1.4 Environmental Use Information A. Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions located in the user manual furnished by the manufacturer of your equipment rack. B. Mechanical loading - Mounting of equipment in a rack should be such that a hazardous condition does not exist due to uneven weight distribution. C.
2.0 Installation 2.1 Mechanical The 2412-x08 consists of one Controller PCB housed in a 1 RU (1 3/4 inch high) by 19 inches wide by 16 inch deep chassis. A switching, ±12, +24, +5 VDC power supply provides power for the assemblies. The 2412-x08 can be secured to a rack using the 4 holes on the front panel. Figure 2.1 shows how the 2412-x08 is assembled. POWER SUPPLY POWER SUPPLY •••••••• •••••••• (Redundant Optional) FIGURE 2.

2.4 Operation 2.4.1 Installing and Operating the 2412-x08 1. Install the 2412-x08 in the equipment rack. 2. 3. Connect 100-240 ±10% VAC, 47 - 63 Hz to the AC input. (Dual, redundant AC inputs, if redundant power, Option R) on the back panel (Figure 2.2). Be sure the POWER LEDs, DS6, A (and B if redundant) are ON. (Figure 2.3). 4. Connect a -35 to 0 dBm, 50-200 MHz signal to INPUTS, J1, J5, J7 and J9. (Figure 2.2). 5. Connect OUTPUTS J2, J6, J8 and J10 (Figure 2.2) to the desired equipment. 6.
2.5 Power On Settings Figure 2.5 shows the various Front Panel LCD Displays that you will see during the Power Up sequence and the Settings modes. The first two displays (Power Up, displaying Model # and Rev. Level and IP Address, displaying the units IP Address (if Ethernet option installed) are only displayed briefly during the Power On sequence. The Normal Display is what you will see while the unit is in normal operating mode, showing the AGC (Level) or MGC (Gain) for each of the individual channels.
2.5.2 Gain Changes When you get to this menu, note that the gain changes will be made as you make them but if you do not wish to save the changes you have made, scroll to “R” and push the Menu/Execute switch and select “NO” in the “SAVE SETTINGS?” window or do not press the Menu/Execute switch; simply do nothing for approximately 30 seconds, and the system will return to the normal operating mode. To change the MGC Gain or AGC Level: Push the Menu/Execute switch to get to the gain setting. See Figure 2.
2.6 Menu Settings All program changes must start with the operation of the Menu/Execute switch and must also end with the operation of the Menu/Execute switch verified by the “Save Settings?” Menu. If this sequence is not followed, none of the changes will take effect. If programming is initiated and no operator action takes place for approximately 30 seconds (before the final press of the Menu/Execute switch) the display will revert to its previous status and you will need to start over. Figure 2.
3.0 Ethernet Interface Installation and Operation (Option W8, W18 or W28) This manual applies to Cross Technologies products equipped with a 10/100 Base-T compatible Ethernet interface for control and monitoring of its operating parameters. The following sections describe the operation and setup of those interfaces. An HTML script interface allows the user to monitor and control the converter using a standard web browser. SNMP (Simple Network Management Protocol) is also supported.
Figure 3.1: Configuration Manager Screen (Example above shows Configuration Manger Screen for Model 2412-408) Once logged in, you will be presented with the Configuration Manager web page. In the left frame of the Configuration Manager click on Network to display the Network Settings screen. Enter the IP address, Subnet mask, and Gateway address with delimiter dots (example: 192.168.192.47). Click “Apply Settings” in the left frame to apply the new settings in the network device. 2412-408 Manual, Rev.

3.4 SNMP Configuration Setting of SNMP parameters such as Community Write and Community Read strings requires a Telnet® connection to port 9999. The following instructions explain how to establish such a Telnet connection using Windows XP's utility Hyper Terminal. Start the Hyper Terminal application and select “New Connection” from the “File” drop down menu. The next screen is a “Connect To” dialog box. 1. Enter the IP address of the 2412-x08 in the “Host address:” field. 2.
process SNMP Set & Get commands if you do not enter least one (1) IP addresses of an SNMP manager. If you select Public, access is allowed for any number of authorized IP addresses of SNMP Managers. It is not required to enter IP Addresses of SNMP Managers. Figure 3.5: Device Server Configuration Menu Once you have completed you SNMP set up, select item #9, “SAVE AND EXIT” 2412-408 Manual, Rev.
