4.1.8 LAN connectors
The LAN connectors on the ACU are used for system setup and for connection to the VSAT
modem.
The maximum cable length per connection is 100 m. Depending on the VSAT modem
connected, a LAN connector may be used for modem control.
Cable type: CAT5, shielded.
For information how to configure the LAN network see To configure the LAN network on
page 6-14.
Note
These connectors are normally only for communication within the VSAT system,
not for connection to the Internet. For Internet connection, connect to your
VSAT modem.
Important
The EXPLORER VSAT system is not designed to be connected directly to the
Internet. It must be located behind a dedicated network security device such
as a fire wall.
You should change the default passwords as anyone with access and
malicious intent can render the VSAT system inoperable.
