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 choose 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 6-27. 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 your 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).
LAN Port 2 LAN port 2 is used for Internet access or Inmarsat Network Service
Device (NSD).
LAN Port 3 LAN port 3 is dedicated as the service port. By default this port has the
IP address http://192.168.0.1; the current value can be displayed in the
ACU display. In a 19” rack mount it is recommended to connect LAN
port 3 to the front port (via rear connector, see the figure ACU
(connector panel) on page 4-1), 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.
