3Com Router Module Guide Chapter 3 Multifunctional Interface Modules Step 4: Connect the E1 cable to the device to be connected. Step 5: Power on the Router, and check the LEDs of the corresponding slot on the front panel: ON means that the MIM is operating normally and OFF means that the POST of the MIM has failed. In the latter case, please contact your agent; Step 6: Check the behavior of the LINK LED on the module panel. It is OFF when fault has occurred on the link and signal is out of synchronization. In this case, please check the link. 3.9 Router 4-Port ISDN-S/T MIM Module 3.9.1 Introduction 4-port ISDN BRI interface module (Router 4-Port ISDN-S/T MIM) serves to transmit/receive and handle four channels of data streams on the ISDN BRI S/T interface.

Step 4: Connect the E1 cable to the device to be connected.
Step 5: Power on the Router, and check the LEDs of the corresponding slot on the
front panel: ON means that the MIM is operating normally and OFF means that the
POST of the MIM has failed. In the latter case, please contact your agent;
Step 6: Check the behavior of the LINK LED on the module panel. It is OFF when fault
has occurred on the link and signal is out of synchronization. In this case, please
check the link.
