Dual-Port Gigabit Server Adapter

The Dell Broadcom 5720 is a dual-port Gigabit Ethernet card designed for server installations. It connects through a PCI Express host interface and provides two RJ-45 ports for wired network links. This new plug-in card suits administrators expanding connectivity in compatible Dell server chassis.

Practical Limits of 10/100/1000Base-T

The card operates at 10, 100, or 1000 Mbps over twisted-pair cabling. Each port negotiates the highest common speed with the linked switch or device. Cable runs must stay within the 100-metre limit defined for copper Ethernet. Bandwidth tops out at one gigabit per second per port.

Verify Slot and Driver Support

Confirm the server has an available PCI Express slot that matches the card's electrical and physical requirements. Check that the operating system or hypervisor includes or supports a driver for the Broadcom 5720 controller. Ensure the chassis can accommodate a standard-height plug-in card.

Questions about this item

Should I pick the single-port or dual-port version of the Broadcom 5720?

This model is the dual-port 557M9; it provides two RJ-45 connections on one PCI Express card.

What does the 10/100/1000Base-T rating mean once the card is installed in a server?

Each port auto-negotiates at 10, 100 or 1000 Mbps over twisted-pair cabling, so the link runs at the highest speed both ends support.

The card uses a PCI Express host interface — what does that cap in practice?

The PCI Express host interface connects the two Gigabit ports to the server bus; each port is limited to 1000 Mbps by the 10/100/1000Base-T PHY.
