2.5MAKING CONNECTIONS

This section describes how to connect the CSMIM-T1 to a console to access the boot commands, and connecting the T-1 interface as well as the Drop and Insert connection.

Table 2-1 Maximum Recommended Cable Lengths

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

NOTE

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.

2.5.1Connecting 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.
