It contains the following sections:. The ODU receives and sends signals to a satellite, and the satellite sends and receives signals from an earthbound central hub, which controls the entire operation of the satellite network. Therefore, you must take one of the following actions:.
The Sat Kit includes the dish antenna equipment and an external power supply. Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 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. Before performing the tasks in this document, you should understand the following concepts:. 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.
Local network at VSAT; for example, a branch office network connected to an Ethernet port on the router. At a high level, the many components of an enterprise satellite communications network can be divided into three categories:. Placed in orbit around the earth, a satellite is a specialized repeater that receives radio-frequency signals from earth stations and retransmits them to other earth stations.
The satellite also amplifies the signals and switches the frequencies between the uplink and the downlink carriers. Gilat SkyEdge systems use geostationary satellites with a fixed satellite-to-earth delay of about ms. The central hub—sometimes referred to as the "master earth station" but most often simply called the "hub"—contains many components, including:. Note Throughout this document, the "hub" refers specifically to a Gilat SkyEdge hub.
A very small aperture terminal VSAT is an earth station that can be divided into two areas:. The IDU components vary, depending on the functions required, but the components typically include these items:. The ODU is typically mounted on a building roof or outer wall, or placed on the ground. Amplifies and converts high-frequency satellite signals into lower-frequency signals.
Filters out transmitted signals so that only signals received from the satellite enter the LNB. Separates transmitted signals from received signals, which have different polarization and frequency. Amplifies and converts the low-frequency signals from the IDU to high-frequency signals for transmission across the satellite link. Concave dish surface which focuses the energy received from the satellite to the feed horn and which transfers the energy transmitted by the feed horn to the satellite.
The outbound direction applies to signals transmitted from the hub to the VSAT. From the VSAT perspective, the outbound direction is the receive path. The inbound direction applies to signals transmitted from the VSAT to the hub. From the VSAT perspective, the inbound direction is the transmit path. Inbound signals include user data and retransmission requests. Check ODU power supply connections. DVB 3 outbound 4 receiver is locked.
The VSAT parameters are configured incorrectly. The network module is not properly connected to the LNB. There is a hub failure, or the hub is configured incorrectly. Contact your satellite service provider. Inbound 8 transmission is in progress. If you are concerned about the TX LED being off, then try to ping the hub or another destination on the other side of the satellite link.
If the TX LED does not flicker during the ping, then the network module is not attempting to send data to the hub. Verify that the network module is properly installed in the router chassis. This section contains the following procedures, each of which may or may not be required, depending on which tasks your satellite service provider performs for you:.
Typically, a satellite service provider installation technician installs the ODU, connects RG cables to the dish antenna, and runs the RG cables to the area near the router.
Contact your satellite service provider for ODU and cable installation information. See Figure 5. Note If an installation technician has already connected a power supply to the ODU, then do not perform this task.
Only use the power supply provided in the Gilat ODU kit. See Figure 6. Step 2 Connect the power supply to a general-purpose electrical outlet. For the United States, see Figure 6. For Europe, see Figure 7. Complete one of the following tasks, depending on whether or not your router supports online insertion and removal OIR :. The online insertion and removal OIR feature enables some Cisco modular access routers to support the replacement of network modules without switching off the router or affecting the operation of other interfaces.
Also, routing information is maintained during OIR of network modules. If you remove a network module, install another network module exactly like it in its place. Step 1 Initiate a console session with your router. Step 2 Enter satellite interface configuration mode and shut down the interface:. Step 6 Using a number 1 Phillips or flat-blade screwdriver, loosen the captive mounting screws on the network module faceplate. Step 7 Using the module handle, pull the network module from the router slot.
See Figure 8. Step 8 Align the replacement network module with the guides in the chassis walls or slot divider and slide it gently into the slot. See Figure 9. 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 13 Confirm that the network module LEDs come on.
Step 14 Initiate a console session with your router. Step 15 Enter satellite interface configuration mode, and enable the satellite interface:.
If your router supports OIR, do not perform this task. Step 4 Turn off electrical power to the router. Leave the power cable plugged in to channel ESD voltages to ground. Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.
Statement 7. Timesaver Label the cables or prepare a network cabling diagram before removing cables. Step 5 Remove all network cables, including telephone cables, from the rear panel of the router. See Figure 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.
Step 11 Turn on electrical power to the router. 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. Step 14 Reconnect all other network cables, including telephone cables, to the rear panel of the router.
