Dual-port Gigabit Ethernet PCIe card with two RJ-45 ports for server networking

  • Dual RJ-45 ports connect servers at 10/100/1000 Mbps
  • PCI Express host interface adds gigabit networking without proprietary slots
  • Two twisted-pair ports share one plug-in card to save server bays
  • Broadcom 5720 controller handles 10/100/1000Base-T traffic on each port
  • Plug-in card form factor fits standard server expansion slots

Dell 5720 Dual-Port Gigabit NIC

The Dell 5720 is a PCI Express plug-in card that adds two RJ-45 ports to a server. It operates at 10/100/1000Base-T speeds over twisted-pair cabling. The card is supplied new and carries the manufacturer part number 0FCGN. It is designed for server environments that need additional wired network connections.

Suited for servers needing two gigabit links

This module fits administrators who want a simple dual-port copper upgrade for rack or tower servers with a free PCI Express slot. It is not for systems that require fibre uplinks, 10-gigabit throughput, or more than two ports. Buyers needing SFP+ cages, higher bandwidth, or four-port density should look at other adapters.

Two 1000 Mbps ports with 10/100 fallback

Each port negotiates 10, 100, or 1000 Mbps, so the card handles standard gigabit traffic and steps down for legacy 10/100 switches. Total headroom is limited to the two gigabit links provided by the Broadcom 5720 controller. Environments that need link aggregation beyond two ports or multi-gigabit speeds will exceed the card's capacity.

Questions about this item

What free PCI Express slot does the Dell 5720 card need to install?

The card plugs into any available PCI Express slot on a compatible server motherboard.

Will the two RJ-45 ports negotiate down to 10 or 100 Mbps for legacy switches?

Yes, the 10/100/1000Base-T ports auto-negotiate to the highest speed the link partner supports.

Which link lights confirm the card is passing traffic at gigabit rate?

Each port has activity and speed LEDs; a steady green speed LED indicates a 1000 Mbps link.
