5. Click Start to flash the LED.
The LED flashes for the specified number of seconds. Find the Ethernet port with
the flashing LED and make note of its device name in PROSet.
6. When the flashing stops, you can click Start to flash the LED again or Close to
dismiss the Identify Adapter dialog box. If necessary, repeat steps
additional adapters.

Configuring Link Speed and Duplex Mode

By default, Ethernet ports onU575 Ethernet PCI adapters and embedded Ethernet PCI
adapters are configured to autonegotiate the best speed for a connection. On a
network that operates at 10 or 100 megabits per second (Mbps), automatic settings can
result in unreliable connections and inaccurate reporting of link activity and duplex
mode. For reliable operation, manually configure the link speed and duplex mode for
all Ethernet PCI adapters connected to networks that operate at 10 or 100 Mbps.
When you manually set these values, make sure that the values are identical for the
Ethernet port and the link partner to which it connects, and that the settings for all
Ethernet ports in one team are the same.

1. For Ethernet adapters or ports connected to networks
running at 1 gigabit per second (Gbps), rely on
autonegotiation. Do not manually configure 1-Gbps
operation.
2. Express5800/320Ma systems support 1-Gbps line
speed only in full-duplex mode.
