RAS96 RASCard User Guide

Introduction

This chapter describes steps you can take in the event of a RASCard failure. As with any microcomputer product, start with simple hardware and software tests, and work toward more complex tests or operating system/application software tests.

Be sure to check the cable connections to the RASCard. Also, check the Setup utility configuration settings for your particular site (Chapter 4).

Troubleshooting

The following troubleshooting procedures address typical problems and recommend some basic solutions. If a problem arises while you are in an application, refer to the software documentation.

The RASCard has no video

•Verify that the monitor is plugged in and turned on, and that video cable is connected to the video connector on the RASCard.

•Verify that the RASCard is turned on.

•Verify that system power is on.

•Verify that the RASCard is seated properly in its slot. Note: Make sure to turn power off before reseating cards.

•Verify that the memory SIMMs are seated properly on the RASCard. If two or four SIMMs are installed, they must be the same brand, size and speed. Fill Bank 1 first.

•Remove any other device cards from the segment and turn on the RASCard. If the RASCard has video now, then there is a conflict with one of the device cards. Check the configuration of each device card.

•Remove all connectors from the RASCard except the video connector, then turn on the RASCard. If the RASCard now has video, then there is a problem with one of the cables or one of the peripherals. Try each cable, one at a time, to isolate the bad cable or peripheral.

•Try the RASCard in a different segment (if CC9600) or CommPlete chassis. If this works, there is a problem with the segment or chassis previously used.

•If the problem persists, contact Multi-Tech’s Technical Support Department.

The RASCard does not boot correctly, or hangs after the video appears

•Run the BIOS Setup utility to verify that you have the correct configuration for the system and drives (press DEL as system boots).

•Verify that the RASCard and device cards are seated properly in the CC9600 chassis. Note: Make sure to turn power off before reseating cards.

•Verify that the fan on the CPU heat sink is working. The CPU may be overheating.
