Power and Innovation of Rack-mountable Switch

The WS-C3750-24PS-S Cisco Catalyst switch is a powerful and innovative switch that offers a range of features and capabilities to enhance the performance and security of networks.

One of the key features of the WS-C3750-24PS-S is its power over Ethernet (PoE) capability. This feature allows the switch to provide power to connected devices, such as IP phones and wireless access points, over the Ethernet cables. This eliminates the need for separate power supplies and reduces the overall cost and complexity of the network.

Another key feature of the switch is its ability to support advanced security features. The switch supports features such as access control lists (ACLs), port security, and IEEE 802.1X authentication to help protect the network from unauthorized access and security threats.

In addition, the WS-C3750-24PS-S also supports innovative features such as Cisco StackWise technology, which allows multiple switches to be connected together and managed as a single entity for increased scalability and ease of management. The switch also supports Cisco EnergyWise, which allows network administrators to monitor and manage the power consumption of network devices to reduce energy costs.

The switch also supports Cisco's proprietary protocol, FlexStack, which allows administrators to stack multiple switches and manage them as a single logical switch. This provides increased scalability, and ease of management and also allows for faster switching and routing between the devices.

The WS-C3750-24PS-S also supports the Cisco IOS software which provides a wide range of features and capabilities for managing and securing networks. This includes features such as Quality of Service (QoS), Link Aggregation Control Protocol (LACP), and Virtual Private Network (VPN) support.

Resiliency and High Availability

The WS-C3750-24PS-S Cisco Catalyst switch supports various resiliency and high availability features to ensure that the network stays up and running even in the event of a failure.

One such feature is Redundant Power Supply (RPS) which allows the switch to continue operating even if one of the power supplies fails. This ensures that the switch continues to operate and provides network connectivity even in the event of a power supply failure.

Another feature is StackWise technology which allows multiple Cisco Catalyst 3750 switches to be connected and operated as a single logical unit. This allows for increased resiliency as if one switch in the stack fails, the other switches in the stack can continue to provide network connectivity.

Cisco FlexStack Plus is also available for this switch which increases the stack bandwidth and allows more switches to be stacked. This increases the scalability and resiliency of the network.
