Introduction
This chapter provides steps for solving problems if the MiniArray
III
fails. Your MiniArray
III
was
thoroughly tested at the factory before it was shipped. If you are unable to make a successful
connection, it is possible that the MiniArray
III
is defective. However, it is more likely that the
source of your problem lies elsewhere. As with any microcomputer product, start with simple
hardware and software problems, and then work toward more complex problems (i.e.,
operating system and/or applications).
Troubleshooting
The following troubleshooting process addresses some of the typical problems and with
some basic solutions. If a problem arises while you are in an application, refer to the
software documentation.
• No Video
• Verify that power is ON, and LED in power switch is lit.
• Verify that SBC and any other adapter boards are connected properly.
NOTE: Make sure to turn power OFF to reconnect boards.
• Verify that monitor is turned ON, and verify that power is connected to
monitor and video cable is connected to video connector on SBC.
• Verify that two or four 72-pin, memory SIMMs are connected properly on the
SBC. The SIMMs they must be the same brand, size and speed.
• If some device other than a modem is connected to COM 1, verify that the
DCD jumper is not installed.
• Remove all connectors from the SBC and adapter boards, except the video
connector, and then power ON the MiniArray
III
. If MiniArray
III
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.
• Verify that fan in front of card cage is running. If power is on and fan is
stopped, check to be sure power connectors from power supply to midplane
are fully connected.
• If problem persists, contact MultiTech's Technical Support Department, refer
to Chapter 6 of this manual.
• SBC does not boot correctly or hangs after video appears
• Run BIOS Setup Utility to verify correct configuration for system and drives
(press <DEL> as system boots).
• If boot PROM is used, verify that network and adapter card are configured
properly to see the network.
