> ### Functional Description

> Broadcom NetXtreme® Gigabit Ethernet adapters connect a PCI, PCI-X (BCM5701 and BCM5703), or PCI Express™ (BCM5751 and BCM5721) compliant system to a Gigabit Ethernet network. The BCM5714 provides an independent PCI-X bus for peripheral connectivity. Broadcom NetXtreme® Gigabit Ethernet adapters incorporate a technology that transfers data at a maximum rate of 1 gigabit per second—10 times the rate of Fast Ethernet adapters.

> Broadcom NetXtreme Gigabit Ethernet adapters target the increased congestion experienced at the backbone and system in today's networks and provide a future upgrade path for systems that require more bandwidth than Fast Ethernet can provide.

> Using the Broadcom teaming software, you can split your network into virtual LANs (VLANs) as well as group multiple network adapters into teams to provide network load balancing and fault tolerance functionality. See Teaming and Broadcom Gigabit Ethernet Teaming Services for detailed information about teaming. See Virtual LANs for a description of VLANs. See Configuring Teaming for instructions on configuring teaming and creating VLANs on Windows and NetWare operating systems.

> ##### Power Management

> Wake on LAN (Magic Packet, Wake Up Frame, specific pattern) is supported at 10/100 Mbps operation only.

> NOTES:

> - Adapter speed connection when the system is down waiting for a wake-up signal is either 10 Mbps or 100 Mbps, but can return to 1000 Mbps when the system is up and running if connected to a 1000 Mbps capable switch. Systems intending to use Wake on LAN (WOL) should be connected to a switch capable of both 1000 and 10/100 Mbps speeds.
> - Broadcom supports Wake on LAN on one adapter in the system at a time.

> ##### Adaptive Interrupt Frequency

> The adapter driver intelligently adjusts host interrupt frequency based on traffic conditions, to increase overall application throughput. When traffic is light, the adapter driver interrupts the host for each received packet, minimizing latency. When traffic is heavy, the adapter issues one host interrupt for multiple, back-to-back incoming packets, preserving host CPU cycles.

> ##### Dual DMA Channels

> The PCI interface on Broadcom NetXtreme Gigabit Ethernet adapters contains two independent DMA channels for simultaneous read and write operations.

> ##### 32-Bit or 64-Bit PCI Bus Master

> Compliant with PCI Local Bus Rev 2.3, the PCI interface on Broadcom NetXtreme Gigabit Ethernet adapters is compatible with both 32-bit and 64-bit PCI buses. As a bus master, the adapter requests access to the PCI bus, instead of waiting to be polled.

> ##### ASIC with Embedded RISC Processor

> The core control for Broadcom NetXtreme Gigabit Ethernet adapters resides in a tightly integrated, high-performance ASIC. The ASIC includes a RISC processor. This provides the flexibility to add new features to the card and adapt it to future network requirements through software downloads. This also enables the adapter drivers to exploit the built-in host offload functions on the adapter as host operating systems are enhanced to take advantage of these functions.

> ##### Broadcom Advanced Control Suite 2

> Broadcom Advanced Control Suite 2 (BACS2), a component of the Broadcom teaming software, is an integrated utility that provides useful information about each network adapter that is installed in your system. The BACS2 utility also enables you to perform detailed tests, diagnostics, and analysis on each adapter, as well as to modify property values and view traffic statistics for each adapter. BACS2 is used on Windows operating systems to configure teaming and to add VLANs. See Using Broadcom Advanced Control Suite 2 for detailed information and instructions.

> ### Supported Operating Systems

> Broadcom NetXtreme Gigabit Ethernet adapters have software support for the following operating systems:

> - Microsoft® Windows® (32-bit and 64-bit extended)
> - Linux® (32-bit and 64-bit extended)
> - MS-DOS®
> - NetWare®
> - Sun Solaris
> - SCO® UnixWare®
> - SCO OpenServer®

> ### Network Link and Activity Indication

> The state of the network link and activity is indicated by the port LEDs adjacent to the RJ-45 connector, as described in Table 1: "Network Link and Activity Indicated by the Port LEDs". Broadcom Advanced Control Suite 2 also provides information about the status of the network link and activity (see Vital Sign).

> Table 1. Network Link and Activity Indicated by the Port LEDs
> Port LED | LED Appearance | Network State
> --- | --- | ---
> Link LED | Off | No link (cable disconnected)
> Continuously illuminated | Link
> Activity LED | Off | No network activity
> Blinking | Network activity
