APPENDIX A – TROUBLESHOOTING 

 
 
In the unlikely event you encounter a problem using the MIU9.6FPD, refer to the troubleshooting 
information in this appendix. 

 
 
 PROBLEM 

SOLVING

 

 

 

 

Table A-1 offers troubleshooting solutions for modem problems. 

 
 

Table A-1. Troubleshooting Suggestions 

If… 

Perform These Procedures… 

The modem does not respond to the 
attached DTE and all LEDs are off. 

Check the power supply input for your specific 
model.  

The modem does not receive data and 
the green LED on the front panel 
does not blink. 

The receive line pair may be disconnected from 
the modem or polarity may be reversed. Make 
sure the transmission line connection to the 
modem is accurate and secure. 

The modem does not transmit data 
and the red LED on the front panel 
does not blink. 

The attached terminal or DTE may not be 
sending data to the modem. Verify that data is 
being transmitted. 
If data is being transmitted, make sure the RS-
232 cable is sound and securely connected to 
the modem and terminal or DTE.  

All LEDs on the modem module are 
working, but the attached computer 
does not work or the modem receives 
data errors. 

Verify all switch settings on the modem. 
Make sure the modem and computer are 
configured for the same operating speed. 
If necessary, perform the loopback test. 

The baseboard jumper and switches 
have been changed from their factory 
settings. 

See “Baseboard Module Configuration 
Settings.”
