ANAGEMENT
Adapter speed connection when the system is down waiting for a wake-up signal may be at 10 Mbps or 100 Mbps, but can
return to 1000 Mbit/s 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.
NOTES:
• For specific systems, see your system documentation for WOL support.
• WOL is supported in Broadcom NetXtreme II BCM5708 devices with silicon revisions of B2 or later. For more
information, see

REQUENCY
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.

ROCESSOR
The core control for Broadcom NetXtreme II adapters resides in a tightly integrated, high-performance ASIC. The ASIC
includes a RISC processor. This functionality provides the flexibility to add new features to the card and adapts it to future
network requirements through software downloads. This functionality 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 3 (BACS), 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 BACS 3 utility also enables you
to perform detailed tests, diagnostics, and analyses on each adapter, as well as to modify property values and view traffic
statistics for each adapter.
Microsoft .NET Framework 2.0 includes the runtime and associated files needed to run BACS 3, and must be installed on
your system in order for BACS 3 to operate. For optimal performance of BACS 3, Broadcom recommends .NET Framework
2.0 SP1, .NET Framework 3.0 SP1, or .NET Framework 3.5, depending on your operating system.
