4. Peak the signal on the satellite, and then adjust polarization per guidance from
NOC staff.
Moisture Migrated Into the Cyber Hardened IBUC
Moisture can enter and damage the IBUC if waveguide gaskets are missing, there is a
hole in the feed window, or there is a break in the coaxial connectors.
To prevent moisture from entering the IBUC,
• Ensure that the paper label is removed from the waveguidre prior to installation
and operation.
• Ensure that the rubber waveguide gasket is intact and fully seated in the grooved
channel before making the connection.
• Use water-resistant wrap (or mastic tape) on all outdoor connectors to ensure a
water
-
tight seal. Mastic tapes are designed to flow and self
-
heal if cut or punctured
For more information about applying water-resistant wrap, see
• Avoid using damaged connectors (for example, scratched mating surfaces,
eccentric or bent center conductors, and so on.).
• Seal all coaxial cable fittings with putty.
Bad Orthogonal Mode Transducer and/or Antenna
If the antenna feedhorn and orthogonal mode transducer (OMT) are not positioned
correctly, the IBUC will not operate properly.
To position the feedhorn and OMT,
• Refer to the antenna manufacturer’s assembly instructions to verify that the
feedhorn and OMT were mounted correctly on the antenna.
• Establish a communications link with the satellite network operations center
(NOC).
• Guided by NOC staff, slowly rotate the outdoor equipment to the appropriate
position.
• If rotation is impossible, it is likely that there is a problem with OMT and it will
need to be returned to the antenna manufacturer.
LED is Red
A red LED indicates only that a fault (or alarm) has occurred and does not necessarily
indicate that transmission has stopped. A flashing red light indicates a minor alarm and
a solid red light indicates a major alarm. You can communicate with the IBUC to
determine what is causing the fault, and then clear the fault condition.
