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 

 to locate 

additional adapters.

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.

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.

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.
