Built on the foundation of Twisted Pair Gigabit Ethernet technology, the C9400-LC-48U ensures efficient and reliable data transfer across the network. The use of twisted pair cabling reduces electromagnetic interference, enhancing the overall signal integrity.

In the era of sustainability, energy efficiency is a critical consideration for any network infrastructure. The C9400-LC-48U incorporates Energy Efficient Ethernet (802.3az) standards, allowing for intelligent power management. This not only reduces energy consumption during periods of low network activity but also contributes to cost savings and a smaller environmental footprint.

The inclusion of Universal Power over Ethernet (UPoE) in the C9400-LC-48U is a game-changer. This technology enables the delivery of up to 60 watts of power per port, providing a one-cable solution for both data and power. This not only simplifies cable management but also opens up new possibilities for deploying network devices in locations where traditional power sources may be limited.

The C9400-LC-48U's 60 Watt Module adds a layer of modularity to its design, allowing organizations to tailor power delivery based on specific requirements. This flexibility is particularly valuable in dynamic environments where power needs may vary across different network segments.

With its 48 RJ-45 ports and support for 10/100/1000Base-T, the C9400-LC-48U significantly enhances connectivity within a network. This is especially valuable in environments with a large number of devices requiring simultaneous and reliable connections.

The ability to support 10/100/1000Base-T network standards ensures that the switch can adapt to varying speed and bandwidth requirements. This versatility is crucial for accommodating different types of devices and applications, from basic data transfer to bandwidth-intensive tasks.

The integration of twisted pair Gigabit Ethernet technology enhances the reliability of data transmission. Twisted pair cables mitigate the impact of electromagnetic interference, contributing to stable and consistent communication between devices.

The Energy Efficient Ethernet (EEE) 802.3az standards contribute to the switch's energy efficiency. By dynamically adjusting power usage based on network activity, the C9400-LC-48U minimizes its environmental footprint and operating costs, aligning with the growing emphasis on sustainability in modern business practices.

The Universal Power over Ethernet (UPoE) 60 Watt Module sets the C9400-LC-48U apart in terms of power delivery. This feature is particularly advantageous for supporting devices with higher power requirements, such as pan-tilt-zoom cameras, advanced access points, and other IoT (Internet of Things) devices. The switch's robust PoE capabilities enhance its role in powering and managing diverse networked devices.

The Cisco Catalyst 9400 Series 48 Ports Line Card Expansion Module is designed to provide high performance and reliability in a network expansion module.

In terms of performance, the model provides 48 Gigabit Ethernet ports that can operate at wire speed, meaning that the ports can process data at the full speed of the network. Additionally, the line card supports advanced Quality of Service (QoS) features, which allow network administrators to prioritize different types of traffic and ensure that critical applications receive the necessary bandwidth.

In terms of reliability, the model is designed to be fully redundant and to support various resiliency protocols like Link Aggregation Control Protocol (LACP) and Cisco StackWise-480 technology for fast failover. This means that in the event of a hardware failure or other issue, the line card will continue to operate without interruption and traffic will be redirected to ensure continuity of service.

Additionally, the model also supports Network resiliency features like FlexLinks which provide fast convergence in case of a link failure, and a hitless Failover feature for the wireless controller which helps to prevent wireless client drop during switchover.

The C9400-LC-48U also supports advanced power management features to help reduce energy consumption, which makes it a more environmentally friendly and cost-effective option for large-scale networks.
