WS-C3750E-48PD-S Cisco Catalyst 3750E 48 Ports Managed Refurbished

Introduction to the 48 Ports Switch

The WS-C3750E-48PD-S is a member of the Cisco Catalyst 3750E Series of switches. It is a stackable, multilayer Ethernet switch that provides 48 Fast Ethernet ports and supports Power over Ethernet (PoE).

The switch is designed for enterprise-class access and distribution layer deployments in enterprise wiring closets, as well as for use in core or aggregation layers of enterprise or service provider networks. It can be used in a variety of network environments, including traditional campus, data center, and branch office networks.

One of the main features of the model is its support for PoE, which allows it to provide power to devices such as IP phones, wireless access points, and video cameras over the Ethernet cables that connect them to the network. This can help reduce the need for separate power supplies and electrical outlets for these devices.

The switch is also stackable, which means that it can be connected to other 3750E Series switches to create a single, logical switch with a higher port density and increased performance. It supports Cisco StackWise Plus technology, which allows the switches to be connected together using special stack cables, and provides a single, unified management interface for the entire stack.

Performance and Reliability

This Model is a high-performance and reliable Ethernet switch that is designed to meet the needs of enterprise-class networks. It has a number of features that contribute to its performance and reliability:

• High port density: With 48 Fast Ethernet ports, the model can support a large number of devices and connections.
• Stackable design: The switch can be connected to other 3750E Series switches to create a single, logical switch with increased port density and performance.
• Multilayer switching: The model supports multilayer switching, which means it can perform both layer 2 (data link) and layer 3 (network) functions. This allows it to handle more complex network environments and traffic patterns.
• Quality of Service (QoS): The switch supports QoS, which allows it to prioritize different types of traffic and ensure that important traffic, such as voice or video, is given priority over less important traffic.
• Security: The model supports a variety of security features, including access control lists (ACLs), authentication, and encryption, to help protect the network from unauthorized access and attacks.
• Redundancy and resiliency: The switch supports a number of features to help ensure reliable operation, including stackable design, hot-swappable power supplies and fans, and redundant management modules.

Network Management

The WS-C3750E-48PD-S Cisco Catalyst 3750E 48 Ports Managed Switch can be managed through a variety of network management tools. These tools allow for the configuration, monitoring, and troubleshooting of the switch and its connected devices.

One way to manage the switch is through the Cisco Network Assistant (CNA), which is a software application that simplifies the configuration and troubleshooting of Cisco network devices. CNA provides a user-friendly interface and wizards that guide you through the configuration process, making it easy for network administrators to set up and maintain the switch.

Another option is Cisco Prime Infrastructure, which is a comprehensive network management solution that allows you to manage and monitor your entire network from a single console. Prime Infrastructure provides real-time monitoring, automated troubleshooting, and detailed analytics, making it an ideal solution for large networks.

The switch also supports command-line interface (CLI) which can be accessed via Telnet or SSH, for advanced users and configuration. CLI is a powerful tool for configuring and managing the switch, but it requires knowledge of Cisco IOS commands and syntax.

The switch also supports SNMP (Simple Network Management Protocol) for monitoring and management. This allows you to monitor the switch's performance and status using SNMP-based network management systems.

Additionally, the switch can be integrated with other network management systems using the Cisco Embedded Event Manager (EEM) or third-party network management systems using the CISCO-STACKWISE-MIB.
