System fails at power-up
-will not run power-on
self-test. May be
accompanied by
combinations of beep
tones from the speaker.
The system is not getting
power.
BIOS detected a failure
SIMM missing or loose.
Hardware failure.
Check the backplane and verify
that +5V power is good. Verify
that the subplane is fully seated
in the VME backplane and the
EPC-8 is fully seated in the
subplane.
See BIOS Beep Codes table
below.
Check that the SIMM is still
present or connected.
This cannot be diagnosed in the
field. Call RadiSys Technical
Support.
Serial port(s) do not
work.
Bad power.
Interrupt conflicts
Port hardware failure.
Verify that backplane +12V and
-12V are good.
An EXM module is using the
same interrupts as COM1 and/or
COM2. Verify that no other
card in the EPC-8 subsystem is
using IRQ3 or IRQ4.
Call RadiSys Technical Support.
System hangs during
boot process (Master
LED on; RUN LED off)
VMEbus has no Slot-1
controller providing bus
timeout.
You are probably loading an
expanded memory manager (for
example, EMM386.EXE) in
your CONFIG.SYS file. This
can cause the system to hang if
- there is no Slot-1 controller
- the Slot-1 controller is not
providing the proper bus
timeout
- the Bus Grant jumpers are not
installed.
