9.0 Start Up and Verification, continued Connect a computer’s network port to the transponder’s Ethernet port using a standard network cable. Launch an Internet browser and enter 192.168.100.1 into the address. The transponder will return the Web page shown below. Click on General to display the key communications parameters including system uptime, IP provisioning mode (IPv4, IPv6 &... -
Page 83: Verifying Correct Hardware Interconnection
9.0 Start Up and Verification, continued 9.2 Verifying Correct Hardware Interconnection NOTICE: The DM3X model provides both BAT A/B and BAT C/D LED indicators and battery harness connectors (supports a maximum 4 battery strings). The BAT A/B and BAT C/D LED indicators on the front panel of the DM3X unit should illuminate solid green once the battery wiring harnesses are correctly installed. -
Page 84: System Status Indicators And Reset Button
9.0 Start Up and Verification, continued 9.3 System Status Indicators and Reset Button As viewed from the front of the unit, the DM3X Transponder utilizes LEDs to indicate system status. During system start up, the LEDs will first blink momentarily then indicate the current status of a variety of parameters on the DM3X Transponder. -
Page 85: Detailed Led Descriptions
9.0 Start Up and Verification, continued 9.3.1 Detailed LED Descriptions After power is applied or a reset occurs, all LEDs will flash in certain patterns indicating the cable modem chipset is starting or restarting. Once it is ready, it will begin the DOCSIS requirement of searching for the downstream frequency lock and the LEDs will follow the detailed descriptions below. -
Page 86: Table 9-1, Scte-Hms Property Table
9.0 Start Up and Verification, continued Rx/Tx Power The Rx/Tx PWR LED utilizes a tricolor LED to provide the installer a quick verification of the modem transmit (Tx) and receive (Rx) RF power levels. The Rx/Tx PWR LED will illuminate green when both the cable modem Tx and cable modem Rx RF power levels are within the range as specified in the SCTE-HMS PropertyTable. -
Page 87: Fig. 9-5, Transponder Web Page, Rf Power Level Indicators
9.0 Start Up and Verification, continued Rx/Tx Power The current RF level status for both the Rx and Tx will be displayed on the colored scale highlighted in black, providing verification of modem RF power levels. Refer to the figure below for an example of the RF power level indicator bars on the Web page. -
Page 88: Resetting The Transponder
9.0 Start Up and Verification, continued 9.3.2 Resetting the Transponder Should the need arise to reset the transponder locally, such as in the case of adding additional power supplies, a generator, or carrying out maintenance activities, do the following: Press and hold the reset button (RST) for approximately three (3) seconds until the ALM/RDY LED stops blinking and turns solid (green). -
Page 89: Dual Ip Mode
9.0 Start Up and Verification, continued 9.5 Dual IP Mode 9.5.1 Overview The DM3X Transponder can operate in either Single (default) or Dual IP mode. In Single IP mode, data from both the cable modem and power supply are accessed and managed through the modem’s IP address on the secure private modem network. -
Page 90: Web Comparison, Single Ip Mode/Dual Ip Mode
9.0 Start Up and Verification, continued 9.5.2 Web Comparison, Single IP Mode/Dual IP Mode To easily determine the configuration of the Communications Module when viewing it on its web page, check the Configuration line as well as the entries for the CM and CPE addresses. A single IP Communications Module will display a CM MAC address only, while a Dual IP Communications Module will also indicate a CPE address. -
Page 91: Configuring Dual Ip Mode
9.0 Start Up and Verification, continued 9.5.3 Configuring Dual IP Mode To switch the DM3X Transponder from Single to Dual IP mode the atiMgmtSnmpSnmpCPEAccess parameter of the Alpha MIB will need to be enabled. The Dual IP enable setting can be set through the DOCSIS Configuration File, the DM3.0 Setup File (atidoc33.cfg), the Provisioning Mode via the Communications Web page or remotely using SNMP by setting the following Alpha MIB: Enabling Dual IP Mode... -

9.0 Start Up and Verification, continued To change the CPE IP address allocation option from DHCP to Static via the Web Server, refer to the following: 1. Connect to DM3X Transponder via Web browser per the procedure in Section 4.0, Web Interface. 2. -
Page 93: Table 9-6, Available Download Options
9.0 Start Up and Verification, continued atidoc33.cfg in Dual IP Mode NOTICE: Refer to Section 3.3.5 for details on using the atidoc33.cfg file to propagate custom settings to field deployed DM3X Series Transponders. In Dual IP mode, the DM3X Transponder will first attempt to download the proprietary configuration file atidoc33.cfg through the CPE’s interface from a TFTP server on the CPE network. -
Page 94: Dual Ip Snmp Community Strings
9.0 Start Up and Verification, continued Specifying atidoc33.cfg name and location via DHCP Tags In the User-defined area of the DHCP Tags, above option 192, the Communications Module will look for the following value: Tag: [Insert Unique Tag Name, e.g. ‘ati-tag’] Value: aticonfig In the Tag value immediately following will be the value for the TFTP server to use: Tag: [Insert Unique Tag Name, e.g. -
Page 95: Security In Dual Ip Mode
9.0 Start Up and Verification, continued 9.5.5 Security in Dual IP Mode In Dual IP mode, additional SNMP security to the DM3X Transponder proprietary MIBs is required since the Communications Module and power supply data is exposed on the CPE network, which may be more vulnerable to packet sniffing and community string deciphering than on the secure cable modem network. -
Page 96: Table 9-9, Secure Access Table Parameters
9.0 Start Up and Verification, continued Method 2: Dual IP Security Using the Secure Access List The DM3X Transponder provides an alternative method of providing additional SNMP security in Dual IP by limiting access to the Communications Module’s CPE address. The Secure Access List method limits remote SNMP access to four IP addresses. -
