Cdm-570L Or Cdm-570Al Non-Ip Redundancy Configuration - Comtech EF Data CRS-170A Installation And Operation Manual

CRS-170A L-Band 1:1 Redundancy Switch
Modem and Switch Configuration
Because the modem automatically detects if it is connected to a 1:1 redundancy system, the steps
required to configure both modems are minimal. Modem configuration, monitor and control are
possible through local or remote means (Figure 4-4):
•
Local Control – Use the modem front panel to fully configure, monitor, and control the modem
operation:
o The LEDs indicate, in a summary fashion, the status of the modem.
o The VFD (Vacuum fluorescent Display) is an active display showing two lines of 24
characters each. It produces a blue light with adjustable brightness. Nested menus
display all available options and prompt you to carry out a required action.
o The keypad comprises six individual keyswitches. The keys have a positive 'click' action
that provides tactile feedback. Enter data via the keypad. Data, prompts, and messages
are displayed on the VFD.
•
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 Telnet Command Line
Interface (CLI) or the CDM-570L/A HTTP Interface.

CDM-570L or CDM-570AL Non-IP Redundancy Configuration

Do these steps for setup of CDM-570L or CDM-570AL modems for 1:1 Redundancy, when the terrestrial
data type is non-Ethernet (i.e. RS422, G.703).
Step Task
Enable 1:1 Redundancy on both modems:
1
• From the CLI Main Menu, press 'E' to open the 1:1 Redundancy Configuration page.
Press 'R' to toggle 1:1 Redundancy as [Enabled].
o
Press 'S' to ""Save Parameters to permanent storage".
o
• Alternately, using the HTTP Interface 'REDUNDANCY' page:
Use the drop-down list in the 1:1 Redundancy Control section of this page to select Enabled.
o
Click [Submit] to save.
o
If you submit any changes to this web page when the CDM-570AL optional IP Packet
Processor is INSTALLED, you must also open the 'Admin | Pap Save' page and
immediately click [Save PaP Parameters].
Connect all cables to the modems and the CRS-170A. This includes the control cable, IF cable and data
2
'Y'cables.
