4.2 Configure the CDM-625/As for Diversity Switching
• CDM-625A Advanced Satellite Modem Installation and Operation Manual
(CEFD P/N MN-CDM625A)
• CDM-625 Advanced Satellite Modem Installation and Operation Manual
(CEFD P/N MN-CDM625)
The CDM-625A and CDM-625 Advanced Satellite Modems automatically detect connection to a
diversity switching system – 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
Redundancy is controlled from the
, 1:1
CDM-625/A Web Server (HTTP) Interface
Redundancy page.
When both the traffic and backup
modems are equipped with the optional
IP Packet Processor and are connected to
the CDS-100 Diversity Switch, there is no
need to use the drop-down menu 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 will not be used, then no modem 1:1 redundancy
configuration is needed. Otherwise, if either apply, refer to the sections that follow.
4.2.1 User Remote Ethernet M&C Interface
You may configure one of the CDM-625/A’s four available 10/100 Ethernet ports for M&C
Ethernet. As configured in Dedicated Management Port Mode, when the modem is offline the
M&C-designated port remains functional and available for operation, while the three remaining
ports are unavailable. Otherwise, if none of the 10/100 Ethernet ports are reserved for M&C
operation, all four ports become unavailable when the modem is offline.
1) This configuration must be enabled on both modems.
2) You may not configure Dedicated Management Port Mode for use when the
optional IP Packet Processor is installed and enabled. With the IP Packet Processor
enabled, as a means to avoid Ethernet Networking Loops, only one of the
CDM-625/A’s four 10/100 Ethernet Ports is used for each modem at any given time
