Table 2-1 Maximum Recommended Cable Lengths NOTE Line Speed Cable Length (Feet) Allowed Loss T-1 Long Haul 6000 36dB@772 khz D&I Short Haul 655 3dB@772 kHz 57.6 kbps 100 30 115.2 kbps 50 15 If you exceed these recommended cable lengths, you must compensate for any resulting problems by reducing the baud rate, using low capacitance cable, etc. Exceed these distances at your own risk. 2.5.1 Connecting a Console Terminal In order to access the ROM Monitor and boot the CSMIM-T1 for the first time, you will need to connect a terminal to the Console Port. Please use the adapters supplied in the accessory kit shipped with the module, as the CSMIM-T1 Console port is a different configuration than other Console ports. Follow the steps in this section to connect a console terminal to the console port located on the front panel of the CSMIM-T1. 1. Connect the Console Terminal’s I/O connector to the RJ45 cable (the accessory kit includes a cable) using a DB-25 DTE drop adapter. 2. Plug the RJ45 connector into the console port located on the front panel of the CSMIM-T1. 3. When the connector clicks into place, the connection is secure. Appendix A describes the console port’s signal/pin allocation. 4. Turn on the Console Terminal and set the terminal to 9600 baud, eight data bits, no parity, one stop bit, and XON/XOFF flow control. The ROM Monitor assumes that this terminal is CRT-based and displays the backspace (BS) character accordingly. CSMIM-T1 Hardware Installation Guide Chapter 2: INSTALLING THE CSMIM-T1 To put the CSMIM-T1 into ROM Monitor mode, press the SET UP button within 30 seconds of powering up. You can also reset and set up the CSMIM-T1 by pressing the SET UP button until the TRAF LED comes ON, release the button and then press it again. This will reboot the module, and it will come up into ROM Monitor mode. NO TES The CSMIM-T1 takes approximately 3 minutes to boot in the ROM Monitor mode, depending on network traffic. During the boot process, the TEST LED remains on. The red ATTN light is ON when the unit is in ROM Monitor state. 2.5.2 Connecting a T1 Network Interface The T1 Network Interface is used to connect the CSMIM-T1 to the T1 line. The T1 Network Interface port is located on the front panel of the CSMIM-T1. To connect to the T-1 network, simply plug the RJ48C connector located on the T1 Network Interface Cable into the T1 Network Interface port located on the front panel of the CSMIM-T1. When the connector clicks into place, the connection is secure. Appendix A describes the T1 Network Interface port’s signal/pin allocation. CSMIM-T1 Hardware Installation Guide Power-up and Test 2.5.3 Connecting a Drop/Insert Interface The Drop/Insert Interface is used to connect various CSMIM-T1 channels to a local PBX or other equipment. The Drop/Insert Interface port is located on the front panel of the CSMIM-T1. To connect your local equipment to the CSMIM-T1, simply plug the RJ48C connector located on the Drop/Insert Interface Cable into the Drop/Insert Interface port located on the front panel of the CSMIM-T1. When the connector clicks into place, the connection is secure. Appendix A describes the Drop/Insert Interface port’s signal/pin allocation. ! CAUTION The CSMIM-T1 can incur damage if the cables conduct transients such as those induced by lightning strikes, etc. 2.6 POWER-UP AND TEST 1. Apply power (or insert into MMAC). The CSMIM-T1 now runs its ROM-resident power-up diagnostics. The indicators momentarily light and then turn off, except for the ON LINE LED and some status LEDs. If the diagnostics complete successfully, the CSMIM-T1 either enters SET UP Mode and waits for configuration data to be entered, or boots its operational image from Flash. You can enter configuration information through a terminal connected to the console port. The ROM monitor prompt (monitor::) appears on the terminal. If the ATTN and the STAT LEDs are flashing together, there is a CSMIM-T1 hardware failure. Contact Technical Support. If the ATTN LED is flashing, there is a network or network interface failure. An error message will display on the console. If a network or network interface failure occurs, typing q accesses the ROM Monitor prompt. Check the network connection, and then see the net command in Chapter 3. See Chapter 5 for additional troubleshooting information. 2. Verify the CSMIM-T1 hardware configuration. CSMIM-T1 Hardware Installation Guide Chapter 2: INSTALLING THE CSMIM-T1 At the monitor prompt on the console, type config and press the Return key.
