Cabletron Systems CSMIM-T1 User Manual

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.

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. 

Verify the CSMIM-T1 hardware configuration.

The CSMIM-T1 can incur damage if the cables conduct 
transients such as those induced by lightning strikes, etc.
