Configuration of CDM-600s for 1:1 Redundancy
For correct operation of the CRS-150, the CDM-600 modems must have the
following installed:
•
Firmware Version 1.1.0 (or higher)
•
Hardware Revision 3
If the modem does not meet this requirement, contact Comtech EF Data. Flash
firmware upgrades are free and may be downloaded from the CEFD Web page.
Hardware revision upgrades must be performed at CEFD.
The User can fully configure, monitor, and control the operation of the CDM-600 from the
modem front panel (
Figure 5-1
) using the keypad and display, where nested menus displaying all
available options are used and prompt the User to carry out a required action.

Satellite Modem Installation and Operation Manual
.
There are two modes of redundant operation:
automatic
and
manual
.
5.2.1 Automatic Redundant Operation
The procedure to configure each CDM-600 modem for automatic 1:1 redundancy is as follows:
1.
As noted previously, ensure that all cables – i.e., control, IF, utility, and data – have been
properly connected between the modems and the CRS-150 as directed in
Chapter 4.
CABLES AND CONNECTIONS
.
2.
The CDM-600 needs no unique or special settings for operation in a 1:1 redundancy
configuration. However, before proceeding, check that the Auxiliary Serial link between
the two units is functioning correctly:
From the online unit’s front panel,

This screen shows the following:
•
Top line:
Operational Mode (
TEST MODE
or
NORMAL
)
•
Bottom line:
1:1 Link Status (
CONNECTED
or
NOT CONNECTED
), and
Redundancy Status (

If the unit is
not
in 1:1 mode, then recheck that the Auxiliary Serial cables have
been correctly installed before proceeding.
