R2MFC MBM back and underside elements | Nortel Networks guide

24 Chapter 2 Overview

RS232 port

There is an RJ-45 serial port connector named RS232 on the faceplate of the R2MFC MBM. The N0026100 cable, shipped with the R2MFC MBM, is used to connect a computer to the RS232 port for advanced configuration or for CLI-based diagnostics of the R2MFC MBM. Appendix D, “CLI Cable Pinout,” on page 113 shows the pinout information to make a new N0026100 cable.

E1 Status LEDs

The R2MFC MBM has four visual status monitor indicators in the middle section of the faceplate. They are:

•ERR Tx — indicates a Transmit error on the E1

•ERR Rx — indicates a Receive error on the E1

•ALM Tx — indicates a Transmit alarm on the E1

•ALM Rx — indicates a Receive alarm on the E1

Bantam jacks

The R2MFC MBM contains Bantam Jacks in the middle of the faceplate, to be used for connecting diagnostic equipment. The jacks are labeled DIAG.

BNC and RJ-48 connectors

The R2MFC MBM has both BNC and RJ-48 external E1 connectors located on the far right of the faceplate. These connectors are used to connect the R2MFC MBM to the Central Office (CO).

The default interface will be based on the country code selected. Mexico is the factory default. See Appendix A, “Configuring DIP switch settings and definitions,” on page 91 for the country code default settings.

R2MFC MBM back and underside elements

The back and underside of the R2MFC MBM contain the following elements:

•“Power connectors” on page 25

•“MBM DIP switches” on page 25
