• StackWise Plus Technology: Enables stacking of up to nine switches with a 64 Gbps stacking bandwidth, simplifying management and enhancing resiliency.
• Dual Redundant Power Supplies and Fans: Ensures high availability and reliability by providing failover power sources and cooling mechanisms.
• Cisco StackPower Technology: Innovative power sharing feature that allows power resources to be distributed across stack members, increasing efficiency and redundancy.
• Hardware-Based Security: Incorporates Media Access Control Security (MACsec) for encryption of data at Layer 2, safeguarding against eavesdropping and tampering.
• Flexible NetFlow: Enables detailed traffic analysis and monitoring, improving network visibility and troubleshooting capabilities.
• Management Ports: Includes USB Type-A and Type-B ports for storage and console access respectively, plus an out-of-band Ethernet management port for dedicated control.
• Backward Compatibility: Maintains investment protection with full interoperability with all other Cisco Catalyst 3750 Series switches.

Performance and Scalability

The WS-C3750X-48PF-L switch is designed to provide high throughput and low latency across enterprise networks. The 64 Gbps stacking bandwidth via StackWise Plus technology enables seamless integration and stacking of up to nine switches, allowing network managers to simplify configuration and management while ensuring high availability. This stacking capability effectively transforms multiple individual switches into a single logical unit, enhancing network resiliency and simplifying maintenance.

Furthermore, Cisco StackPower technology introduces a unique innovation by enabling power sharing among stacked switches. This feature optimizes power utilization, reduces downtime, and allows for flexible power resource management across the entire stack.

Advanced Security Features

Security is a fundamental concern for enterprise networks, and the WS-C3750X-48PF-L addresses this with hardware-accelerated Media Access Control Security (MACsec). This technology encrypts traffic directly at Layer 2, preventing unauthorized access, eavesdropping, and data manipulation. Additionally, flexible NetFlow supports detailed traffic analysis, enabling network administrators to detect anomalies and potential threats promptly.

Power Over Ethernet Plus (PoE+) Benefits

The availability of 48 PoE+ ports capable of delivering 30W each makes this switch ideal for powering a wide range of network devices without the need for additional power adapters or outlets. This simplifies installation and reduces cabling complexity and infrastructure costs. Devices such as IP cameras, VoIP phones, wireless access points, and building automation sensors benefit from reliable power delivery combined with high-speed data connectivity.

Ease of Management and Deployment

Cisco has designed the WS-C3750X-48PF-L to be easy to deploy and manage. Its USB ports facilitate quick storage of configurations and firmware images, while the dedicated out-of-band Ethernet management port allows for secure and isolated switch administration. The integrated web interface, command-line interface (CLI), and support for Cisco Prime Infrastructure and Cisco Network Assistant provide multiple options for monitoring and controlling the network environment.

Applications and Use Cases

• Enterprise Networks: Ideal for campus core and distribution layers where scalability and reliability are paramount.
• Power-Hungry Devices: Efficiently powers a variety of PoE-enabled devices such as IP phones, wireless access points, and video surveillance equipment.
• High-Density Environments: Suitable for large office buildings, data centers, and branch offices requiring high port density and flexible uplink options.
• Secure Networking: Supports stringent security policies and hardware encryption to protect sensitive organizational data.
