Network Adapter Dell Broadcom 5720 DP 1Gb PCIe — 1 GbE dual-port PCIe

The Dell Broadcom 5720 DP 1Gb PCIe network adapter is a high-performance dual-port Gigabit Ethernet card engineered for professional server and workstation environments. This adapter utilizes the reliable Broadcom controller architecture to deliver stable 1 Gb/s connectivity across two RJ-45 ports. Designed for seamless integration into PCIe slots, it provides essential networking capabilities for data centers and office infrastructures requiring consistent wired performance.

Advantages

This network adapter offers significant benefits for system administrators and IT professionals seeking to enhance network throughput and redundancy. By providing two independent Gigabit ports on a single card, it allows for efficient load balancing and failover configurations. The hardware offload features integrated into the Broadcom controller help reduce CPU utilization, ensuring that the host system can dedicate more resources to critical applications while maintaining high-speed data transfers.

Suitable for

• Server virtualization environments requiring multiple network segments.
• Workstations needing reliable, high-speed wired network connectivity.
• Data center infrastructure upgrades for improved network manageability.
• Systems requiring network redundancy through link aggregation or failover.

This adapter may not be suitable for high-speed fiber optic networks as it is strictly designed for copper RJ-45 connections. Additionally, it is not intended for consumer-grade laptops or small form factor devices that lack a standard PCIe expansion slot.

Key specifications

• Interface: PCIe
• Ports: Dual-port RJ-45
• Data Rate: 1 Gb/s per port
• Controller: Broadcom 5720
• Compatibility: Servers and workstations with PCIe slots

How to use

To install the Dell Broadcom 5720 DP 1Gb PCIe network adapter, power down your server or workstation and disconnect all power cables. Open the chassis and locate an available PCIe slot. Carefully insert the card into the slot until it is firmly seated, then secure the bracket to the chassis. Once installed, reconnect the power and boot the system. The operating system should automatically detect the hardware, though you may need to download and install the latest drivers from the official Dell or Broadcom support websites to ensure optimal performance and feature availability.

What to consider before purchase

• Verify that your server or workstation has an available PCIe slot.
• Ensure your operating system is compatible with Broadcom 5720 drivers.
• Confirm that your network infrastructure supports 1 Gb/s RJ-45 connections.

Usage recommendations: For best results, ensure that the network cables used are Cat5e or higher to support full Gigabit speeds. Regularly check for firmware updates to maintain security and compatibility with your network environment.
