6-28 Chapter 6: Configuration 98-148248-C
Static IP or DHCP Client
If you select DHCP client the network IP address and sub-net mask must be provided by a
DHCP server on that network. If you select Static IP address you must specify a unique IP
address and a sub-net mask.
DHCP Server Settings
On LAN ports 3 and 4 you can select to run a DHCP server. Select the check box DHCP
Server. The DHCP server settings are only displayed and can be selected when the port
mode is set to Static, otherwise the DHCP server settings are not shown. The DHCP start
and end addresses must be on the same network as the port's static IP.
DNS setup
If you have access to a Domain Name Server (DNS) you can specify the address of the e-
mail server by using the server name instead of its IP address. This can be used in Outgoing
mail server in E-mail setup on page 6-29. You may statically specify the address of one or
two DNS. Select the DNS source as static and fill in IP address or addresses.
Alternatively, if the DHCP server can provide a DNS address and you have selected DHCP
client above, then select the same LAN as your DNS source.
Gateway setup
If the ACU needs to communicate with network units outside the specified sub-nets, you
must specify a default gateway (typically a router). The default gateway can be set as a
static IP address. Then set the default gateway source to static and enter the IP address of
the default gateway. To remove the default gateway set it to 0.0.0.0. Alternatively, if the
DHCP server is able to provide a default gateway address and you have selected DHCP
client above, then select the same LAN as your default gateway source.
Zeroconf Settings
On LAN ports 1,3 and 4 you can choose to add a zeroconf address in the network
(169.254.0.0). This zeroconf address will be in addition to the existing static or DHCP IP
address. One port at a time can be enabled. Zeroconf allows devices to connect to a
network automatically.
LAN Port 3 LAN port 3 is the service port. The default IP address is
http://192.168.0.1; the current value can be displayed in the ACU
display. It is recommended to connect LAN port 3 to the front port (via
rear connector, for access to the service port from the rack front.
LAN port 3 can be set to the mode Static or Switched with port 1,
DHCP server can be selected (default) or DHCP client.
LAN Port 4 LAN port 4 can be used to connect to the vessel’s LAN.
LAN port 4 mode can be set to Static, DHCP client (default) or DHCP
server.
