LNB 1:1 Redundant Switch System Overview
1.1 Operation
The LNB 1:1 Redundant Switch system (RSW) provides LNB redundancy by automatically switching to a
backup LNB in the event of an LNB failure. During normal operation, there is one Active LNB and one
Standby LNB which are both monitored continuously. LNB health monitoring is accomplished by watching
the LNB active power consumption. If the active LNB falls outside of a specified window, the RSW
automatically switches to the backup LNB.
1.2 System
1.2.1 Headless Operation (ODU Only)
The RSW is headless, meaning that it can be operated without the use of an Indoor Unit (IDU).
All monitoring and control (M&C) can be performed over Ethernet using the Web Interface or via
SNMP. TheOutdoor Unit(ODU) contains all control circuitry and is connected to the user’s system
through the Interfacility Link (IFL).
1.2.2 System with Optional IDU
The Indoor Unit (IDU) is an optional add-on which provides a 1U server rack with an M&C
interface. The IDU interfaces with the ODU via an LCD panel and buttons, and has configurable
alarms in the event of an ODU fault.

2.2.3 Baseplate installation
Refer to the diagram below for the location of all mounting holes on the redundant switch
baseplate. Depending on the redundant switch configuration, some holes may be inaccessible.
Follow these general guidelines when mounting the redundant switch:
•Engage a minimum of 15 holes
•Use medium strength threadlocker

2.3 ODU IFL installation
This section covers the steps to install the IFL to the ODU.
The IFL consists of:
•1 x Power cable
•1 x Ethernet cable
•1 x RF Cable
1. Locate the ODU side of the IFL (labeled “ODU”).
2. Attach the RF cable to the IF1 connector as shown below.
3. Attach the PWR connector to the ODU. Ensure that the cable is threaded onto the
connector.
4. If you have purchased the optional IDU, proceed to Section 2.4. If the RSW is being
operated in the headless configuration, you can now power on the system by connecting
the PWR cable to AC power.

2.4 IDU installation (Optional)
This section outlines the steps to install the IDU.
1. Connect the ODU RF cable to one of the IF PASS THRU connectors. Use the applicable
RF connector type for the IFL provided.
2. Connect the modem RF cable to the unused IF PASS THRU connector.
a. If the IFL uses an N connector, the modem must also be connected to the N PASS
THRU section.
b. If the IFL uses an F connector, the modem must also be connected to the F PASS
THRU section.
3. Connect the Ethernet RJ-45 connector from the IFL to the ETH ODU port.
4. (Optional) Connect the Network port to any external network connection (cable not
included).

5. Connect the AC OUT port to the AC Power connector on the IFL.
6. Connect the AC IN port to the IDU power cable. Ensure that the cable is threaded onto
the connector.
7. Power on the system.
2.5 Safety Ground
A safety ground connection point is provided on the ODU and IDU. If the AC power input has no
earth ground, it is strongly recommended to connect one at the ODU grounding point and IDU
grounding point (if applicable). The grounding point locations are shown below.

ODU Monitoring and Control
3.1 Fault Monitoring
The RSW monitors the current consumption of all LNBs. The system determines if a fault has
occurred based on the current thresholds listed below. These limits are user configurable through
the Web Interface, SNMP, or the optional IDU. It is the user’s responsibility to optimize these
thresholds based on the application.
Upper Limit: If the current rises above this value, an overcurrent fault will be triggered.
Upper Warning: If the current rises above this value, an overcurrent warning will be triggered.
Lower Warning: If the current falls below this value, an undercurrent warning will be triggered.
Lower Limit: If the current falls below this value, an undercurrent fault will be triggered.
3.2 Operation Mode
3.2.1 Automatic Mode
While the Manual Override is disabled, the RSW will run in Automatic Mode. While in Automatic
Mode, the RSW automatically switches from the Active LNB to the Standby LNB if there is a fault
present on the Active LNB. The table below summarizes the RSW actions based on the fault
status while in Automatic Mode.

3.2.2 Manual Override Mode
While the Manual Override is enabled, the RSW will run in Manual Override Mode. In this mode,
the RSW does not take any action based on the fault state of the LNBs. This mode allows the
user to select what LNB is active without restrictions. The table below summarizes the RSW
actions based on the fault status while in Manual Override Mode.

3.3 LNB Power
3.3.1 Integrated ULC
The RSW has an integrated Universal LNB Controller (ULC) which can be configured by the user.
When the ULC setting is enabled, both the Active and Standby LNB receive power from the ULC.
The table below outlines the output voltage and tone for each configurable band. In the case that
a single band LNB is used, the system will be limited to BAND 1.

3.3.2 Power over IF Cable
If the power to the LNB is being supplied by an external source, the ULC must be set to
DISABLED. In this operating mode, the Active Device is supplied with the IF power and the
Standby Device is provided with 18V.
