Installation and configuration

Creation

SNMP Main connection

This connector uses a Simple Network Management Protocol (SNMP) connection and requires the following input during element creation:

SNMP CONNECTION:

  • IP address/host: The polling IP of the device.

SNMP Settings:

  • Port number: The port of the connected device, by default 161.
  • Get community string: The community string used when reading values from the device, by default public.
  • Set community string: The community string used when setting values on the device, by default private.

Usage

General

This page displays the main device parameters. It is divided in two main sections:

  • System Information:

    • Model Number: The model number of the modem.
    • Hardware Revision: The hardware revision of the modem, in the format xx.y, where xx indicates the main (bottom) card and y indicates the top (modem) card.
    • Software Revision
    • Serial Number
    • System Up Time
    • KST System Information: The equipment type and the M&C, upconverter, downconverter, and HPA serial, assembly and firmware numbers.

  • Device Overall Status:

    • Unit Alarm: Shows whether modem unit faults are present.
    • Tx Traffic Alarm: Shows whether modem TX traffic faults are present.
    • Rx Traffic Alarm: Shows whether modem RX traffic faults are present.
    • Offline Unit Status: Displays the fault status information of the offline modem.
    • Unit Test Mode

With the Save Configuration button, you can save the current configuration. The Factory Reset button allows you to reset the device to the factory defaults.

For systems with packet processor KST or CSAT modules, you can toggle polling of the relevant information with the Poll Packet Processor Module Information, Poll KST Module Information and Poll CSAT Module Information toggle buttons.

Admin - Access / SNMP

On this page, you can configure the IP addresses of the host, which is necessary to enable communication with the CDM-625A web server interface and to set administration information for the CDM-625A SNMP feature.

The page is divided in two main sections:

  • Host Access List:

    • Access List: Allows you to grant access via HTTP and SNMP to a defined list of client machines.
    • Access List Overview: Allows you to define which remote clients can connect when the access list is enabled. For each entry, you can specify an IP Address and a Subnet Mask to define a unique class of machines that are allowed access.
    • Authentication Check: Allows you to test if a username/password combination is correct. The combination must be as follows: 1S:<NONCE>:<USERNAME>:<PASSWORD>).
    • Remote Control: Allows you to indicate whether the device should work in local or remote mode, and also the type of remote mode.

  • SNMP:

    • Trap IP 1 / Trap IP 2: Allows you to assign up to two SNMP trap IP addresses.
    • Trap Version: Allows you to set the trap version to SNMPv1 or SNMPv2, using the drop-down box.
    • Trap Community String: Allows you to assign the SNMP trap community string. The community string should consist of at least 0 and at most 20 alphanumeric characters.

These options (with the exception of Remote Control) are only available when the device is working in Local mode (See "Config - Utilities" section below).

Admin - Firmware

This page displays the firmware booting information, such as the Bootrom, Image 1 and Image 2. You can also configure the Running Image using the Boot From parameter.

Admin - FAST

A number of optional features can be activated on the unit. Fully Accessible System Topology (FAST) access codes are register-specific, unique authorization codes that can be purchased from Comtech EF Data.

  • Equipment ID: This read-only section displays the operational status for a number of FAST-enabled features.
  • Hardware: This section lists the installed and currently operational FAST-enabled features, as well as uninstalled FAST-enabled features that are available for purchase and activation from Comtech EF Data.
