Details Information for 48 Port Switch

The WS-X4548-GB-RJ45V is a switch module for the Cisco Catalyst 4500 series of switches. It provides 48 Gigabit Ethernet ports in a compact form factor that can be installed in the chassis of a Cisco Catalyst 4500 switch. Each port on the part supports 10/100/1000Mbps operation and auto-negotiates the speed, duplex, and flow control. All ports are also capable of providing both power-over-Ethernet (PoE) and non-PoE capabilities. Additionally, this switch module provides support for VLAN tagging (IEEE 802.1Q) and Quality of Service (QoS) features.

This model is designed to provide a high-performance and scalable switching solution for data center, enterprise, and campus networks, as it enables to expand your network while allowing more devices to connect to your network without compromising on performance.

It also has feature such as:

  • Support for industry-standard Link Aggregation Control Protocol (LACP) for bundle up to 8 ports for increased bandwidth.
  • Support for Jumbo Frame which allows for sending larger packets (up to 9216 bytes)
  • Support for Cisco EnergyWise technology which allows to monitor, measure and manage energy consumption.

It is important to note that to use this module, you need a catalyst 4500E or 4500X as the host chassis.

High Performance of Catalyst Switch

The WS-X4548-GB-RJ45V Cisco Catalyst 4500 switch module is designed to provide high-performance, reliable, and secure network connectivity for a variety of environments.

Some of its key performance characteristics include:

  • 48 Gigabit Ethernet ports with RJ-45 connectors, allowing for high-speed connectivity to other devices and networks.
  • Line-rate module, capable of forwarding all packets at wire-speed without any packet loss.
  • Support for 10/100/1000Mbps Ethernet data transfer speeds.
  • Support for Cisco Quality of Service (QoS) features, as well as Advanced Traffic Management (ATM), to ensure that network traffic is properly prioritized and managed.
  • Support for Cisco EnergyWise technology, which helps to reduce energy consumption and costs by allowing administrators to monitor and manage power usage of network devices.
  • Support for Cisco FlexStack, which allows stacking of multiple switch modules to be controlled as a single switching unit

It is important to note that the overall performance of the switch module will also depend on factors such as the quality of the network cables and the network equipment to which it is connected. In addition, the actual performance may vary based on the specific network configuration, the number of connected devices, and the traffic patterns of the network.

It's worth mentioning that the part is an older model, and there might be newer models available with different performance characteristics and capabilities.

Reliability of 48-Ports Switch Module

The WS-X4548-GB-RJ45V Cisco Catalyst 4500 switch module is designed to provide high-reliability network connectivity for data center and campus environments.

Here are several features that contribute to the reliability of This product:

  • Line-rate performance: It is a line-rate module which means it can forward all packets at wire-speed without any packet loss. This means the switch is able to handle high-bandwidth traffic, even during peak usage periods, without slowing down the network or causing packet loss.
  • Quality of Service (QoS) and Advanced Traffic Management (ATM) support: Allows for advanced traffic management, prioritization, and shaping which improves the overall reliability of the network by ensuring critical traffic is given priority.
  • Redundancy: The module supports multiple redundancy features such as Redundant Power Supply (RPS) and Hot Swappable Power supply, which helps to improve reliability by allowing for the replacement of failed components without disrupting the network.
  • Cisco EnergyWise technology: allows to reduce energy consumption and costs by allowing administrators to monitor and manage power usage of network devices. This technology is designed to increase the lifespan of the equipment, and in turn, improve the overall reliability of the network.
  • FlexStack support: which allows stacking of multiple switch modules to be controlled as a single switching unit, providing increased scalability and flexibility. This feature is especially useful in large networks where multiple switches are needed.
  • Built to handle high traffic: The model is designed to handle high-density network traffic, which makes it suitable for data center or campus environments.

It's important to note that the overall reliability of the network also depends on many other factors such as the quality of the network equipment to which it is connected, the quality of the cabling, and the regularity of maintenance and troubleshooting. It's worth mentioning that part is an older model and there may be newer models available with different features and capabilities.

Different Types of Switches

Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).

Unmanaged Switches

The unmanaged switches offer fixed configurations on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.

Managed Switches

The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.

The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.

Smart Switches

Smart switches refer to switches that possess more features than those unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.

Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.

Modular Switches

Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
