Broadcom Advanced Control Suite
The Broadcom 440X Fast Ethernet Controller connects a PCI workstation to a 10/100 Mbps Ethernet network. The BCM440X adapter or BCM440X LAN on Motherboard is a fully-integrated 10/100 Ethernet MAC/PHY. The MAC also supports management functions including RMON, Ethernet-like MIB, and IEEE802.3M Ethernet MIB.
Figure 1. The Broadcom 440X Fast Ethernet Controller
The following is a list of the Broadcom 440X Fast Ethernet Controller features for all supported operating systems:
The following table shows the four Ethernet LED outputs that BCM440X provides to indicate Link Integrity (LED0_L), Activity (LED1_L), Speed (LED2_L), and Collision (LED3_L).
LED | Description |
0 | Ethernet Link Integrity: Indicates Ethernet link status. This output is driven low when the link is good. |
1 | Ethernet Activity: This output is driven low for approximately 80 ms each time there is either transmit or receive activity while in the link pass state. |
2 | Ethernet Speed: This output is driven low when the Ethernet MAC and PHY are operating in 100BASE-T mode, and disabled when operating in 10BASE-T mode. |
3 | Ethernet Collision: This signal is stretched to make it suitable for LED display and driven low to indicate a collision. |
The Broadcom Advanced Control Suite is a graphics user interface with the following functions. Refer to "Broadcom Advanced Control Suite " for additional information.
