DELL 430-4407 Broadcom 5720 dual-port Gigabit network card

SKU CH-WG48-DDSE1 MPN 430-4407

Dual-port Gigabit network adapter with 10/100/1000 Ethernet transceivers and PCI Express interface

  • Dual-port Gigabit connectivity for redundant network links
  • Broadcom BCM5720 controller delivers reliable 10/100/1000 performance
  • PCI Express interface enables fast desktop and server integration
  • IEEE 802.3 compliant MACs ensure broad network compatibility
  • Factory-sealed new unit with Dell technical support eligibility

Dual-port Gigabit NIC for desktops and servers

The DELL 430-4407 Broadcom 5720 adapter adds two 10/100/1000 Ethernet connections to a desktop or server through a PCI Express slot. It uses the Broadcom BCM5720 controller with dual triple-speed MACs and PHYs. The card is supported by Dell Technical Support when installed in a Dell system.

Sustained throughput with on-chip buffering

Each port handles continuous traffic at 10, 100, or 1000 Mbps using an on-chip memory buffer that absorbs bursts without host intervention. Dual independent MACs allow both links to operate at line rate simultaneously during prolonged transfers. The PCI Express bus interface moves frames to system memory with low latency under steady load.

IEEE 802.3 compliance and copper distance limit

The adapter conforms to IEEE 802.3 for 10BASE-T, 100BASE-TX, and 1000BASE-T on twisted-pair copper cabling. Practical link distance is limited to the 100-metre channel maximum defined by the standard. Buyers needing fibre connectivity or speeds beyond 1 Gbps must select a different adapter.

Questions about this item

How much power does the dual-port 5720 card draw when both 1000 Mbps links run all day?

The Broadcom 5720 controller integrates dual 10/100/1000 transceivers and on-chip memory buffer on a PCI Express bus, a design that keeps power draw low during continuous full-speed operation.

Which slot type must my motherboard provide for the 430-4407 to install and function?

The adapter uses a PCI Express bus interface, so your system needs an available PCIe slot of compatible length and electrical width.

Will the 430-4407 negotiate correctly with my older 10 Mbps and 100 Mbps switches?

Yes, each port is IEEE 802.3 compliant and supports triple-speed 10/100/1000 operation, so it auto-negotiates down to legacy 10 and 100 Mbps links.
