More Information of this Item

The WS-C3750-48PS-E is a Cisco Catalyst 3750 48-port PoE Manageable Layer 3 Stackable Ethernet Switch. It is a member of the Cisco 3750 series, which is a line of stackable, multi-layer switches that provide high availability, scalability, security, energy efficiency, and ease of operation.

The "48PS" in the model number indicates that the switch has 48 Ethernet ports and four Power over Ethernet (PoE) capable ports, which allows the switch to provide power to devices such as IP phones and wireless access points over the Ethernet cables. The "E" in the model number denotes that it is an enhanced version of the 3750 series switch.

The switch supports advanced features such as Quality of Service (QoS), VLANs, and link aggregation, and it is Layer 3 switch, which means it can support routing protocols, static routing, and advanced filtering capabilities.

It is stackable, which means that multiple switches can be interconnected and managed as a single entity, providing increased capacity, redundancy, and ease of management. The switch also supports SNMP, syslog, and other management protocols, making it easy to monitor and troubleshoot the network.

This switch is suitable for use in enterprise, campus, and branch office networks, and it is ideal for environments that require high availability, security, and network segmentation.


The model Cisco Catalyst 3750 48-port switch is designed to provide high performance and reliability in enterprise networks.

In terms of performance, the switch supports a non-blocking architecture, which means that all 48 ports can operate at wire-speed simultaneously without any performance degradation. Additionally, it supports a variety of features that help optimize network performance such as Quality of Service (QoS) and Link Aggregation Control Protocol (LACP) which allows to bundle multiple physical ports together to form a single logical link, increasing the bandwidth available.

In terms of reliability, the switch supports several features that increase its availability. It can be used in a stackable configuration, where multiple switches can be connected together to form a single logical unit. This allows for redundancy and increased scalability. Additionally, it supports Hot-Standby Router Protocol (HSRP) which allows for automatic failover in the event of a switch failure.

It also supports Cisco StackWise technology, which allows for the switches to work together as a single entity, sharing a single IP address for management and providing redundancy at the management level. This allows for faster recovery and improved network uptime.

The switch also supports advanced security features such as Access Control Lists (ACLs) and advanced Quality of Service (QoS) features to help secure the network and prioritize mission-critical applications.

Interface Provided for Digital Workplace

The WS-C3750-48PS-E Cisco Catalyst 3750 48-port switch provides a variety of interfaces that can be used to connect devices in a digital workplace.

First, the switch has 48 Ethernet ports that support both 10/100/1000 Mbps data rates. These ports can be used to connect devices such as computers, servers, and other network devices to the switch. Additionally, the switch supports Power over Ethernet (PoE) on all 48 ports, which allows for the delivery of power to network devices such as IP phones and wireless access points through the Ethernet cables, eliminating the need for additional power cables.

The switch also provides a management interface, which allows for the configuration and monitoring of the switch. This can be accessed through the Command Line Interface (CLI) using a console cable or remotely through a web interface or Simple Network Management Protocol (SNMP).

In addition, the switch supports Link Aggregation Control Protocol (LACP) and Quality of Service (QoS) which allows for the bundling of multiple physical ports together to form a single logical link, increasing the bandwidth available, and also prioritize mission-critical applications such as Voice and Video.

The switch also supports advanced security features such as Access Control Lists (ACLs) which can be used to control access to the network and protect against unauthorized access.

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 configuration 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 of 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.
