MultiCommManager User Guide

Introduction

This chapter provides information that can be used to identify and fix problems with the

MultiCommManager system. Problems can be observed at the rack front panel (LEDs, seven-

segment display), the management PC’s screen, or via audio alarm or alarm report. In addition,

problems can be found when performing the diagnostic tests documented in this chapter.

For specific MultiModem troubleshooting information, refer to the modem card user guide. For

basic Windows messages, refer to your Windows manuals or Help screens.

POST (Power On Self Test)

When rack power is applied, a self-test is performed to exercise front panel elements. Refer to the

rack user guide for further information.

MultiModemManager Link Problems

I can’t see my local racks

Check the settings on your MultiModemManager MIC (link) card.

1. Make sure that the IRQ, shared memory address, and I/O addresses are available for the

MultiModemManager link card. A good way to do this is to remove the card from your PC

and in Windows 3.x run MSD (the Microsoft diagnostics tool). In Windows 95 select My

you which of these resources are available for use. Even after checking, you may have to try

different combinations of the above settings.

2. Make sure that the Node ID switch, which is accessible through the back of the computer, is

set to all switches closed (Node ID 255). If your computer is a PS/2, make sure that the Node

ID is set to 255 on the Reference Diskette.

3. Make sure that Setup|Legacy Management|Broadcast Local Racks is selected.

4. Make sure there is an MultiModemManager link terminator in the last rack of the daisy

chain.
