Ethernet Port Configuration
The Scanner Appliance uses Ethernet auto negotiation on scanning and management ports. Most network devices have auto negotiation enabled. Locked-down port policies with auto negotiation disabled, such as forcing speed, duplex, and link capabilities, are outdated. This is due to the maturity of the auto negotiation technology as well as the rate of adoption by product vendors and consumers over many years.
In the rare and unusual case where auto negotiation is disabled, Ethernet port configuration on the Scanner Appliance is necessary to ensure that link syncing occurs between the Scanner Appliance and its link partners. The Ethernet port links on the Appliance may be set to full-duplex 1GbaseT, 100baseT or 10baseT, or half-duplex 100baseT or 10baseT. The LAN and WAN port links (for split network configuration) may be set. The port link configuration on the Scanner Appliance must match the same configuration on the link partners. For example, if you have 100baseT full-duplex forced on devices, the same configuration must be enabled on the Appliance.
In the absence of auto negotiation, link syncing between link partners may not occur and the link may not come up. Consequently, the Scanner Appliance data transmission may be slow and there may be high packet loss, leading to unreliable scan results.
Perform the following steps to configure Ethernet Port:
- Select the SETUP NETWORK menu option
- Press the Down arrow to advance through the menu options. When the ETHERNET PORT SETTINGS menu option displays, press ENTER.
- The LAN PORT LINK option is displayed along with the LAN port link setting in effect. Press the Right arrow to advance through the available port link settings.
Use the Left arrow to advance through the settings in reverse order. To quit this procedure and return to SETUP NETWORK, press the Up arrow two times.

the configuration setting. Go to Step 9 unless WAN port configuration is necessary for split network configuration.
Split Network Configuration: When the Scanner Appliance has a split network
configuration, you have the option to configure the WAN port link setting. To do this, follow the steps below. - Press the Down arrow one time. The WAN PORT LINK option is displayed along
with the WAN port link setting in effect. - Press the Right arrow to advance through the available port link settings.
Use the Left arrow to advance through the settings in reverse order. To quit this procedure and return to SETUP NETWORK, press the Up arrow two times.
