Product information

Description

The Cisco CBS250-48PP-4G is a high-performance managed L2/L3 switch designed to provide reliable and secure network connectivity for small to medium-sized business environments. This device features 48 Gigabit Ethernet ports equipped with Power over Ethernet Plus (PoE+) capabilities, allowing for the seamless powering of network devices such as IP phones, cameras, and wireless access points. With 4 dedicated SFP uplink ports, it ensures high-speed fiber connectivity for backbone links, making it a versatile solution for modern office infrastructures.

Advantages

This switch offers a sophisticated balance between enterprise-grade performance and cost-effectiveness. By providing advanced management features like VLANs, Quality of Service (QoS), and Layer 3 static routing, it allows administrators to optimize traffic flow and ensure critical applications receive the necessary bandwidth. The inclusion of PoE+ support simplifies installation by eliminating the need for separate power sources for connected devices, while the intuitive web-based interface ensures that configuration and monitoring remain accessible even for teams without extensive networking expertise.

Suitable for

  • Powering IP surveillance cameras and VoIP phones via PoE+
  • Connecting multiple workstations in a small to medium-sized office
  • Creating segmented networks using VLANs for improved security
  • High-speed uplink connections to core network switches via fiber

This switch may not be suitable for large-scale enterprise data centers that require high-density 10GbE or 40GbE throughput, as it is primarily optimized for Gigabit connectivity. Additionally, it may be overkill for simple home networks that do not require advanced traffic management or PoE capabilities.

Key specifications

  • 48 Gigabit Ethernet ports with PoE+ support
  • 4 SFP uplink ports for fiber connectivity
  • Managed L2/L3 functionality
  • 195W total PoE power budget
  • 8000 MAC address table entries
  • Supports VLANs, QoS, and static routing
  • Rack-mountable design

To use the Cisco CBS250-48PP-4G, mount the device in a standard 19-inch server rack to ensure proper airflow and physical security. Connect your network devices to the RJ-45 ports using Ethernet cables, and utilize the SFP ports for high-speed uplinks. Once powered on, access the switch via its web-based management interface using a standard browser to configure IP settings, VLANs, and security policies. The system allows for granular control over port power allocation and traffic prioritization to suit specific business needs.

What to consider before purchase

  • Verify that the 195W PoE budget is sufficient for all your powered devices
  • Ensure your rack space supports the physical dimensions of the unit
  • Check if your existing fiber modules are compatible with the SFP ports
  • Assess whether your network requires L3 static routing features
Usage recommendations: Regularly update the firmware to the latest version provided by the manufacturer to ensure optimal security and performance. Monitor the PoE power consumption through the dashboard to prevent overloading the power budget.
