Information About the NM-1VSAT-GILAT Network Module
•
To avoid damaging the NM-1VSAT-GILAT network module, disconnect the power supply from the
ODU PWR connector on the NM-1VSAT-GILAT network module
before
you attempt any of the
following actions:
–
Connecting a cable to the RF-IN or RF-OUT connector
–
Disconnecting a cable from the RF-IN or RF-OUT connector
–
Inserting the NM-1VSAT-GILAT network module into the router chassis
–
Removing the NM-1VSAT-GILAT network module from the router chassis
•
After completing the hardware installation, moving the router with the installed NM-1VSAT-GILAT
network module may require longer radio frequency (RF) cables. Depending on the ODU type and
the additional length required for the cables, you may need a technician to install line amplifiers.
Contact your satellite service provider if you plan to extend your cables by more than 35 feet (11 m).

are the terrestrial WAN connections that are also commonly used to connect
VSAT routers to the Internet or an intranet. A terrestrial WAN connection can be used to back up a
satellite link or can serve as a primary link that is backed up by a satellite link.
