Step 9
Using the network module handle, push the module into place until you feel the edge connector seat
securely into the connector on the router backplane. The network module faceplate should contact the
chassis rear panel.
Step 10
Using a number 1 Phillips or flat-blade screwdriver, tighten the captive mounting screws on the network
module faceplate.
Step 11
Turn on electrical power to the router.
The following warning applies only to routers that use DC power.
Warning
After wiring the DC power supply, remove the tape from the circuit breaker switch handle and
reinstate power by moving the handle of the circuit breaker to the ON position.
Statement 8
Caution
Make sure that the external power supply is disconnected from the NM-1VSAT-GILAT network module
before connecting or disconnecting cables from the RF-IN or RF-OUT connectors. If the external power
supply is connected to the ODU PWR connector while you connect or disconnect cables from the RF-IN
or RF-OUT connectors, you might short-circuit the NM-1VSAT-GILAT network module F connectors.
This may cause the network module to reset itself or lose data.
