Features of Cisco WS-X4748-UPOE+E Line Card Switch

48 Power Over Ethernet (PoE) Ethernet Ports

The line card offers 48 ports that support Power Over Ethernet, capable of providing power and data connectivity to devices simultaneously.

Importance of Power Over Ethernet (PoE) in Networking

Power Over Ethernet plays a significant role in networking environments:

Simplicity and Efficiency

PoE enables the transmission of both power and data over a single Ethernet cable, simplifying installations and reducing clutter.

Versatile Applications

PoE technology is widely used in scenarios where powering devices remotely or in locations without power outlets is required, such as in IP cameras, VoIP phones, and wireless access points.

Benefits of Using Cisco WS-X4748-UPOE+E Line Card Switch

Data Centers

Suitable for data centers where a multitude of devices and equipment require connectivity and power through a central switching infrastructure.

Industrial Environments

Useful in industrial settings where rugged and efficient connectivity solutions are needed for powering and connecting devices in harsh environments.

High-Performance for 48 Ports Service Module

The WS-X4748-UPOE+E is a service module for the Cisco Catalyst 4500E Series switch. It provides 48 ports of Gigabit Ethernet, with each port capable of providing up to 60 watts of Power over Ethernet (PoE+), as well as an additional 8 ports of 10 Gigabit Ethernet. This service module is designed to provide high-performance switching and PoE capabilities for enterprise networks.

High-Reliability of Catalyst 4500E Series

The WS-X4748-UPOE+E Cisco Catalyst 4500E Series 48-port service module is designed to provide high reliability to the network. High reliability refers to the ability of the module to maintain network uptime and availability, even in the event of component failures or other disruptions. This is achieved through a combination of hardware and software features.

  • Hardware redundancy: The module includes hardware redundancy features such as hot-swappable power supplies and fans, allowing for the replacement of failed components without disrupting network operations.
  • Software redundancy: The module supports software redundancy features such as Cisco's Flexible NetFlow (FNF) and Virtual Switching System (VSS), allowing for the creation of virtual switch clusters that can continue to operate even if one or more physical switches fail.
  • High-availability: The module is designed to provide high availability to the network, reducing downtime and increasing network availability.
  • Redundant supervisor: The module is equipped with a redundant supervisor engine, ensuring that if one supervisor fails, the other takes over and provides continuity to the network operations.
  • Resilient network architecture: The module has been designed to work with other Cisco products that provide resilience to the network, such as Cisco's Resilient Ethernet Protocol (REP), and FlexLink which can help to detect and recover from link failures quickly.

All these features and functionalities work together to provide high reliability to the network, ensuring that the network can continue to operate effectively even in the event of component failures or other disruptions, providing business continuity, and reducing downtime.

Resiliency and High Availability

The WS-X4748-UPOE+E Cisco Catalyst 4500E Series 48 ports service module provides resiliency and high availability features to ensure that the network remains up and running in case of failure. Some of these features include:

  • Redundant Power Supplies: The service module can be configured with redundant power supplies to ensure that power is always available to the network in case of a power supply failure.
  • Hot Swappable: The service module is hot-swappable, meaning that it can be replaced without shutting down the switch, minimizing downtime.
  • Redundant Supervisor Engines: The 4500E series switch supports redundant supervisor engines, which can take over if the primary supervisor fails, ensuring that the network remains up and running.
  • Link Aggregation Control Protocol (LACP): This protocol allows multiple physical connections to be bundled together to form a single logical connection, providing redundancy and increased bandwidth.
  • Flexible NetFlow (FNF): This feature allows the administrator to monitor the network traffic and identify potential bottlenecks, allowing them to take proactive measures to prevent network downtime.
