Product Overview

The WS-X4748-RJ45V+E is a line card for the Cisco Catalyst 4500 E-Series switches. It is a 48-port Ethernet module that supports Power over Ethernet Plus (PoE+), allowing it to provide power to devices such as IP phones, wireless access points, and other networked devices.

In terms of connectivity, the Part 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.

The Cisco WS-X4748-RJ45V+E is a service module designed for use with Catalyst E-Series switches. Specifically, this module provides 48 ports of Power Over Ethernet Plus (PoE+), making it a robust solution for delivering power and data connectivity to various network devices.

Purpose of Cisco Catalyst E-Series Switch Module

The Cisco Catalyst E-Series Switch Module serves as an expansion module for Catalyst switches. It enhances the capabilities of the switch by providing additional ports and functionalities, in this case, supporting Power Over Ethernet Plus for efficient power delivery to connected devices.

Understanding the Technical Specifications48 Ports Power Over Ethernet Plus (PoE+)
  • 48 Ports: The module features 48 individual ports, offering connectivity for a multitude of devices within a network.
  • Power Over Ethernet Plus (PoE+): This feature enables the module to provide both power and data connectivity to compatible devices, such as IP phones, cameras, and wireless access points.
Ethernet Switch Service Module
  • Ethernet Switch: The module operates as an Ethernet switch, facilitating the connection and communication between devices within a network.
  • Service Module: This designation emphasizes its role as an additional module providing specific services, in this case, PoE+ functionality.
Importance of PoE+ in NetworkingSimultaneous Power and Data
  • PoE+ simplifies network installations by allowing devices to receive power and data through a single Ethernet cable, eliminating the need for separate power sources.
Versatile Connectivity
  • Devices such as IP cameras, VoIP phones, and wireless access points can be conveniently powered and connected using PoE+, providing versatility and flexibility in network design.
Reduced Cable Clutter
  • The consolidation of power and data over a single cable reduces cable clutter, enhances cable management, and contributes to a cleaner and more organized networking environment.
Application in Network EnvironmentsEnterprise Networks
  • The Cisco WS-X4748-RJ45V+E module is suitable for deployment in enterprise networks, where a large number of devices need reliable and efficient power and data connectivity.
IP Telephony
  • Its PoE+ capabilities make it an ideal choice for supporting IP telephony systems, ensuring that IP phones receive both power and network connectivity from the same module.
Benefits of Cisco WS-X4748-RJ45V+E Catalyst E-Series Switch ModuleComprehensive Connectivity
  • With 48 ports, the module offers extensive connectivity options, allowing multiple devices to be connected simultaneously.
PoE+ Functionality
  • The inclusion of PoE+ functionality provides the ability to power devices over the network, simplifying installation and reducing the need for additional power sources.
  • The module enhances the scalability of the network by providing additional ports and PoE+ capabilities, accommodating the growing demands of connected devices.
Compatibility of Ethernet Module

The WS-X4748-RJ45V+E is a line card that is compatible with the Cisco Catalyst 4500 E-Series switches. It is designed to be inserted into the switch chassis, where it can be used to expand the number of available ports and add additional functionality to the switch.

In terms of device compatibility, the Part has 48 Gigabit Ethernet ports, which can be used to connect a wide range of devices to the network. These can include computers, servers, IP phones, wireless access points, and other networked devices.

Resiliency and High Availability

The WS-X4748-RJ45V+E Cisco line card switch module is designed to provide high resiliency and high availability in enterprise networks.

One of the key features that contribute to the resiliency and high availability of this product is its support for redundant power supplies and redundant cooling. This means that the module can continue to operate even if one of the power supplies or cooling fans fails, which helps to minimize downtime.

The module also supports advanced features such as Cisco FlexStack, which allows you to stack multiple switches together to form a single logical switch, increasing the system's resiliency. This feature helps to minimize downtime by providing redundancy and failover capabilities.

Additionally, the module supports features like Link Aggregation Control Protocol (LACP) which increases the bandwidth by combining multiple links and improves the network resiliency by providing redundancy. Also, the Port Security feature helps to secure the port against unauthorized access and protect the network from malicious attacks.

The module also supports advanced QoS features which help to prioritize network traffic and provide high availability for critical network services such as VoIP and video.

It's important to note that, even though the module has these advanced features, it is only effective if they are properly configured and maintained. It's important to have a good network design that includes redundancy, backup, and failover mechanisms. And also to keep the software updated to ensure the highest level of resiliency and availability of the network.

It's also important to note that, as I mentioned before, 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
