3Com Router Module Guide Chapter 3 Multifunctional Interface Modules Caution: Before connecting an SA module, confirm the model of the equipment to be connected to the SA module (that is, sync/async mode, DTE/DCE mode, and so on), signaling criterion required by the access equipment, baud rate, and timing clock. I. Connecting interface cable of Router 4-Port Serial MIM Step 1: Plug the DB-100 connector of a Router 4-Port Serial MIM conversion cable to the appropriate DB-100 port on the Router 4-Port Serial MIM module; Step 2: Select a correct sync/async serial interface cable. Connect one end of the cable to the DB50 connector of the Router 4-Port Serial MIM conversion cable and the other end to: z Port of CSU/DSU, if the WAN is a DDN line; z Serial port of analog modem, if the WAN is a dial-up line; Step 3: 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 4: Check the behavior of the LINK LED on the Router 4-Port Serial MIM panel. It is OFF when the line is faulty and signal is out of synchronization. Caution: You should connect a cable to the port with the correct mark. Misplugging is prone to impair the SIC/MIM and even damage the router. 3.7 ROUTER 2 AND 4-PORT ENHANCED SERIAL MIM 3.7.1 Introduction ROUTER 2 AND 4-PORT ENHANCED SERIAL MIM, 2-/4-port enhanced high-speed sync/async serial interface card, transmits, receives, and processes data on the synchronous/asynchronous serial interface. They support both synchronous and asynchronous modes. In the former case, they support the DTE/DCE mode. I.
