CRS-170A L-Band 1:1 Redundancy Switch MN/CRS170A.IOM
Modem and Switch Configuration Revision 13
4–18
• Serial Remote Control – Configuration, monitoring and control of redundant systems is
possible via remote means over an RS-485 multi-drop bus using Windows Command-Line,
where data is transmitted in asynchronous serial form using ASCII characters.
• Ethernet Remote Control – Configuration, monitoring and control of redundant systems is
possible via remote means over an Ethernet connection using the CDM-7XX HTTP (Web
Server) Interface.
4.6.1 Non-IP Redundancy Configuration
Do these steps for setup of the CDM-710GL, -710, or -700 modems for 1:1 Redundancy when
the terrestrial data type is non-Ethernet (e.g., ASI, HSSI, G.703):
Step
Task
1
Enable the redundancy state for both modems. From the modem front panel:
CONFIG: AUX (Redundancy Mode)  ENA/DIS – set to Enable.
2
Connect all cables – including the control cable, IF cable and data cables – to the modems and the
CRS-170A.

4.6.2 IP Redundancy Configuration
Do these steps for setup of the CDM-710GL, -710, or -700 modems for 1:1 IP Redundancy (i.e.,
when the terrestrial data type is Gigabit Ethernet (GigE or GbE)):
Step
Task
1
Before connecting the modems to the CRS-170A, you must first configure the following IP module
settings on each modem. From the modem front panel:
CONFIG: AUX (Redundancy Mode)  ENA/DIS set to Disable.
2
Enable the redundancy state for both modems. From the modem front panel:
CONFIG: AUX (Redundancy Mode)

ENA/DIS set to Enable.
Press ENTER to save your settings.
3
Connect all cables – including the control cable, IF cable and data cables – to the modems and the
CRS-170A. Additionally, you must use a Layer 2 switch to establish an Ethernet connection between
each modem.

4
Verify that the ONLINE LEDs for the CRS-170A indicate the same online state as displayed by the
modems’ front panel LEDs.
