Chapter 33 Connecting Cisco IP VSAT Satellite WAN Network Modules How to Install, Connect, or Replace the NM-1VSAT-GILAT Network Module Steps To perform OIR of the NM-1VSAT-GILAT network module in your router, follow these steps: Step 1 Step 2 Step 3 Initiate a console session with your router. Enter satellite interface configuration mode and shut down the interface: Router> enable Router# configure terminal Router(config)# interface satellite slot/0 Router(config-if)# shutdown Router(config-if)# end Router# Disconnect the power supply cable from the ODU PWR connector on the NM-1VSAT-GILAT network module. 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. Step 4 Step 5 Step 6 (Optional but recommended) Label the RF cables "RF-IN" and "RF-OUT." Disconnect the cables from the RF-IN and RF-OUT connectors on the NM-1VSAT-GILAT network module. Using a number 1 Phillips or flat-blade screwdriver, loosen the captive mounting screws on the network module faceplate. Caution To avoid damaging the network module, always handle the network module by the handle or faceplate. Do not touch the circuit board. Step 7 Using the module handle, pull the network module from the router slot. (See Figure 33-8.)
