This section describes the network-related configuration.
11.1 Ethernet Interface Configuration
The device's Ethernet connection can be configured, using the ini file parameter
EthernetPhyConfiguration, to one of the following modes:

Manual:
•
10Base-T Full-Duplex
•
100Base-TX Full-Duplex
•
1000Base-TX Full-Duplex

Auto-Negotiation: chooses common transmission parameters such as speed and
duplex mode
The Ethernet connection should be configured according to the following recommended
guidelines:

When the device's Ethernet port is configured for Auto-Negotiation, the opposite port
must also operate in Auto-Negotiation. Any mismatch configuration can yield
unexpected functioning of the Ethernet connection.

When configuring the device's Ethernet port manually, the same mode (i.e., Full
Duplex) and speed must be configured on the remote Ethernet port. In addition, when
the device's Ethernet port is configured manually, it is invalid to set the remote port to
Auto-Negotiation
. Any mismatch configuration can yield unexpected functioning of the
Ethernet connection.

It's recommended to configure the port for best performance and highest bandwidth
(i.e., Full Duplex with 1000Base-TX), but at the same time adhering to the guidelines
listed above.
Note: For remote configuration, the device should be in the correct Ethernet setting
prior to the time this parameter takes effect. When, for example, the device is
configured using BootP/TFTP, the device performs many Ethernet-based
transactions prior to reading the
ini file containing this device configuration
parameter. To resolve this problem, the device always uses the last Ethernet
setup mode configured. In this way, if you want to configure the device to
operate in a new network environment in which the current Ethernet setting of
the device is invalid, you should first modify this parameter in the current
network so that the new setting holds next time the device is restarted. After
reconfiguration has completed, connect the device to the new network and
restart it. As a result, the remote configuration process that occurs in the new
network uses a valid Ethernet configuration
11.2 Ethernet Interface Redundancy
The device supports an Ethernet redundancy scheme. At the beginning of the start-up
procedure, the device tests whether the ‘primary’ Ethernet interface is connected, by
checking the existence of the Ethernet link carrier. If it's connected, the start-up procedure
commences as usual. If not, the start-up application tries the ‘secondary’ Ethernet
interface. If this interface is connected, the whole start-up procedure is performed using it.
If both interfaces are not connected, the start-up procedure commences using the
parameters, tables, and software residing on the device's non-volatile memory. Note that
Ethernet switchover occurs only once during the start-up procedure (at the beginning). If
