Network Configuration
Dual Dome Port Configuration
If a second TracPhone system is installed as a backup, one of the “User
Ethernet” ports on that secondary system’s ICM must be connected to
the “User Ethernet 4” port on the primary system’s ICM.
Figure 6-15 Dual Dome Wiring (Example)
In this dual-dome configuration, the vessel’s phones and network
devices connect to the primary system. The “User Ethernet 1, 2, and 3”
ports on the primary system’s ICM remain configured for the LAN.
The “User Ethernet” ports on the secondary system’s ICM are
configured as a bridge to the primary system’s ICM. Whenever the
primary system loses its connection to the mini-VSAT Broadband
service (e.g., its view of the satellite becomes blocked), all voice and
data traffic will automatically get routed through the “User Ethernet
4” port to the secondary system.
Important!
Contact KVH Technical Support before you configure the secondary
ICM (see
“Technical Support” on page 110
). KVH will need to modify
a setting on the secondary ICM over the air to support a dual dome
configuration.
