4.2 Configure the CDM-625/As for 1:1 Redundancy

(CEFD P/N MN-CDM625A)
• CDM625 Advanced Satellite Modem Installation and Operation Manual
(CEFD P/N MN-CDM625)
The CDM-625/A Advanced Satellite Modems automatically detect connection to a 1:1 redundancy
system. Typical for either product, the steps required to configure both modems are therefore
minimal, with some exceptions:
• If the CDM-625/A has the optional IP Packet
Processor installed and enabled, 1:1
Redundancy is controlled from the
CDM-625/A Web Server Interface
Redundancy page.
When both the traffic and backup modems
are equipped with the optional IP Packet
Processor and are connected to the CRS-180
L-Band 1:1 Redundancy Switch, there is no
need to use the drop-down menus here, as
Packet Processor Redundancy is enabled
automatically.
If you wish to operate either modem outside of the redundant setup as a standalone unit,
use the drop-down menu to select Packet Processor Redundancy for that specific modem as
Disabled.
• If terrestrial data is not Ethernet, and CnC is not be used, then no modem 1:1 redundancy
configuration is needed. Otherwise, if either apply, refer to the sections that follow.
