Configuring Ethernet Ports Mode Chapter 8
FA4800 User Manual Release 1.9.30 8-17
The following table shows the appropriate configuration for several common
scenarios. Both link sites must be configured with the same parameter:
Configuring Ethernet Ports Mode
The ODU Ethernet port is configured to auto-detect by default and may not
be changed.
The ODU Ethernet port mode is configurable for line speed (10/100BaseT)
and duplex mode (half or full duplex).
An Auto Detect feature is provided, whereby the line speed and duplex
mode are detected automatically using auto-negotiation. Use manual con-
figuration when attached external equipment does not support auto-negoti-
ation. The default setting is Auto Detect.
¾
To configure the Ethernet Mode:
1. From the Configuration menu, choose the site to configure.
The Site Configuration dialog box opens.
2. Click Advanced | Ethernet.
3. In the Ethernet Ports Configuration pane, use the drop-down menu to
choose the configuration.
4. Click Apply to save the changes.

Caution
You should not reconfigure the port that is used for the managing computer
connection, since a wrong configuration can cause a management
disconnection or Ethernet services interruption.
Note
It is possible to close the Ethernet service by disconnecting the Ethernet
port.
If you close the port, you may subsequently be unable to access the
device. If this should occur, a workaround is as follows:
• Connect the system from the remote site
• Connect via other Ethernet port (of the IDU)
• Power down the equipment and connect immediately after power
up (the fastest way is to enter install mode)
