying cable management and reducing the need for additional power sources.

Small Form-Factor Pluggable (SFP) Slots

The WS-C3650-48FQ-S is equipped with Small Form-Factor pluggable (SFP) slots, allowing for flexible fiber-optic connectivity. This is especially beneficial when extending the reach of your network over longer distances or connecting to fiber-based devices.


The switch is fully manageable, providing network administrators with the tools to monitor, configure, and optimize network performance. This feature is crucial for maintaining a reliable and secure network environment.

Layer-4 Functionality

Layer-4 support enhances the switch's capabilities by allowing it to inspect and act upon data at the transport layer of the OSI model. This advanced functionality adds a layer of intelligence to the switch, optimizing data handling and network efficiency.

Form Factor

The WS-C3650-48FQ-S is designed to be rack-mountable in a standard 1U space, making it suitable for data centers and network closets. Additionally, its desktop switch capability provides versatility in deployment, allowing it to be placed on a desk or any flat surface.

Features and Benefits

High Port Density for Connectivity

With 48 ports, the WS-C3650-48FQ-S ensures that your network can accommodate a multitude of devices. This is particularly advantageous in environments where numerous wired connections are required, such as offices or data centers.

Power Over Ethernet Plus (PoE+)

The PoE+ capability simplifies the deployment of devices like security cameras and IP phones by eliminating the need for separate power sources. This not only reduces installation costs but also enhances the flexibility of device placement within the network.

SFP Slots for Fiber Connectivity

The inclusion of SFP slots allows for seamless integration of fiber-optic connections, providing higher bandwidth and longer reach compared to traditional copper connections. This is essential for extending the network over larger physical spaces or connecting to fiber-based equipment.

Manageability for Network Optimization

The WS-C3650-48FQ-S's manageability features empower network administrators to have granular control over the switch. This includes monitoring network traffic, configuring settings, and troubleshooting issues, ultimately leading to a more robust and efficient network.

Network management of the WS-C3650-48FQ-S Cisco Catalyst 3650 switch can be performed through several methods, including the Cisco IOS command-line interface (CLI), a web-based graphical user interface (GUI) using Cisco Network Assistant, and remotely through SNMP or Cisco's cloud-based management platform, Cisco DNA Center.

  • Cisco IOS CLI: The Cisco IOS CLI is a command-line interface that allows users to configure and manage the switch using a series of commands. It is a powerful tool for configuring advanced features and troubleshooting network issues.
  • Cisco Network Assistant: This is a web-based GUI that allows users to configure and manage the switch in a more user-friendly way. It provides a simplified interface for common network management tasks such as VLAN configuration, QoS, and network security.
  • SNMP: Simple Network Management Protocol (SNMP) is a standard for monitoring and managing network devices remotely. It allows users to monitor the switch's status and performance, and receive alerts when certain thresholds are reached.
  • Cisco DNA Center: Cisco DNA Center is a cloud-based management platform that provides a centralized view of the network and allows users to automate network management tasks such as provisioning and software updates.

All these options allow network administrators to configure and manage the switch effectively, including monitoring and troubleshooting network issues, configuring VLANs, Quality of Service (QoS), and network security, and managing software updates.

Layer-4 Intelligence

Layer-4 functionality adds an intelligent layer to the switch, allowing it to make informed decisions based on data at the transport layer. This enhances the switch's ability to prioritize and optimize data flow, contributing to a more responsive and efficient network.

Versatile Form Factor

The 1U rack-mountable design makes it suitable for deployment in standard data center racks, optimizing space utilization. Simultaneously, the desktop switch capability provides flexibility for deployment in various settings, catering to different network infrastructure needs.

Enterprise Networks

In large enterprises with diverse networking needs, the WS-C3650-48FQ-S shines. Its high port density, PoE+ capability, and manageability make it an ideal choice for connecting numerous devices across different departments.

Data Centers

For data centers requiring high-performance switches, the WS-C3650-48FQ-S delivers. Its rack-mountable design ensures efficient use of space, while its advanced features support the demands of data-intensive applications.

Small to Medium Businesses (SMBs)

SMBs benefit from the versatility of the WS-C3650-48FQ-S. Its manageable features make it accessible for businesses with limited IT resources, and its PoE+ capability simplifies the deployment of IP-based devices.

Power and Connectivity

Connecting the switch is simplified with its 48 RJ-45 ports and 4 SFP slots. The PoE+ capability adds convenience when connecting PoE-enabled devices, requiring only a single cable for data and power.
