Operations Manual, Redundant System Controllers 209351 REV B 69
Skip the following steps if the controller is not configured as a primary power source for
the system's LNBs.
Re-calibration of LNB's fault window:
14. Make sure the LNBs are reliably connected to the controller;
15. Make sure that all LNBs are normally operational prior to system calibration;
16. Make sure the controller is configured for tracking both LNA/LNB and
external faults, if not sure, repeat steps 8 to 14;
17. Press the Main Menu key;
18. Select menu item 6.Calibr. and press the Enter key;
19. Select item 1.Fault Window and press the Enter key;
20. Select item 1.8% and press the Enter key;
21. Press the Main Menu key;
22. Select menu item 6.Calibr. and press the Enter key;
23. Select item 3.Calibrate LNAs and press the Enter key.
The controller should now be configured to work in a VSAT 1:1 Redundancy system.
6.4 Identifying and Replacing a Failed Power Supply
A power supply fault is always considered a major fault, and will cause the front panel
Summary Alarm and Power Supply Alarm LEDs to illuminate. To identify which power
supply module is faulted, follow these steps:
1. On the front panel keypad, press the Main Menu key.
2. Select menu item 1.Sys Info and press the Enter key.
3. The resulting screen shows the status of both power supplies PS1 and PS2
on the left side of the display. The controller monitors the output voltage of
each power supply module. If the output voltage level for a power supply is
above 23V, the display will read Normal. If the output voltage drops below
22V, the display will read Fault.
When looking at the back panel of the RCP, PS1 is on the left and PS2 is on the right.
6.4.1 Removing a Faulted Power Supply Module
To remove a faulted power supply module from the RCP chassis, perform the following
steps:
1. Loosen the two captured thumbscrews securing the module to the chassis;
2. Slide the module out of the chassis;
3. Unplug the quick-disconnect power pole connectors.
