Product Overview of Cisco WS-X4748-RJ45V+E Catalyst E-Series

The Cisco WS-X4748-RJ45V+E is a service module designed for the Catalyst E-Series switches. This module significantly enhances the capabilities of the switch by providing 48 ports with Power Over Ethernet Plus (PoE+), allowing for both data transfer and power delivery to connected devices.

Purpose of Cisco WS-X4748-RJ45V+E Service Module

The primary purpose of the Cisco WS-X4748-RJ45V+E service module is to extend the functionality of Catalyst E-Series switches, particularly in environments where Power Over Ethernet (PoE) is essential. It enables the switch to power and connect a variety of devices such as IP phones, cameras, and wireless access points.

Understanding the Technical Specifications48 Ports with Power Over Ethernet Plus (PoE+)
  • 48 Ports: The module provides 48 individual ports, allowing for the connection of 48 different devices to the switch.
  • Power Over Ethernet Plus (PoE+): This feature enables the switch to deliver both data and electrical power to connected devices, supporting the PoE+ standard for higher power requirements.
Ethernet Switch Service Module
  • Ethernet Switch: The service module essentially acts as an extension of the switch, adding more ports and PoE+ capabilities.
  • Service Module: This term refers to an additional component that enhances the services or features of the primary device, in this case, the Catalyst E-Series switch.
Importance of PoE+ in NetworkingSimplified Device Connectivity
  • PoE+ eliminates the need for separate power cables, simplifying the installation and management of devices connected to the switch.
Flexibility in Device Placement
  • With PoE+, devices like IP cameras and wireless access points can be placed in locations without easy access to power outlets, providing flexibility in deployment.
Efficient Power Management
  • PoE+ allows for centralized power management, enabling administrators to monitor and control the power supplied to connected devices.
Application in Network EnvironmentsEnterprise Networks
  • The Cisco WS-X4748-RJ45V+E is suitable for deployment in enterprise networks, where a large number of devices require both data connectivity and power.
IP Telephony Deployments
  • In IP telephony setups, this service module facilitates the connection of numerous IP phones without the need for additional power sources.
Benefits of Cisco WS-X4748-RJ45V+E Service ModuleScalability
  • The module offers scalability by providing 48 additional ports with PoE+, accommodating the growing needs of networked devices.
  • PoE+ eliminates the need for separate power infrastructure, reducing installation costs and making the network more cost-effective.
Simplified Deployment
  • The service module simplifies the deployment of devices by providing both data connectivity and power through a single Ethernet cable.
High-Performance of 48 Ports Module

In terms of connectivity, the WS-X4748-RJ45V+E has 48 Gigabit Ethernet ports, which can be used to connect a variety of devices to the network. It also supports a range of advanced features such as Quality of Service (QoS) controls, enabling it to prioritize certain types of traffic for improved performance.

Overall, the Part is a high-performance line card that is well-suited for use in enterprise and other high-bandwidth environments. It is designed to be easy to install and manage and can be configured and monitored through a web-based interface or a centralized management system.

Compatibility of Ethernet Module

The WS-X4748-RJ45V+E is also designed to be compatible with a variety of operating systems and management tools. It can be configured and managed through a web-based interface or a centralized management system, making it easy to integrate into existing network environments.

Overall, the Part is a versatile line card that is well-suited for use in enterprise and other high-bandwidth environments. It is designed to be easy to install and use and can be configured to support a wide range of applications and devices.


This Product is a Cisco line card switch module that is designed to provide high-performance, reliable switching for Cisco network equipment. This line card module is part of the Cisco E-Series Switch family, which is a family of high-performance, modular switching platforms that are designed for use in enterprise networks.

One of the key factors that contribute to the reliability of this product is its robust hardware design. The module is built with high-quality components and is designed to withstand the rigors of everyday use in a network environment. Additionally, the module supports redundancy and failover features which can help to minimize downtime in case of a failure.

It's also important to note that, while the module itself may be reliable, the overall reliability of the network also depends on other factors, such as the quality of the network design and the compatibility of the module with the other network equipment. It's important to verify the compatibility of this module with the equipment it will be used on and follow the recommended installation and configuration guidelines.

The module also supports advanced features such as Quality of Service (QoS) which allows to prioritize network traffic, Link Aggregation Control Protocol (LACP) which increases the bandwidth by combining multiple links, and Port Security feature which helps to secure the port against unauthorized access.

This module is end of sale and end of life (EoS & EoL) which means it's no longer available for purchase and Cisco no longer provides technical support or software updates for it. So, it is important to find a suitable alternative if this module is no longer supported.

In general, the WS-X4748-RJ45V+E is designed to be a reliable switching module for Cisco network equipment, but it is important to properly design, configure, and maintain the network to ensure optimal performance and reliability.
