Appendix B. 1:1 AND 1:2 REDUNDANCY OPERATION B.1 Overview Comtech EF Data’s C-, X-, and KU-Band High-Power Outdoor Power Amplifiers (HPODs) can be used in redundant configuration by connecting the appropriate redundancy loop cable between the user M&C location and each HPOD ‘J4 | REDUNDANT LOOP’ port.
HPOD C-, X-, Ku-Band High-Power Outdoor Amplifier Appendix B MN/HPOD.IOM Revision 8 In 1:1 applications, the BU also stores an offset value, to be used when the BU replaces the active unit. This offset may be set with the GOF= command. When the online unit is being “backed up” the BU’s attenuator will be set to this value. This value may be different than the attenuation value of the online unit to compensate for any gain mismatch between the BU and online units.
HPOD C-, X-, Ku-Band High-Power Outdoor Amplifier Appendix B MN/HPOD.IOM Revision 8 While the BU is constantly monitoring both units for their status, if either has a fault, use the last (good) status as the configuration for the BU before the BU goes online. Once the BU goes online, the redundancy auto/manual status reverts to manual mode, and the BU stays online until reset by the user. The user may reset the system by issuing a FBU=0 command to place the units back into auto mode.
