IMPORTA T

•

For correct operation of the CRS-170A, the CDM-700 and CDM-710 modems

must have the following installed:

For the CDM-700:

► Firmware Version 1.1.6 (or higher)

► Hardware Revision A (chassis with round-buttoned keypad)

• For the CDM-710:

► Firmware Version 2.4.1 (or higher)

► Hardware Revision A (chassis with round-buttoned keypad)

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.

NOTE: Hardware upgrades are possible only for the Rev. A chassis and later

versions of the CDM-700/710 – 1:1 redundancy operation is not available with

hardware prior to Rev. A.

The User can fully configure, monitor, and control the modem operation from the modem’s front

panel; via the keypad and display, nested menus displaying all available options are used and

prompt the User to carry out a required action.

Refer to the CDM-700 or CDM-710 Installation and Operation Manual for detailed

configuration information.

3.4.1 IP Redundancy Configuration

If the terrestrial data type is GigE, follow the steps outlined in this procedure:

1. Before connecting the modems to the CRS-170A, you will need to first configure the

following IP module settings on the CDM-7x0. From the CDM-7x0 front panel:

CONFIG Æ AUX (Redundancy Mode) Æ ENA/DIS set to Disable.

2. On both modems, enter a unique IP Address that is on the same subnet:

CONFIG Æ REMOTE Æ ETHERNET Æ ADDRESS

3. On both modems, 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:

CONFIG Æ Intfc2 Æ MAN Æ ADDRESS

4. On both modems, set the redundancy to the Enable state:

CONFIG Æ AUX (Redundancy Mode) Æ ENA/DIS set to Enable.
