Configuring CDM-625s for 1:1 Redundancy

CDM‐625 Advanced Satellite Modem Installation and Operation Manual
(CEFD P/N MN‐CDM625)
The CDM‐625 Advanced Satellite Modem automatically detects if it is connected to a 1:1
redundancy system – the steps required to configure both modems are therefore minimal, with
some exceptions:
•
If the CDM‐625 has the optional IP Packet
Processor installed and enabled, 1:1
Redundancy is controlled from the CDM‐625
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
menu here, as Packet Processor Redundancy is enabled automatically.
If it is desired 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.
3.2.1 User Remote Ethernet M&C Interface
The user may configure one of the CDM‐625'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.
This configuration must be enabled on both modems.
Refer to the CDM‐625 Advanced Satellite Modem Installation and Operation Manual for
instructions to configure one of the four 10/100 Ethernet ports for each modem for remote
Ethernet M&C.
Dedicated Management Port Mode is not configurable 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's four 10/100
Ethernet Ports is used for each modem at any given time.
