Reliable and Secure Network Connectivity of 4500 Series Switch

The WS-X4648-RJ45-E Cisco Catalyst 4500 Series 48 ports Switch Module provides reliable and secure network connectivity through several features and technologies.

First, the switch module uses Cisco's IOS software, which is known for its stability and security features. This software provides a wide range of security features such as access control lists (ACLs), authentication, and encryption, which can be used to protect the network from unauthorized access and data breaches.

Additionally, the switch module supports various technologies such as Quality of Service (QoS) and Link Aggregation Control Protocol (LACP), which help to ensure that network traffic is handled efficiently and effectively. QoS allows for the prioritization of important network traffic, while LACP allows for the bundling of multiple network connections to increase the available bandwidth.

The switch module also supports Cisco EnergyWise, which allows for the monitoring and management of energy consumption on the network. This can help to reduce energy costs and improve the overall efficiency of the network.

High-Density Networking Applications

The WS-X4648-RJ45-E Cisco Catalyst 4500 Series 48 ports Switch Module is a high-density networking device designed for use in large enterprise networks. It is a 48-port 10/100/1000 Ethernet switch module that can be installed in a Cisco Catalyst 4500 series chassis. The module supports both standard and power over Ethernet (PoE) connections, allowing for the efficient deployment of network devices such as IP phones, wireless access points, and security cameras.

The WS-X4648-RJ45-E is designed to support high-density networking applications such as data centers, enterprise campus networks, and service provider environments. It provides high performance and low latency, making it ideal for use in environments where large amounts of data need to be transmitted quickly and efficiently.

The module also supports advanced features such as Quality of Service (QoS), VLANs, and Link Aggregation Control Protocol (LACP) to help ensure that network traffic is properly prioritized and managed. Additionally, the WS-X4648-RJ45-E is equipped with advanced security features such as Access Control Lists (ACLs) and Port Security to help protect against unauthorized access and network threats.

Power and Energy Efficiency of Catalyst Switch

The WS-X4648-RJ45-E Cisco Catalyst 4500 Series 48 ports Switch Module is a high-performance switch module that is designed for use in large enterprise networks. This module offers several features that make it highly powerful and energy efficient.


  • The WS-X4648-RJ45-E switch module is designed to provide high-speed data transfer and high port density, which allows it to handle large amounts of network traffic with ease.
  • It supports Power over Ethernet (PoE) and PoE+ which allows the switch to power connected devices such as IP phones, cameras, and wireless access points directly through the Ethernet cable.
  • It also supports StackPower technology which allows for power sharing between multiple switch modules in a stack, providing redundancy and increasing overall power efficiency.

Energy Efficiency:

  • The WS-X4648-RJ45-E switch module supports Energy Efficient Ethernet (EEE) which reduces energy consumption during periods of low network activity.
  • It also supports Cisco EnergyWise technology which allows network administrators to monitor and control energy usage of connected devices.
  • The switch module also has several power-saving modes that can be activated when not in use, such as standby and sleep modes, which further reduces energy consumption.
