5.2.4.3 Switch to CDM-700, CDM-710, CDM-710G Redundancy Configuration
IMPORTANT
Only the
Rev. A chassis (i.e., chassis with round-buttoned keypad) and later
versions of the CDM-700/710 offer 1:N redundancy operation.
The CRS-300 communicates to the Redundant and Traffic modems via a serial TTL bus
contained within the CDM-700/710/710G DB-15 “Alarms” connector on the modem back panel.
A DB-15 to HD-15 Control Cable connects each modem to the CRS-300.
To configure the CDM-700/710/710G and CRS-300 for 1:N redundancy:
Step Procedure
1 If the terrestrial data type is Ethernet, for each modem, enter a unique IP Address for
the CDI-70 (GigE Interface) that is on the same subnet:
For the CDM-700: CONFIG Æ Intfc1 Æ MAN Æ ADDRESS
For the CDM-710 or CDM-710G: CONFIG Æ Intfc2 Æ MAN Æ ADDRESS
2 The DB-15 “Alarms” connector on the modem back panel must be configured for
“Redundancy Mode”. On each modem, set the redundancy to the Active state:
CONFIG Æ AUX (Redundancy Mode) Æ ENA/DIS set to Enable.
Press ENT to save parameters to flash memory. The CDM-700/710/710G modems do
not have any further COMM menus configured by the User.
3 Power down all CDM-700s/710s/710Gs.
4 Power up all CDM-700s/710s/710Gs. Verify that each Traffic Modem is ONLINE via
the front panel LEDs.
IMPORTANT
All configuration changes can only be made to the Online CDM-700/710/710G and
will require the User to “Save Parameters to permanent storage” to ensure
the configuration change is also applied to the Backup CDM-700/710/710G.
Refer to the CDM-700, CDM-710, or CDM-710G Installation and Operation Manuals for
detailed configuration information.
