Solving Startup Problems
In the event of difficulty with your MVME172LX VME embedded
controller, try the simple troubleshooting steps on the following pages
before calling for help or sending the board back for repair. Some of the
procedures will return the board to the factory debugger environment. (The
board was tested under these conditions before it left the factory.) The self-
tests may not run in all user-customized environments.
Table B-1. Troubleshooting MVME172LX Boards
Condition Possible Problem Try This:
I. Nothing works, no
display on the
terminal.
A. If the
RUN (or
FUSES) LED is
not lit, the board
may not be
getting correct
power.
1. Make sure the system is plugged in.
2. Check that the board is securely installed in its backplane or
chassis.
3. Check that all necessary cables are connected to the board, per
this manual.
4. Check for compliance with System Considerations, as described
in this manual.
5. Review the Installation and Startup procedures, as described in
this manual. They include a step-by-step powerup routine. Try it.
B. If the LEDs are
lit, the board may
be in the wrong
slot.
1. For VMEmodules, the processor module (controller) should be
in the first (leftmost) slot.
2. Also check that the “system controller” function on the board is
enabled, per this manual.
C. The “system
console”
terminal may be
configured
incorrectly.
Configure the system console terminal as described in this manual.
