LPOD C-/Ku-Band Outdoor Amplifier/ Block Up Converter (BUC) Revision 3
Appendix A MN-LPOD
A–3
Follow these steps to set up a 1:1 redundant system:
Step Description
1
Turn both units off, and then connect them to the redundant system hardware using the
proper cables.
2
Turn on Unit #2, and change its serial remote address from 1 (factory default) to a valid
unique value (typically 2) so that it does not conflict with any other unit in the system.
3
Change Unit #2’s IP address from the factory default (192.168.1.4.24) to a valid unique
value (typically 192.168.1.3.24) so that it does not conflict with any other unit in the
system.
4
Enable redundant mode by setting the ESW command (typically ESW=1 or ESW=2 – see
Appendix B. REMOTE CONTROL for more information). You may hear the waveguide
switch / switches throw when redundant mode is enabled. Unit #2 is now the online unit.
5
Turn on Unit #1.
6
Change Unit #1’s serial remote address / IP address if necessary (typically the factory
default values are correct).
7
Enable redundant mode by setting the ESW command (typically ESW=1 or ESW=2 – see
Appendix B. REMOTE CONTROL for more information). You may hear the waveguide
switch / switches throw when redundant mode is enabled. Unit #1 is now the online unit.
8
Setup all parameters for Unit #1 so that the configuration can be copied to Unit #2
(AMP, MUT, ATT, etc… See Appendix B. REMOTE CONTROL for more information).
A.4 Applicable Redundancy Commands
Remote commands applicable to redundancy operations are as follows:
Remote Command Meaning Functional Description
RED
Redundancy Online/Offline
Reports the appropriate units online/offline
status. Also used to force a unit to go active
(online).
ESW
Enable Switch Mode
Puts the unit into redundancy or standalone
(manual) mode.
AFR
Auto Fault Recovery
Sets the latching state of faults. Either they will
latch to the faulted state or they will recover
automatically.
AOF
Attenuation Offset
Individual attenuation command, used to adjust
out small differences in power levels of different
amplifier
For detailed information on these commands, refer to Appendix B. REMOTE CONTROL.
A.5 Redundancy System Assembly Kits
Several kits are available from Comtech EF Data to mount and install standalone or redundant
LPODs, depending on the type of unit ordered and its operational frequency.
Refer to Chapter 2. SYSTEM CONNECTIONS, INSTALLATION AND OPERATION for
the available assembly kit options for 1:1 LPOD standalone configurations.
